 We need to be authenticated to access some of the checkpoints used during benchmarking:
 
 ```sh

+hf auth login
 ```
 
 We use an L40 GPU with 128GB RAM to run the benchmark CI. As such, the benchmarks are configured to run on NVIDIA GPUs. So, make sure you have access to a similar machine (or modify the benchmarking scripts accordingly).

-# Overview
+# BriaTransformer2DModel
 
-The inference pipeline supports and enables a wide range of techniques that are divided into two categories:
+A modified flux Transformer model from [Bria](https://huggingface.co/briaai/BRIA-3.2)
 
-* Pipeline functionality: these techniques modify the pipeline or extend it for other applications. For example, pipeline callbacks add new features to a pipeline and a pipeline can also be extended for distributed inference.
-* Improve inference quality: these techniques increase the visual quality of the generated images. For example, you can enhance your prompts with GPT2 to create better images with lower effort.

+# Bria 3.2
+
+Bria 3.2 is the next-generation commercial-ready text-to-image model. With just 4 billion parameters, it provides exceptional aesthetics and text rendering, evaluated to provide on par results to leading open-source models, and outperforming other licensed models.
+In addition to being built entirely on licensed data, 3.2 provides several advantages for enterprise and commercial use:
+
+- Efficient Compute - the model is X3 smaller than the equivalent models in the market (4B parameters vs 12B parameters other open source models)
+- Architecture Consistency: Same architecture as 3.1—ideal for users looking to upgrade without disruption.
+- Fine-tuning Speedup: 2x faster fine-tuning on L40S and A100.
+
+Original model checkpoints for Bria 3.2 can be found [here](https://huggingface.co/briaai/BRIA-3.2).
+Github repo for Bria 3.2 can be found [here](https://github.com/Bria-AI/BRIA-3.2).

+The `guidance_scale` parameter in the pipeline is there to support future guidance-distilled models when they come up. Note that passing `guidance_scale` to the pipeline is ineffective. To enable classifier-free guidance, please pass `true_cfg_scale` and `negative_prompt` (even an empty negative prompt like " ") should enable classifier-free guidance computations.

+# SkyReels-V2: Infinite-length Film Generative model
+
+[SkyReels-V2](https://huggingface.co/papers/2504.13074) by the SkyReels Team from Skywork AI.
+
+*Recent advances in video generation have been driven by diffusion models and autoregressive frameworks, yet critical challenges persist in harmonizing prompt adherence, visual quality, motion dynamics, and duration: compromises in motion dynamics to enhance temporal visual quality, constrained video duration (5-10 seconds) to prioritize resolution, and inadequate shot-aware generation stemming from general-purpose MLLMs' inability to interpret cinematic grammar, such as shot composition, actor expressions, and camera motions. These intertwined limitations hinder realistic long-form synthesis and professional film-style generation. To address these limitations, we propose SkyReels-V2, an Infinite-length Film Generative Model, that synergizes Multi-modal Large Language Model (MLLM), Multi-stage Pretraining, Reinforcement Learning, and Diffusion Forcing Framework. Firstly, we design a comprehensive structural representation of video that combines the general descriptions by the Multi-modal LLM and the detailed shot language by sub-expert models. Aided with human annotation, we then train a unified Video Captioner, named SkyCaptioner-V1, to efficiently label the video data. Secondly, we establish progressive-resolution pretraining for the fundamental video generation, followed by a four-stage post-training enhancement: Initial concept-balanced Supervised Fine-Tuning (SFT) improves baseline quality; Motion-specific Reinforcement Learning (RL) training with human-annotated and synthetic distortion data addresses dynamic artifacts; Our diffusion forcing framework with non-decreasing noise schedules enables long-video synthesis in an efficient search space; Final high-quality SFT refines visual fidelity. All the code and models are available at [this https URL](https://github.com/SkyworkAI/SkyReels-V2).*

+You can find all the original SkyReels-V2 checkpoints under the [Skywork](https://huggingface.co/collections/Skywork/skyreels-v2-6801b1b93df627d441d0d0d9) organization.

+### A _Visual_ Demonstration
+
+The example below has the following parameters:
+
+- `base_num_frames=97`
+- `num_frames=97`
+- `num_inference_steps=30`
+- `ar_step=5`
+- `causal_block_size=5`
+
+With `vae_scale_factor_temporal=4`, expect `5` blocks of `5` frames each as calculated by:
+
+`num_latent_frames: (97-1)//vae_scale_factor_temporal+1 = 25 frames -> 5 blocks of 5 frames each`
+
+And the maximum context length in the latent space is calculated with `base_num_latent_frames`:
+
+`base_num_latent_frames = (97-1)//vae_scale_factor_temporal+1 = 25 -> 25//5 = 5 blocks`
+
+Asynchronous Processing Timeline:
+```text
+┌─────────────────────────────────────────────────────────────────┐
+│ Steps:    1    6   11   16   21   26   31   36   41   46   50   │
+│ Block 1: [■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■]                       │
+│ Block 2:      [■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■]                  │
+│ Block 3:           [■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■]             │
+│ Block 4:                [■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■]        │
+│ Block 5:                     [■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■]   │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+For Long Videos (`num_frames` > `base_num_frames`):
+`base_num_frames` acts as the "sliding window size" for processing long videos.
+
+Example: `257`-frame video with `base_num_frames=97`, `overlap_history=17`
+```text
+┌──── Iteration 1 (frames 1-97) ────┐
+│ Processing window: 97 frames      │ → 5 blocks,
+│ Generates: frames 1-97            │   async processing
+└───────────────────────────────────┘
+            ┌────── Iteration 2 (frames 81-177) ──────┐
+            │ Processing window: 97 frames            │
+            │ Overlap: 17 frames (81-97) from prev    │ → 5 blocks,
+            │ Generates: frames 98-177                │   async processing
+            └─────────────────────────────────────────┘
+                        ┌────── Iteration 3 (frames 161-257) ──────┐
+                        │ Processing window: 97 frames             │
+                        │ Overlap: 17 frames (161-177) from prev   │ → 5 blocks,
+                        │ Generates: frames 178-257                │   async processing
+                        └──────────────────────────────────────────┘
+```
+
+Each iteration independently runs the asynchronous processing with its own `5` blocks.
+`base_num_frames` controls:
+1. Memory usage (larger window = more VRAM)
+2. Model context length (must match training constraints)
+3. Number of blocks per iteration (`base_num_latent_frames // causal_block_size`)
+
+Each block takes `30` steps to complete denoising.
+Block N starts at step: `1 + (N-1) x ar_step`
+Total steps: `30 + (5-1) x 5 = 50` steps
+
+
+Synchronous mode (`ar_step=0`) would process all blocks/frames simultaneously:
+```text
+┌──────────────────────────────────────────────┐
+│ Steps:       1            ...            30  │
+│ All blocks: [■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■] │
+└──────────────────────────────────────────────┘
+```
+Total steps: `30` steps
+
+
+An example on how the step matrix is constructed for asynchronous processing:
+Given the parameters: (`num_inference_steps=30, flow_shift=8, num_frames=97, ar_step=5, causal_block_size=5`)
+```
+- num_latent_frames = (97 frames - 1) // (4 temporal downsampling) + 1 = 25
+- step_template = [999, 995, 991, 986, 980, 975, 969, 963, 956, 948,
+                   941, 932, 922, 912, 901, 888, 874, 859, 841, 822,
+                   799, 773, 743, 708, 666, 615, 551, 470, 363, 216]
+```
+
+The algorithm creates a `50x25` `step_matrix` where:
+```
+- Row 1:  [999×5, 999×5, 999×5, 999×5, 999×5]
+- Row 2:  [995×5, 999×5, 999×5, 999×5, 999×5]
+- Row 3:  [991×5, 999×5, 999×5, 999×5, 999×5]
+- ...

+- ...
+- Row 50: [  0×5,   0×5,   0×5,   0×5, 216×5]
+```
+
+Detailed Row `6` Analysis:
+```
+- step_matrix[5]:      [ 975×5,  999×5,   999×5,   999×5,   999×5]
+- step_index[5]:       [   6×5,    1×5,     0×5,     0×5,     0×5]
+- step_update_mask[5]: [True×5, True×5, False×5, False×5, False×5]
+- valid_interval[5]:   (0, 25)
+```
+
+Key Pattern: Block `i` lags behind Block `i-1` by exactly `ar_step=5` timesteps, creating the
+staggered "diffusion forcing" effect where later blocks condition on cleaner earlier blocks.

+Refer to the [Reduce memory usage](../../optimization/memory) guide for more details about the various memory saving techniques.
+
+From the original repo:
+>You can use --ar_step 5 to enable asynchronous inference. When asynchronous inference, --causal_block_size 5 is recommended while it is not supposed to be set for synchronous generation... Asynchronous inference will take more steps to diffuse the whole sequence which means it will be SLOWER than synchronous mode. In our experiments, asynchronous inference may improve the instruction following and visual consistent performance.

 # Diffusers
 
-🤗 Diffusers is the go-to library for state-of-the-art pretrained diffusion models for generating images, audio, and even 3D structures of molecules. Whether you're looking for a simple inference solution or want to train your own diffusion model, 🤗 Diffusers is a modular toolbox that supports both. Our library is designed with a focus on [usability over performance](conceptual/philosophy#usability-over-performance), [simple over easy](conceptual/philosophy#simple-over-easy), and [customizability over abstractions](conceptual/philosophy#tweakable-contributorfriendly-over-abstraction).
+Diffusers is a library of state-of-the-art pretrained diffusion models for generating videos, images, and audio.
 
-The library has three main components:
+The library revolves around the [`DiffusionPipeline`], an API designed for:
 
-- State-of-the-art diffusion pipelines for inference with just a few lines of code. There are many pipelines in 🤗 Diffusers, check out the table in the pipeline [overview](api/pipelines/overview) for a complete list of available pipelines and the task they solve.
-- Interchangeable [noise schedulers](api/schedulers/overview) for balancing trade-offs between generation speed and quality.
-- Pretrained [models](api/models) that can be used as building blocks, and combined with schedulers, for creating your own end-to-end diffusion systems.

-## Install with conda
-
-After activating your virtual environment, with `conda` (maintained by the community):
+<hfoption id="conda">
 
 ```bash
 conda install -c conda-forge diffusers
 ```
 
-## Install from source
+</hfoption>
+<hfoption id="source">
 
-Before installing 🤗 Diffusers from source, make sure you have PyTorch and 🤗 Accelerate installed.
+A source install installs the `main` version instead of the latest `stable` version. The `main` version is useful for staying updated with the latest changes but it may not always be stable. If you run into a problem, open an [Issue](https://github.com/huggingface/diffusers/issues/new/choose) and we will try to resolve it as soon as possible.
 
-To install 🤗 Accelerate:
+Make sure [Accelerate](https://huggingface.co/docs/accelerate/index) is installed.
 
 ```bash
-pip install accelerate
+uv pip install accelerate
 ```
 
-Then install 🤗 Diffusers from source:
+Install Diffusers from source with the command below.
 
 ```bash
-pip install git+https://github.com/huggingface/diffusers
+uv pip install git+https://github.com/huggingface/diffusers
 ```
 
-This command installs the bleeding edge `main` version rather than the latest `stable` version.
-The `main` version is useful for staying up-to-date with the latest developments.
-For instance, if a bug has been fixed since the last official release but a new release hasn't been rolled out yet.
-However, this means the `main` version may not always be stable.
-We strive to keep the `main` version operational, and most issues are usually resolved within a few hours or a day.
-If you run into a problem, please open an [Issue](https://github.com/huggingface/diffusers/issues/new/choose) so we can fix it even sooner!
+</hfoption>
+</hfoptions>
 
 ## Editable install
 
-You will need an editable install if you'd like to:
+An editable install is recommended for development workflows or if you're using the `main` version of the source code. A special link is created between the cloned repository and the Python library paths. This avoids reinstalling a package after every change.
 
-* Use the `main` version of the source code.
-* Contribute to 🤗 Diffusers and need to test changes in the code.
-
-Clone the repository and install 🤗 Diffusers with the following commands:
+Clone the repository and install Diffusers with the following commands.
 
 ```bash
 git clone https://github.com/huggingface/diffusers.git
 cd diffusers
+uv pip install -e ".[torch]"
 ```
 
-<frameworkcontent>
-<pt>
-```bash
-pip install -e ".[torch]"
-```
-</pt>
-<jax>
-```bash
-pip install -e ".[flax]"
-```
-</jax>
-</frameworkcontent>
+> [!WARNING]
+> You must keep the `diffusers` folder if you want to keep using the library with the editable install.
 
-These commands will link the folder you cloned the repository to and your Python library paths.
-Python will now look inside the folder you cloned to in addition to the normal library paths.
-For example, if your Python packages are typically installed in `~/anaconda3/envs/main/lib/python3.10/site-packages/`, Python will also search the `~/diffusers/` folder you cloned to.

-
-Now you can easily update your clone to the latest version of 🤗 Diffusers with the following command:
+Update your cloned repository to the latest version of Diffusers with the command below.
 
 ```bash
 cd ~/diffusers/
 git pull
 ```
 
-Your Python environment will find the `main` version of 🤗 Diffusers on the next run.

 ## Cache
 
-Model weights and files are downloaded from the Hub to a cache which is usually your home directory. You can change the cache location by specifying the `HF_HOME` or `HUGGINFACE_HUB_CACHE` environment variables or configuring the `cache_dir` parameter in methods like [`~DiffusionPipeline.from_pretrained`].

 ## Telemetry logging
 
-Our library gathers telemetry information during [`~DiffusionPipeline.from_pretrained`] requests.
-The data gathered includes the version of 🤗 Diffusers and PyTorch/Flax, the requested model or pipeline class,
-and the path to a pretrained checkpoint if it is hosted on the Hugging Face Hub.

+# AutoPipelineBlocks
+
+[`~modular_pipelines.AutoPipelineBlocks`] are a multi-block type containing blocks that support different workflows. It automatically selects which sub-blocks to run based on the input provided at runtime. This is typically used to package multiple workflows - text-to-image, image-to-image, inpaint - into a single pipeline for convenience.
+
+This guide shows how to create [`~modular_pipelines.AutoPipelineBlocks`].
+
+Create three [`~modular_pipelines.ModularPipelineBlocks`] for text-to-image, image-to-image, and inpainting. These represent the different workflows available in the pipeline.
+
+<hfoptions id="auto">

+        print("running the text-to-image workflow")
+        # Add your text-to-image logic here

+        return components, state
+```
+
+</hfoption>
+</hfoptions>
+
+Create an [`~modular_pipelines.AutoPipelineBlocks`] class that includes a list of the sub-block classes and their corresponding block names.
+
+You also need to include `block_trigger_inputs`, a list of input names that trigger the corresponding block. If a trigger input is provided at runtime, then that block is selected to run. Use `None` to specify the default block to run if no trigger inputs are detected.
+
+Lastly, it is important to include a `description` that clearly explains which inputs trigger which workflow. This helps users understand how to run specific workflows.
+
+```py
+from diffusers.modular_pipelines import AutoPipelineBlocks
+
+class AutoImageBlocks(AutoPipelineBlocks):
+    # List of sub-block classes to choose from
+    block_classes = [block_inpaint_cls, block_i2i_cls, block_t2i_cls]
+    # Names for each block in the same order
+    block_names = ["inpaint", "img2img", "text2img"]
+    # Trigger inputs that determine which block to run
+    # - "mask" triggers inpaint workflow
+    # - "image" triggers img2img workflow (but only if mask is not provided)
+    # - if none of above, runs the text2img workflow (default)
+    block_trigger_inputs = ["mask", "image", None]
+    # Description is extremely important for AutoPipelineBlocks
+
+    def description(self):
+        return (
+            "Pipeline generates images given different types of conditions!\n"
+            + "This is an auto pipeline block that works for text2img, img2img and inpainting tasks.\n"
+            + " - inpaint workflow is run when `mask` is provided.\n"
+            + " - img2img workflow is run when `image` is provided (but only when `mask` is not provided).\n"
+            + " - text2img workflow is run when neither `image` nor `mask` is provided.\n"
+        )
+```
+
+It is **very** important to include a `description` to avoid any confusion over how to run a block and what inputs are required. While [`~modular_pipelines.AutoPipelineBlocks`] are convenient, it's conditional logic may be difficult to figure out if it isn't properly explained.
+
+Create an instance of `AutoImageBlocks`.
+
+```py
+auto_blocks = AutoImageBlocks()
+```
+
+For more complex compositions, such as nested [`~modular_pipelines.AutoPipelineBlocks`] blocks when they're used as sub-blocks in larger pipelines, use the [`~modular_pipelines.SequentialPipelineBlocks.get_execution_blocks`] method to extract the a block that is actually run based on your input.
+
+```py
+auto_blocks.get_execution_blocks("mask")
+```

+# ComponentsManager
+
+The [`ComponentsManager`] is a model registry and management system for Modular Diffusers. It adds and tracks models, stores useful metadata (model size, device placement, adapters), prevents duplicate model instances, and supports offloading.
+
+This guide will show you how to use [`ComponentsManager`] to manage components and device memory.
+
+## Add a component
+
+The [`ComponentsManager`] should be created alongside a [`ModularPipeline`] in either [`~ModularPipeline.from_pretrained`] or [`~ModularPipelineBlocks.init_pipeline`].
+
+> [!TIP]
+> The `collection` parameter is optional but makes it easier to organize and manage components.
+
+<hfoptions id="create">
+<hfoption id="from_pretrained">
+
+```py
+from diffusers import ModularPipeline, ComponentsManager
+
+comp = ComponentsManager()
+pipe = ModularPipeline.from_pretrained("YiYiXu/modular-demo-auto", components_manager=comp, collection="test1")
+```
+
+</hfoption>
+<hfoption id="init_pipeline">
+
+```py
+from diffusers import ComponentsManager
+from diffusers.modular_pipelines import SequentialPipelineBlocks
+from diffusers.modular_pipelines.stable_diffusion_xl import TEXT2IMAGE_BLOCKS
+
+t2i_blocks = SequentialPipelineBlocks.from_blocks_dict(TEXT2IMAGE_BLOCKS)
+
+modular_repo_id = "YiYiXu/modular-loader-t2i-0704"
+components = ComponentsManager()
+t2i_pipeline = t2i_blocks.init_pipeline(modular_repo_id, components_manager=components)
+```
+
+</hfoption>
+</hfoptions>
+
+Components are only loaded and registered when using [`~ModularPipeline.load_components`] or [`~ModularPipeline.load_default_components`]. The example below uses [`~ModularPipeline.load_default_components`] to create a second pipeline that reuses all the components from the first one, and assigns it to a different collection
+
+```py
+pipe.load_default_components()
+pipe2 = ModularPipeline.from_pretrained("YiYiXu/modular-demo-auto", components_manager=comp, collection="test2")
+```
+
+Use the [`~ModularPipeline.null_component_names`] property to identify any components that need to be loaded, retrieve them with [`~ComponentsManager.get_components_by_names`], and then call [`~ModularPipeline.update_components`] to add the missing components.
+
+```py
+pipe2.null_component_names 
+['text_encoder', 'text_encoder_2', 'tokenizer', 'tokenizer_2', 'image_encoder', 'unet', 'vae', 'scheduler', 'controlnet']
+
+comp_dict = comp.get_components_by_names(names=pipe2.null_component_names)
+pipe2.update_components(**comp_dict)
+```
+
+To add individual components, use the [`~ComponentsManager.add`] method. This registers a component with a unique id.
+
+```py
+from diffusers import AutoModel
+
+text_encoder = AutoModel.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder")
+component_id = comp.add("text_encoder", text_encoder)
+comp
+```
+
+Use [`~ComponentsManager.remove`] to remove a component using their id.
+
+```py
+comp.remove("text_encoder_139917733042864")
+```
+
+## Retrieve a component
+
+The [`ComponentsManager`] provides several methods to retrieve registered components.
+
+### get_one
+
+The [`~ComponentsManager.get_one`] method returns a single component and supports pattern matching for the `name` parameter. If multiple components match, [`~ComponentsManager.get_one`] returns an error.
+
+| Pattern     | Example                          | Description                               |
+|-------------|----------------------------------|-------------------------------------------|
+| exact       | `comp.get_one(name="unet")`      | exact name match                          |
+| wildcard    | `comp.get_one(name="unet*")`     | names starting with "unet"                |
+| exclusion   | `comp.get_one(name="!unet")`     | exclude components named "unet"           |
+| or          | `comp.get_one(name="unet&#124;vae")`  | name is "unet" or "vae"                   |
+
+[`~ComponentsManager.get_one`] also filters components by the `collection` argument or `load_id` argument.
+
+```py
+comp.get_one(name="unet", collection="sdxl")
+```
+
+### get_components_by_names
+
+The [`~ComponentsManager.get_components_by_names`] method accepts a list of names and returns a dictionary mapping names to components. This is especially useful with [`ModularPipeline`] since they provide lists of required component names and the returned dictionary can be passed directly to [`~ModularPipeline.update_components`].
+
+```py
+component_dict = comp.get_components_by_names(names=["text_encoder", "unet", "vae"])
+{"text_encoder": component1, "unet": component2, "vae": component3}
+```
+
+## Duplicate detection
+
+It is recommended to load model components with [`ComponentSpec`] to assign components with a unique id that encodes their loading parameters. This allows [`ComponentsManager`] to automatically detect and prevent duplicate model instances even when different objects represent the same underlying checkpoint.
+
+```py
+from diffusers import ComponentSpec, ComponentsManager
+from transformers import CLIPTextModel
+
+comp = ComponentsManager()
+
+# Create ComponentSpec for the first text encoder
+spec = ComponentSpec(name="text_encoder", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder", type_hint=AutoModel)
+# Create ComponentSpec for a duplicate text encoder (it is same checkpoint, from the same repo/subfolder)
+spec_duplicated = ComponentSpec(name="text_encoder_duplicated", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder", type_hint=CLIPTextModel)
+
+# Load and add both components - the manager will detect they're the same model
+comp.add("text_encoder", spec.load())
+comp.add("text_encoder_duplicated", spec_duplicated.load())
+```
+
+This returns a warning with instructions for removing the duplicate.
+
+```py
+ComponentsManager: adding component 'text_encoder_duplicated_139917580682672', but it has duplicate load_id 'stabilityai/stable-diffusion-xl-base-1.0|text_encoder|null|null' with existing components: text_encoder_139918506246832. To remove a duplicate, call `components_manager.remove('<component_id>')`.
+'text_encoder_duplicated_139917580682672'
+```
+
+You could also add a component without using [`ComponentSpec`] and duplicate detection still works in most cases even if you're adding the same component under a different name.
+
+However, [`ComponentManager`] can't detect duplicates when you load the same component into different objects. In this case, you should load a model with [`ComponentSpec`].
+
+```py
+text_encoder_2 = AutoModel.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder")
+comp.add("text_encoder", text_encoder_2)
+'text_encoder_139917732983664'
+```
+
+## Collections
+
+Collections are labels assigned to components for better organization and management. Add a component to a collection with the `collection` argument in [`~ComponentsManager.add`].
+
+Only one component per name is allowed in each collection. Adding a second component with the same name automatically removes the first component.
+
+```py
+from diffusers import ComponentSpec, ComponentsManager
+
+comp = ComponentsManager()
+# Create ComponentSpec for the first UNet
+spec = ComponentSpec(name="unet", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="unet", type_hint=AutoModel)
+# Create ComponentSpec for a different UNet
+spec2 = ComponentSpec(name="unet", repo="RunDiffusion/Juggernaut-XL-v9", subfolder="unet", type_hint=AutoModel, variant="fp16")
+
+# Add both UNets to the same collection - the second one will replace the first
+comp.add("unet", spec.load(), collection="sdxl")
+comp.add("unet", spec2.load(), collection="sdxl")
+```
+
+This makes it convenient to work with node-based systems because you can:
+
+- Mark all models as loaded from one node with the `collection` label.
+- Automatically replace models when new checkpoints are loaded under the same name.
+- Batch delete all models in a collection when a node is removed.
+
+## Offloading
+
+The [`~ComponentsManager.enable_auto_cpu_offload`] method is a global offloading strategy that works across all models regardless of which pipeline is using them. Once enabled, you don't need to worry about device placement if you add or remove components.
+
+```py
+comp.enable_auto_cpu_offload(device="cuda")
+```
+
+All models begin on the CPU and [`ComponentsManager`] moves them to the appropriate device right before they're needed, and moves other models back to the CPU when GPU memory is low.
+
+You can set your own rules for which models to offload first.

+# Guiders
+
+[Classifier-free guidance](https://huggingface.co/papers/2207.12598) steers model generation that better match a prompt and is commonly used to improve generation quality, control, and adherence to prompts. There are different types of guidance methods, and in Diffusers, they are known as *guiders*. Like blocks, it is easy to switch and use different guiders for different use cases without rewriting the pipeline.
+
+This guide will show you how to switch guiders, adjust guider parameters, and load and share them to the Hub.
+
+## Switching guiders
+
+[`ClassifierFreeGuidance`] is the default guider and created when a pipeline is initialized with [`~ModularPipelineBlocks.init_pipeline`]. It is created by `from_config` which means it doesn't require loading specifications from a modular repository. A guider won't be listed in `modular_model_index.json`.
+
+Use [`~ModularPipeline.get_component_spec`] to inspect a guider.
+
+```py
+t2i_pipeline.get_component_spec("guider")
+ComponentSpec(name='guider', type_hint=<class 'diffusers.guiders.classifier_free_guidance.ClassifierFreeGuidance'>, description=None, config=FrozenDict([('guidance_scale', 7.5), ('guidance_rescale', 0.0), ('use_original_formulation', False), ('start', 0.0), ('stop', 1.0), ('_use_default_values', ['start', 'guidance_rescale', 'stop', 'use_original_formulation'])]), repo=None, subfolder=None, variant=None, revision=None, default_creation_method='from_config')
+```
+
+Switch to a different guider by passing the new guider to [`~ModularPipeline.update_components`].
+
+> [!TIP]
+> Changing guiders will return text letting you know you're changing the guider type.
+> ```bash
+> ModularPipeline.update_components: adding guider with new type: PerturbedAttentionGuidance, previous type: ClassifierFreeGuidance
+> ```
+
+```py

+
+Use [`~ModularPipeline.get_component_spec`] again to verify the guider type is different.

+
+## Loading custom guiders
+
+Guiders that are already saved on the Hub with a `modular_model_index.json` file are considered a `from_pretrained` component now instead of a `from_config` component.
+
+```json
+{
+  "guider": [
+    null,
+    null,
+    {
+      "repo": "YiYiXu/modular-loader-t2i-guider",
+      "revision": null,
+      "subfolder": "pag_guider",
+      "type_hint": [
+        "diffusers",
+        "PerturbedAttentionGuidance"
+      ],
+      "variant": null
+    }
+  ]
+}
+```
+
+The guider is only created after calling [`~ModularPipeline.load_default_components`] based on the loading specification in `modular_model_index.json`.
+
+```py
+t2i_pipeline = t2i_blocks.init_pipeline("YiYiXu/modular-doc-guider")
+# not created during init
+assert t2i_pipeline.guider is None
+t2i_pipeline.load_default_components()
+# loaded as PAG guider
+t2i_pipeline.guider
+```
+
+
+## Changing guider parameters
+
+The guider parameters can be adjusted with either the [`~ComponentSpec.create`] method or with [`~ModularPipeline.update_components`]. The example below changes the `guidance_scale` value.
+
+<hfoptions id="switch">
+<hfoption id="create">
+
+```py
+guider_spec = t2i_pipeline.get_component_spec("guider")

+```
+
+</hfoption>
+</hfoptions>
+
+## Uploading custom guiders
+
+Call the [`~utils.PushToHubMixin.push_to_hub`] method on a custom guider to share it to the Hub.

+
+<hfoptions id="upload">
+<hfoption id="modular_model_index.json">
+
+Edit the `modular_model_index.json` file and add a loading specification for the guider by pointing to a folder containing the guider config.

+
+</hfoption>
+<hfoption id="update_components">
+
+Change the [`~ComponentSpec.default_creation_method`] to `from_pretrained` and use [`~ModularPipeline.update_components`] to update the guider and component specifications as well as the pipeline config.
+

+> Changing the creation method will return text letting you know you're changing the creation type to `from_pretrained`.
+> ```bash
+> ModularPipeline.update_components: changing the default_creation_method of guider from from_config to from_pretrained.

+
+```py
+guider_spec = t2i_pipeline.get_component_spec("guider")
+guider_spec.default_creation_method="from_pretrained"

+guider_spec.subfolder="pag_guider"
+pag_guider = guider_spec.load()
+t2i_pipeline.update_components(guider=pag_guider)
+```
+
+To make it the default guider for a pipeline, call [`~utils.PushToHubMixin.push_to_hub`]. This is an optional step and not necessary if you are only experimenting locally.
+
+```py
+t2i_pipeline.push_to_hub("YiYiXu/modular-doc-guider")

+# LoopSequentialPipelineBlocks
+
+[`~modular_pipelines.LoopSequentialPipelineBlocks`] are a multi-block type that composes other [`~modular_pipelines.ModularPipelineBlocks`] together in a loop. Data flows circularly, using `intermediate_inputs` and `intermediate_outputs`, and each block is run iteratively. This is typically used to create a denoising loop which is iterative by default.
+
+This guide shows you how to create [`~modular_pipelines.LoopSequentialPipelineBlocks`].
+
+## Loop wrapper
+
+[`~modular_pipelines.LoopSequentialPipelineBlocks`], is also known as the *loop wrapper* because it defines the loop structure, iteration variables, and configuration. Within the loop wrapper, you need the following variables.
+
+- `loop_inputs` are user provided values and equivalent to [`~modular_pipelines.ModularPipelineBlocks.inputs`].
+- `loop_intermediate_inputs` are intermediate variables from the [`~modular_pipelines.PipelineState`] and equivalent to [`~modular_pipelines.ModularPipelineBlocks.intermediate_inputs`].
+- `loop_intermediate_outputs` are new intermediate variables created by the block and added to the [`~modular_pipelines.PipelineState`]. It is equivalent to [`~modular_pipelines.ModularPipelineBlocks.intermediate_outputs`].
+- `__call__` method defines the loop structure and iteration logic.
+
+```py
+import torch
+from diffusers.modular_pipelines import LoopSequentialPipelineBlocks, ModularPipelineBlocks, InputParam, OutputParam
+
+class LoopWrapper(LoopSequentialPipelineBlocks):
+    model_name = "test"
+    @property
+    def description(self):
+        return "I'm a loop!!"
+    @property
+    def loop_inputs(self):
+        return [InputParam(name="num_steps")]
+    @torch.no_grad()
+    def __call__(self, components, state):
+        block_state = self.get_block_state(state)
+        # Loop structure - can be customized to your needs
+        for i in range(block_state.num_steps):
+            # loop_step executes all registered blocks in sequence
+            components, block_state = self.loop_step(components, block_state, i=i)
+        self.set_block_state(state, block_state)
+        return components, state
+```
+
+The loop wrapper can pass additional arguments, like current iteration index, to the loop blocks.
+
+## Loop blocks
+
+A loop block is a [`~modular_pipelines.ModularPipelineBlocks`], but the `__call__` method behaves differently.
+
+- It recieves the iteration variable from the loop wrapper.
+- It works directly with the [`~modular_pipelines.BlockState`] instead of the [`~modular_pipelines.PipelineState`].
+- It doesn't require retrieving or updating the [`~modular_pipelines.BlockState`].
+
+Loop blocks share the same [`~modular_pipelines.BlockState`] to allow values to accumulate and change for each iteration in the loop.
+
+```py
+class LoopBlock(ModularPipelineBlocks):
+    model_name = "test"
+    @property
+    def inputs(self):
+        return [InputParam(name="x")]
+    @property
+    def intermediate_outputs(self):
+        # outputs produced by this block
+        return [OutputParam(name="x")]
+    @property
+    def description(self):
+        return "I'm a block used inside the `LoopWrapper` class"
+    def __call__(self, components, block_state, i: int):
+        block_state.x += 1
+        return components, block_state
+```
+
+## LoopSequentialPipelineBlocks
+
+Use the [`~modular_pipelines.LoopSequentialPipelineBlocks.from_blocks_dict`] method to add the loop block to the loop wrapper to create [`~modular_pipelines.LoopSequentialPipelineBlocks`].
+
+```py
+loop = LoopWrapper.from_blocks_dict({"block1": LoopBlock})
+```
+
+Add more loop blocks to run within each iteration with [`~modular_pipelines.LoopSequentialPipelineBlocks.from_blocks_dict`]. This allows you to modify the blocks without changing the loop logic itself.
+
+```py
+loop = LoopWrapper.from_blocks_dict({"block1": LoopBlock(), "block2": LoopBlock})
+```

+# States
+
+Blocks rely on the [`~modular_pipelines.PipelineState`] and [`~modular_pipelines.BlockState`] data structures for communicating and sharing data.
+
+| State | Description |
+|-------|-------------|
+| [`~modular_pipelines.PipelineState`] | Maintains the overall data required for a pipeline's execution and allows blocks to read and update its data. |
+| [`~modular_pipelines.BlockState`] | Allows each block to perform its computation with the necessary data from `inputs`|
+
+This guide explains how states work and how they connect blocks.
+
+## PipelineState
+
+The [`~modular_pipelines.PipelineState`] is a global state container for all blocks. It maintains the complete runtime state of the pipeline and provides a structured way for blocks to read from and write to shared data.
+
+There are two dict's in [`~modular_pipelines.PipelineState`] for structuring data.
+
+- The `values` dict is a **mutable** state containing a copy of user provided input values and intermediate output values generated by blocks. If a block modifies an `input`, it will be reflected in the `values` dict after calling `set_block_state`.
+
+```py
+PipelineState(
+  values={
+    'prompt': 'a cat'
+    'guidance_scale': 7.0
+    'num_inference_steps': 25
+    'prompt_embeds': Tensor(dtype=torch.float32, shape=torch.Size([1, 1, 1, 1]))
+    'negative_prompt_embeds': None
+  },
+)
+```
+
+## BlockState
+
+The [`~modular_pipelines.BlockState`] is a local view of the relevant variables an individual block needs from [`~modular_pipelines.PipelineState`] for performing it's computations.
+
+Access these variables directly as attributes like `block_state.image`.
+
+```py
+BlockState(
+    image: <PIL.Image.Image image mode=RGB size=512x512 at 0x7F3ECC494640>
+)
+```
+
+When a block's `__call__` method is executed, it retrieves the [`BlockState`] with `self.get_block_state(state)`, performs it's operations, and updates [`~modular_pipelines.PipelineState`] with `self.set_block_state(state, block_state)`.
+
+```py
+def __call__(self, components, state):
+    # retrieve BlockState
+    block_state = self.get_block_state(state)
+
+    # computation logic on inputs
+
+    # update PipelineState
+    self.set_block_state(state, block_state)
+    return components, state
+```
+
+## State interaction
+
+[`~modular_pipelines.PipelineState`] and [`~modular_pipelines.BlockState`] interaction is defined by a block's `inputs`, and `intermediate_outputs`.
+
+- `inputs`, a block can modify an input - like `block_state.image` - and this change can be propagated globally to [`~modular_pipelines.PipelineState`] by calling `set_block_state`.
+- `intermediate_outputs`, is a new variable that a block creates. It is added to the [`~modular_pipelines.PipelineState`]'s `values` dict and is available as for subsequent blocks or accessed by users as a final output from the pipeline.

+# ModularPipeline
+
+[`ModularPipeline`] converts [`~modular_pipelines.ModularPipelineBlocks`]'s into an executable pipeline that loads models and performs the computation steps defined in the block. It is the main interface for running a pipeline and it is very similar to the [`DiffusionPipeline`] API.
+
+The main difference is to include an expected `output` argument in the pipeline.

+```
+
+</hfoption>
+</hfoptions>
+
+This guide will show you how to create a [`ModularPipeline`] and manage the components in it.
+
+## Adding blocks
+
+Blocks are [`InsertableDict`] objects that can be inserted at specific positions, providing a flexible way to mix-and-match blocks.
+
+Use [`~modular_pipelines.modular_pipeline_utils.InsertableDict.insert`] on either the block class or `sub_blocks` attribute to add a block.
+
+```py
+# BLOCKS is dict of block classes, you need to add class to it
+BLOCKS.insert("block_name", BlockClass, index)
+# sub_blocks attribute contains instance, add a block instance to the  attribute
+t2i_blocks.sub_blocks.insert("block_name", block_instance, index)
+```
+
+Use [`~modular_pipelines.modular_pipeline_utils.InsertableDict.pop`] on either the block class or `sub_blocks` attribute to remove a block.
+
+```py
+# remove a block class from preset
+BLOCKS.pop("text_encoder")
+# split out a block instance on its own
+text_encoder_block = t2i_blocks.sub_blocks.pop("text_encoder")
+```
+
+Swap blocks by setting the existing block to the new block.
+
+```py
+# Replace block class in preset
+BLOCKS["prepare_latents"] = CustomPrepareLatents
+# Replace in sub_blocks attribute using an block instance
+t2i_blocks.sub_blocks["prepare_latents"] = CustomPrepareLatents()
+```
+
+## Creating a pipeline
+
+There are two ways to create a [`ModularPipeline`]. Assemble and create a pipeline from [`ModularPipelineBlocks`] or load an existing pipeline with [`~ModularPipeline.from_pretrained`].
+
+You should also initialize a [`ComponentsManager`] to handle device placement and memory and component management.
+
+> [!TIP]
+> Refer to the [ComponentsManager](./components_manager) doc for more details about how it can help manage components across different workflows.
+
+<hfoptions id="create">
+<hfoption id="ModularPipelineBlocks">
+
+Use the [`~ModularPipelineBlocks.init_pipeline`] method to create a [`ModularPipeline`] from the component and configuration specifications. This method loads the *specifications* from a `modular_model_index.json` file, but it doesn't load the *models* yet.
+
+```py
+from diffusers import ComponentsManager
+from diffusers.modular_pipelines import SequentialPipelineBlocks
+from diffusers.modular_pipelines.stable_diffusion_xl import TEXT2IMAGE_BLOCKS
+
+t2i_blocks = SequentialPipelineBlocks.from_blocks_dict(TEXT2IMAGE_BLOCKS)
+
+modular_repo_id = "YiYiXu/modular-loader-t2i-0704"
+components = ComponentsManager()
+t2i_pipeline = t2i_blocks.init_pipeline(modular_repo_id, components_manager=components)
+```
+
+</hfoption>
+<hfoption id="from_pretrained">
+
+The [`~ModularPipeline.from_pretrained`] method creates a [`ModularPipeline`] from a modular repository on the Hub.
+
+```py
+from diffusers import ModularPipeline, ComponentsManager
+
+components = ComponentsManager()
+pipeline = ModularPipeline.from_pretrained("YiYiXu/modular-loader-t2i-0704", components_manager=components)
+```
+
+Add the `trust_remote_code` argument to load a custom [`ModularPipeline`].
+
+```py
+from diffusers import ModularPipeline, ComponentsManager
+
+components = ComponentsManager()
+modular_repo_id = "YiYiXu/modular-diffdiff-0704"
+diffdiff_pipeline = ModularPipeline.from_pretrained(modular_repo_id, trust_remote_code=True, components_manager=components)
+```
+
+</hfoption>
+</hfoptions>
+
+## Loading components
+
+A [`ModularPipeline`] doesn't automatically instantiate with components. It only loads the configuration and component specifications. You can load all components with [`~ModularPipeline.load_default_components`] or only load specific components with [`~ModularPipeline.load_components`].
+
+<hfoptions id="load">
+<hfoption id="load_default_components">
+
+```py
+import torch
+
+t2i_pipeline.load_default_components(torch_dtype=torch.float16)
+t2i_pipeline.to("cuda")
+```
+
+</hfoption>
+<hfoption id="load_components">
+
+The example below only loads the UNet and VAE.
+
+```py
+import torch
+
+t2i_pipeline.load_components(names=["unet", "vae"], torch_dtype=torch.float16)
+```
+
+</hfoption>
+</hfoptions>
+
+Print the pipeline to inspect the loaded pretrained components.
+
+```py
+t2i_pipeline
+```
+
+This should match the `modular_model_index.json` file from the modular repository a pipeline is initialized from. If a pipeline doesn't need a component, it won't be included even if it exists in the modular repository.
+
+To modify where components are loaded from, edit the `modular_model_index.json` file in the repository and change it to your desired loading path. The example below loads a UNet from a different repository.
+
+```json
+# original
+"unet": [
+  null, null,
+  {
+    "repo": "stabilityai/stable-diffusion-xl-base-1.0",
+    "subfolder": "unet",
+    "variant": "fp16"
+  }
+]
+
+# modified
+"unet": [
+  null, null,
+  {
+    "repo": "RunDiffusion/Juggernaut-XL-v9",
+    "subfolder": "unet",
+    "variant": "fp16"
+  }
+]
+```
+
+### Component loading status
+
+The pipeline properties below provide more information about which components are loaded.
+
+Use `component_names` to return all expected components.
+
+```py
+t2i_pipeline.component_names
+['text_encoder', 'text_encoder_2', 'tokenizer', 'tokenizer_2', 'guider', 'scheduler', 'unet', 'vae', 'image_processor']
+```
+
+Use `null_component_names` to return components that aren't loaded yet. Load these components with [`~ModularPipeline.from_pretrained`].
+
+```py
+t2i_pipeline.null_component_names
+['text_encoder', 'text_encoder_2', 'tokenizer', 'tokenizer_2', 'scheduler']
+```
+
+Use `pretrained_component_names` to return components that will be loaded from pretrained models.
+
+```py
+t2i_pipeline.pretrained_component_names
+['text_encoder', 'text_encoder_2', 'tokenizer', 'tokenizer_2', 'scheduler', 'unet', 'vae']
+```
+
+Use `config_component_names` to return components that are created with the default config (not loaded from a modular repository). Components from a config aren't included because they are already initialized during pipeline creation. This is why they aren't listed in `null_component_names`.
+
+```py
+t2i_pipeline.config_component_names
+['guider', 'image_processor']
+```
+
+## Updating components
+
+Components may be updated depending on whether it is a *pretrained component* or a *config component*.
+
+> [!WARNING]
+> A component may change from pretrained to config when updating a component. The component type is initially defined in a block's `expected_components` field.
+
+A pretrained component is updated with [`ComponentSpec`] whereas a config component is updated by eihter passing the object directly or with [`ComponentSpec`].
+
+The [`ComponentSpec`] shows `default_creation_method="from_pretrained"` for a pretrained component shows `default_creation_method="from_config` for a config component.
+
+To update a pretrained component, create a [`ComponentSpec`] with the name of the component and where to load it from. Use the [`~ComponentSpec.load`] method to load the component.
+
+```py
+from diffusers import ComponentSpec, UNet2DConditionModel
+
+unet_spec = ComponentSpec(name="unet",type_hint=UNet2DConditionModel, repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="unet", variant="fp16")
+unet = unet_spec.load(torch_dtype=torch.float16)
+```
+
+The [`~ModularPipeline.update_components`] method replaces the component with a new one.
+
+```py
+t2i_pipeline.update_components(unet=unet2)
+```
+
+When a component is updated, the loading specifications are also updated in the pipeline config.
+
+### Component extraction and modification

+When you use [`~ComponentSpec.load`], the new component maintains its loading specifications. This makes it possible to extract the specification and recreate the component.
+
+```py
+spec = ComponentSpec.from_component("unet", unet2)
+spec
+ComponentSpec(name='unet', type_hint=<class 'diffusers.models.unets.unet_2d_condition.UNet2DConditionModel'>, description=None, config=None, repo='stabilityai/stable-diffusion-xl-base-1.0', subfolder='unet', variant='fp16', revision=None, default_creation_method='from_pretrained')
+unet2_recreated = spec.load(torch_dtype=torch.float16)
+```
+
+The [`~ModularPipeline.get_component_spec`] method gets a copy of the current component specification to modify or update.
+
+```py
+unet_spec = t2i_pipeline.get_component_spec("unet")
+unet_spec
+ComponentSpec(
+    name='unet',
+    type_hint=<class 'diffusers.models.unets.unet_2d_condition.UNet2DConditionModel'>,
+    repo='RunDiffusion/Juggernaut-XL-v9',
+    subfolder='unet',
+    variant='fp16',
+    default_creation_method='from_pretrained'
+)
+
+# modify to load from a different repository
+unet_spec.repo = "stabilityai/stable-diffusion-xl-base-1.0"
+
+# load component with modified spec
+unet = unet_spec.load(torch_dtype=torch.float16)
+```
+
+## Modular repository
+
+A repository is required if the pipeline blocks use *pretrained components*. The repository supplies loading specifications and metadata.
+
+[`ModularPipeline`] specifically requires *modular repositories* (see [example repository](https://huggingface.co/YiYiXu/modular-diffdiff)) which are more flexible than a typical repository. It contains a `modular_model_index.json` file containing the following 3 elements.
+
+- `library` and `class` shows which library the component was loaded from and it's class. If `null`, the component hasn't been loaded yet.
+- `loading_specs_dict` contains the information required to load the component such as the repository and subfolder it is loaded from.
+
+Unlike standard repositories, a modular repository can fetch components from different repositories based on the `loading_specs_dict`. Components don't need to exist in the same repository.
+
+A modular repository may contain custom code for loading a [`ModularPipeline`]. This allows you to use specialized blocks that aren't native to Diffusers.
+
+```
+modular-diffdiff-0704/
+├── block.py                    # Custom pipeline blocks implementation
+├── config.json                 # Pipeline configuration and auto_map
+└── modular_model_index.json    # Component loading specifications
+```
+
+The [config.json](https://huggingface.co/YiYiXu/modular-diffdiff-0704/blob/main/config.json) file contains an `auto_map` key that points to where a custom block is defined in `block.py`.

+
+# ModularPipelineBlocks
+
+[`~modular_pipelines.ModularPipelineBlocks`] is the basic block for building a [`ModularPipeline`]. It defines what components, inputs/outputs, and computation a block should perform for a specific step in a pipeline. A [`~modular_pipelines.ModularPipelineBlocks`] connects with other blocks, using [state](./modular_diffusers_states), to enable the modular construction of workflows.
+
+A [`~modular_pipelines.ModularPipelineBlocks`] on it's own can't be executed. It is a blueprint for what a step should do in a pipeline. To actually run and execute a pipeline, the [`~modular_pipelines.ModularPipelineBlocks`] needs to be converted into a [`ModularPipeline`].
+
+This guide will show you how to create a [`~modular_pipelines.ModularPipelineBlocks`].
+
+## Inputs and outputs
+
+> [!TIP]
+> Refer to the [States](./modular_diffusers_states) guide if you aren't familiar with how state works in Modular Diffusers.
+
+A [`~modular_pipelines.ModularPipelineBlocks`] requires `inputs`, and `intermediate_outputs`.
+
+- `inputs` are values provided by a user and retrieved from the [`~modular_pipelines.PipelineState`]. This is useful because some workflows resize an image, but the original image is still required. The [`~modular_pipelines.PipelineState`] maintains the original image.
+
+    Use `InputParam` to define `inputs`.
+
+    ```py
+    from diffusers.modular_pipelines import InputParam
+
+    user_inputs = [
+        InputParam(name="image", type_hint="PIL.Image", description="raw input image to process")
+    ]
+    ```
+
+- `intermediate_inputs` are values typically created from a previous block but it can also be directly provided if no preceding block generates them. Unlike `inputs`, `intermediate_inputs` can be modified.
+
+    Use `InputParam` to define `intermediate_inputs`.
+
+    ```py
+    user_intermediate_inputs = [
+        InputParam(name="processed_image", type_hint="torch.Tensor", description="image that has been preprocessed and normalized"),
+    ]
+    ```
+
+- `intermediate_outputs` are new values created by a block and added to the [`~modular_pipelines.PipelineState`]. The `intermediate_outputs` are available as `intermediate_inputs` for subsequent blocks or available as the final output from running the pipeline.
+
+    Use `OutputParam` to define `intermediate_outputs`.
+
+    ```py
+    from diffusers.modular_pipelines import OutputParam
+
+        user_intermediate_outputs = [
+        OutputParam(name="image_latents", description="latents representing the image")
+    ]
+    ```
+
+The intermediate inputs and outputs share data to connect blocks. They are accessible at any point, allowing you to track the workflow's progress.
+
+## Computation logic
+
+The computation a block performs is defined in the `__call__` method and it follows a specific structure.
+
+1. Retrieve the [`~modular_pipelines.BlockState`] to get a local view of the `inputs` and `intermediate_inputs`.
+2. Implement the computation logic on the `inputs` and `intermediate_inputs`.
+3. Update [`~modular_pipelines.PipelineState`] to push changes from the local [`~modular_pipelines.BlockState`] back to the global [`~modular_pipelines.PipelineState`].
+4. Return the components and state which becomes available to the next block.
+
+```py
+def __call__(self, components, state):
+    # Get a local view of the state variables this block needs
+    block_state = self.get_block_state(state)
+
+    # Your computation logic here
+    # block_state contains all your inputs and intermediate_inputs
+    # Access them like: block_state.image, block_state.processed_image
+
+    # Update the pipeline state with your updated block_states
+    self.set_block_state(state, block_state)
+    return components, state
+```
+
+### Components and configs
+
+The components and pipeline-level configs a block needs are specified in [`ComponentSpec`] and [`~modular_pipelines.ConfigSpec`].
+
+- [`ComponentSpec`] contains the expected components used by a block. You need the `name` of the component and ideally a `type_hint` that specifies exactly what the component is.
+- [`~modular_pipelines.ConfigSpec`] contains pipeline-level settings that control behavior across all blocks.
+
+```py
+from diffusers import ComponentSpec, ConfigSpec
+
+expected_components = [
+    ComponentSpec(name="unet", type_hint=UNet2DConditionModel),
+    ComponentSpec(name="scheduler", type_hint=EulerDiscreteScheduler)
+]
+
+expected_config = [
+    ConfigSpec("force_zeros_for_empty_prompt", True)
+]
+```
+
+When the blocks are converted into a pipeline, the components become available to the block as the first argument in `__call__`.
+
+```py
+def __call__(self, components, state):
+    # Access components using dot notation
+    unet = components.unet
+    vae = components.vae
+    scheduler = components.scheduler
+```

+
+# Quickstart
+
+Modular Diffusers is a framework for quickly building flexible and customizable pipelines. At the core of Modular Diffusers are [`ModularPipelineBlocks`] that can be combined with other blocks to adapt to new workflows. The blocks are converted into a [`ModularPipeline`], a friendly user-facing interface developers can use.
+
+This doc will show you how to implement a [Differential Diffusion](https://differential-diffusion.github.io/) pipeline with the modular framework.
+
+## ModularPipelineBlocks
+
+[`ModularPipelineBlocks`] are *definitions* that specify the components, inputs, outputs, and computation logic for a single step in a pipeline. There are four types of blocks.
+
+- [`ModularPipelineBlocks`] is the most basic block for a single step.
+- [`SequentialPipelineBlocks`] is a multi-block that composes other blocks linearly. The outputs of one block are the inputs to the next block.
+- [`LoopSequentialPipelineBlocks`] is a multi-block that runs iteratively and is designed for iterative workflows.
+- [`AutoPipelineBlocks`] is a collection of blocks for different workflows and it selects which block to run based on the input. It is designed to conveniently package multiple workflows into a single pipeline.
+
+[Differential Diffusion](https://differential-diffusion.github.io/) is an image-to-image workflow. Start with the `IMAGE2IMAGE_BLOCKS` preset, a collection of `ModularPipelineBlocks` for image-to-image generation.
+
+```py
+from diffusers.modular_pipelines.stable_diffusion_xl import IMAGE2IMAGE_BLOCKS
+IMAGE2IMAGE_BLOCKS = InsertableDict([
+    ("text_encoder", StableDiffusionXLTextEncoderStep),
+    ("image_encoder", StableDiffusionXLVaeEncoderStep),
+    ("input", StableDiffusionXLInputStep),
+    ("set_timesteps", StableDiffusionXLImg2ImgSetTimestepsStep),
+    ("prepare_latents", StableDiffusionXLImg2ImgPrepareLatentsStep),
+    ("prepare_add_cond", StableDiffusionXLImg2ImgPrepareAdditionalConditioningStep),
+    ("denoise", StableDiffusionXLDenoiseStep),
+    ("decode", StableDiffusionXLDecodeStep)
+])
+```
+
+## Pipeline and block states
+
+Modular Diffusers uses *state* to communicate data between blocks. There are two types of states.
+
+- [`PipelineState`] is a global state that can be used to track all inputs and outputs across all blocks.
+- [`BlockState`] is a local view of relevant variables from [`PipelineState`] for an individual block.
+
+## Customizing blocks
+
+[Differential Diffusion](https://differential-diffusion.github.io/) differs from standard image-to-image in its `prepare_latents` and `denoise` blocks. All the other blocks can be reused, but you'll need to modify these two.
+
+Create placeholder `ModularPipelineBlocks` for `prepare_latents` and `denoise` by copying and modifying the existing ones.
+
+Print the `denoise` block to see that it is composed of [`LoopSequentialPipelineBlocks`] with three sub-blocks, `before_denoiser`, `denoiser`, and `after_denoiser`. Only the `before_denoiser` sub-block needs to be modified to prepare the latent input for the denoiser based on the change map.
+
+```py
+denoise_blocks = IMAGE2IMAGE_BLOCKS["denoise"]()
+print(denoise_blocks)
+```
+
+Replace the `StableDiffusionXLLoopBeforeDenoiser` sub-block with the new `SDXLDiffDiffLoopBeforeDenoiser` block.
+
+```py
+# Copy existing blocks as placeholders
+class SDXLDiffDiffPrepareLatentsStep(ModularPipelineBlocks):
+    """Copied from StableDiffusionXLImg2ImgPrepareLatentsStep - will modify later"""
+    # ... same implementation as StableDiffusionXLImg2ImgPrepareLatentsStep
+
+class SDXLDiffDiffDenoiseStep(StableDiffusionXLDenoiseLoopWrapper):
+    block_classes = [SDXLDiffDiffLoopBeforeDenoiser, StableDiffusionXLLoopDenoiser, StableDiffusionXLLoopAfterDenoiser]
+    block_names = ["before_denoiser", "denoiser", "after_denoiser"]
+```
+
+### prepare_latents
+
+The `prepare_latents` block requires the following changes.
+
+- a processor to process the change map
+- a new `inputs` to accept the user-provided change map, `timestep` for precomputing all the latents and `num_inference_steps` to create the mask for updating the image regions
+- update the computation in the `__call__` method for processing the change map and creating the masks, and storing it in the [`BlockState`]
+
+```diff
+class SDXLDiffDiffPrepareLatentsStep(ModularPipelineBlocks):
+    @property
+    def expected_components(self) -> List[ComponentSpec]:
+        return [
+            ComponentSpec("vae", AutoencoderKL),
+            ComponentSpec("scheduler", EulerDiscreteScheduler),
++           ComponentSpec("mask_processor", VaeImageProcessor, config=FrozenDict({"do_normalize": False, "do_convert_grayscale": True}))
+        ]
+    @property
+    def inputs(self) -> List[Tuple[str, Any]]:
+        return [
+            InputParam("generator"),
++           InputParam("diffdiff_map", required=True),
+-           InputParam("latent_timestep", required=True, type_hint=torch.Tensor),
++           InputParam("timesteps", type_hint=torch.Tensor),
++           InputParam("num_inference_steps", type_hint=int),
+        ]
+
+    @property
+    def intermediate_outputs(self) -> List[OutputParam]:
+        return [
++           OutputParam("original_latents", type_hint=torch.Tensor),
++           OutputParam("diffdiff_masks", type_hint=torch.Tensor),
+        ]
+    def __call__(self, components, state: PipelineState):
+        # ... existing logic ...
++       # Process change map and create masks
++       diffdiff_map = components.mask_processor.preprocess(block_state.diffdiff_map, height=latent_height, width=latent_width)
++       thresholds = torch.arange(block_state.num_inference_steps, dtype=diffdiff_map.dtype) / block_state.num_inference_steps
++       block_state.diffdiff_masks = diffdiff_map > (thresholds + (block_state.denoising_start or 0))
++       block_state.original_latents = block_state.latents
+```
+
+### denoise
+
+The `before_denoiser` sub-block requires the following changes.
+
+- a new `inputs` to accept a `denoising_start` parameter,  `original_latents` and `diffdiff_masks` from the `prepare_latents` block
+- update the computation in the `__call__` method for applying Differential Diffusion
+
+```diff
+class SDXLDiffDiffLoopBeforeDenoiser(ModularPipelineBlocks):
+    @property
+    def description(self) -> str:
+        return (
+            "Step within the denoising loop for differential diffusion that prepare the latent input for the denoiser"
+        )
+
+    @property
+    def inputs(self) -> List[str]:
+        return [
+            InputParam("latents", required=True, type_hint=torch.Tensor),
++           InputParam("denoising_start"),
++           InputParam("original_latents", type_hint=torch.Tensor),
++           InputParam("diffdiff_masks", type_hint=torch.Tensor),
+        ]
+
+    def __call__(self, components, block_state, i, t):
++       # Apply differential diffusion logic
++       if i == 0 and block_state.denoising_start is None:
++           block_state.latents = block_state.original_latents[:1]
++       else:
++           block_state.mask = block_state.diffdiff_masks[i].unsqueeze(0).unsqueeze(1)
++           block_state.latents = block_state.original_latents[i] * block_state.mask + block_state.latents * (1 - block_state.mask)
+
+        # ... rest of existing logic ...
+```
+
+## Assembling the blocks
+
+You should have all the blocks you need at this point to create a [`ModularPipeline`].
+
+Copy the existing `IMAGE2IMAGE_BLOCKS` preset and for the `set_timesteps` block, use the `set_timesteps` from the `TEXT2IMAGE_BLOCKS` because Differential Diffusion doesn't require a `strength` parameter.
+
+Set the `prepare_latents` and `denoise` blocks to the `SDXLDiffDiffPrepareLatentsStep` and `SDXLDiffDiffDenoiseStep` blocks you just modified.
+
+Call [`SequentialPipelineBlocks.from_blocks_dict`] on the blocks to create a `SequentialPipelineBlocks`.
+
+```py
+DIFFDIFF_BLOCKS = IMAGE2IMAGE_BLOCKS.copy()
+DIFFDIFF_BLOCKS["set_timesteps"] = TEXT2IMAGE_BLOCKS["set_timesteps"]
+DIFFDIFF_BLOCKS["prepare_latents"] = SDXLDiffDiffPrepareLatentsStep
+DIFFDIFF_BLOCKS["denoise"] = SDXLDiffDiffDenoiseStep
+
+dd_blocks = SequentialPipelineBlocks.from_blocks_dict(DIFFDIFF_BLOCKS)
+print(dd_blocks)
+```
+
+## ModularPipeline
+
+Convert the [`SequentialPipelineBlocks`] into a [`ModularPipeline`] with the [`ModularPipeline.init_pipeline`] method. This initializes the expected components to load from a `modular_model_index.json` file. Explicitly load the components by calling [`ModularPipeline.load_default_components`].
+
+It is a good idea to initialize the [`ComponentManager`] with the pipeline to help manage the different components. Once you call [`~ModularPipeline.load_default_components`], the components are registered to the [`ComponentManager`] and can be shared between workflows. The example below uses the `collection` argument to assign the components a `"diffdiff"` label for better organization.
+
+```py
+from diffusers.modular_pipelines import ComponentsManager
+
+components = ComponentManager()
+
+dd_pipeline = dd_blocks.init_pipeline("YiYiXu/modular-demo-auto", components_manager=components, collection="diffdiff")
+dd_pipeline.load_default_componenets(torch_dtype=torch.float16)
+dd_pipeline.to("cuda")
+```
+
+## Adding workflows
+
+Other workflows can be added to the [`ModularPipeline`] to support additional features without rewriting the entire pipeline from scratch.
+
+This section demonstrates how to add an IP-Adapter or ControlNet.
+
+### IP-Adapter
+
+Stable Diffusion XL already has a preset IP-Adapter block that you can use and doesn't require any changes to the existing Differential Diffusion pipeline.
+
+```py
+from diffusers.modular_pipelines.stable_diffusion_xl.encoders import StableDiffusionXLAutoIPAdapterStep
+
+ip_adapter_block = StableDiffusionXLAutoIPAdapterStep()
+```
+
+Use the [`sub_blocks.insert`] method to insert it into the [`ModularPipeline`]. The example below inserts the `ip_adapter_block` at position `0`. Print the pipeline to see that the `ip_adapter_block` is added and it requires an `ip_adapter_image`. This also added two components to the pipeline, the `image_encoder` and `feature_extractor`.
+
+```py
+dd_blocks.sub_blocks.insert("ip_adapter", ip_adapter_block, 0)
+```
+
+Call [`~ModularPipeline.init_pipeline`] to initialize a [`ModularPipeline`] and use [`~ModularPipeline.load_default_components`] to load the model components. Load and set the IP-Adapter to run the pipeline.
+
+```py
+dd_pipeline = dd_blocks.init_pipeline("YiYiXu/modular-demo-auto", collection="diffdiff")
+dd_pipeline.load_default_components(torch_dtype=torch.float16)
+dd_pipeline.loader.load_ip_adapter("h94/IP-Adapter", subfolder="sdxl_models", weight_name="ip-adapter_sdxl.bin")
+dd_pipeline.loader.set_ip_adapter_scale(0.6)
+dd_pipeline = dd_pipeline.to(device)
+
+ip_adapter_image = load_image("https://huggingface.co/datasets/YiYiXu/testing-images/resolve/main/diffdiff_orange.jpeg")
+image = load_image("https://huggingface.co/datasets/OzzyGT/testing-resources/resolve/main/differential/20240329211129_4024911930.png?download=true")
+mask = load_image("https://huggingface.co/datasets/OzzyGT/testing-resources/resolve/main/differential/gradient_mask.png?download=true")
+
+prompt = "a green pear"
+negative_prompt = "blurry"
+generator = torch.Generator(device=device).manual_seed(42)
+
+image = dd_pipeline(
+    prompt=prompt,
+    negative_prompt=negative_prompt,
+    num_inference_steps=25,
+    generator=generator,
+    ip_adapter_image=ip_adapter_image,
+    diffdiff_map=mask,
+    image=image,
+    output="images"
+)[0]
+```
+
+### ControlNet
+
+Stable Diffusion XL already has a preset ControlNet block that can readily be used.
+
+```py
+from diffusers.modular_pipelines.stable_diffusion_xl.modular_blocks import StableDiffusionXLAutoControlNetInputStep
+
+control_input_block = StableDiffusionXLAutoControlNetInputStep()
+```
+
+However, it requires modifying the `denoise` block because that's where the ControlNet injects the control information into the UNet.
+
+Modify the `denoise` block by replacing the `StableDiffusionXLLoopDenoiser` sub-block with the `StableDiffusionXLControlNetLoopDenoiser`.
+
+```py
+class SDXLDiffDiffControlNetDenoiseStep(StableDiffusionXLDenoiseLoopWrapper):
+    block_classes = [SDXLDiffDiffLoopBeforeDenoiser, StableDiffusionXLControlNetLoopDenoiser, StableDiffusionXLDenoiseLoopAfterDenoiser]
+    block_names = ["before_denoiser", "denoiser", "after_denoiser"]
+
+controlnet_denoise_block = SDXLDiffDiffControlNetDenoiseStep()
+```
+
+Insert the `controlnet_input` block and replace the `denoise` block with the new `controlnet_denoise_block`. Initialize a [`ModularPipeline`] and [`~ModularPipeline.load_default_components`] into it.
+
+```py
+dd_blocks.sub_blocks.insert("controlnet_input", control_input_block, 7)
+dd_blocks.sub_blocks["denoise"] = controlnet_denoise_block
+
+dd_pipeline = dd_blocks.init_pipeline("YiYiXu/modular-demo-auto", collection="diffdiff")
+dd_pipeline.load_default_components(torch_dtype=torch.float16)
+dd_pipeline = dd_pipeline.to(device)
+
+control_image = load_image("https://huggingface.co/datasets/YiYiXu/testing-images/resolve/main/diffdiff_tomato_canny.jpeg")
+image = load_image("https://huggingface.co/datasets/OzzyGT/testing-resources/resolve/main/differential/20240329211129_4024911930.png?download=true")
+mask = load_image("https://huggingface.co/datasets/OzzyGT/testing-resources/resolve/main/differential/gradient_mask.png?download=true")
+
+prompt = "a green pear"
+negative_prompt = "blurry"
+generator = torch.Generator(device=device).manual_seed(42)
+
+image = dd_pipeline(
+    prompt=prompt,
+    negative_prompt=negative_prompt,
+    num_inference_steps=25,
+    generator=generator,
+    control_image=control_image,
+    controlnet_conditioning_scale=0.5,
+    diffdiff_map=mask,
+    image=image,
+    output="images"
+)[0]
+```
+
+### AutoPipelineBlocks

+The Differential Diffusion, IP-Adapter, and ControlNet workflows can be bundled into a single [`ModularPipeline`] by using [`AutoPipelineBlocks`]. This allows automatically selecting which sub-blocks to run based on the inputs like `control_image` or `ip_adapter_image`. If none of these inputs are passed, then it defaults to the Differential Diffusion.
+
+Use `block_trigger_inputs` to only run the `SDXLDiffDiffControlNetDenoiseStep` block if a `control_image` input is provided. Otherwise, the `SDXLDiffDiffDenoiseStep` is used.
+
+```py
+class SDXLDiffDiffAutoDenoiseStep(AutoPipelineBlocks):
+    block_classes = [SDXLDiffDiffControlNetDenoiseStep, SDXLDiffDiffDenoiseStep]
+    block_names = ["controlnet_denoise", "denoise"]
+    block_trigger_inputs = ["controlnet_cond", None]
+```
+
+Add the `ip_adapter` and `controlnet_input` blocks.
+
+```py
+DIFFDIFF_AUTO_BLOCKS = IMAGE2IMAGE_BLOCKS.copy()
+DIFFDIFF_AUTO_BLOCKS["prepare_latents"] = SDXLDiffDiffPrepareLatentsStep
+DIFFDIFF_AUTO_BLOCKS["set_timesteps"] = TEXT2IMAGE_BLOCKS["set_timesteps"]
+DIFFDIFF_AUTO_BLOCKS["denoise"] = SDXLDiffDiffAutoDenoiseStep
+DIFFDIFF_AUTO_BLOCKS.insert("ip_adapter", StableDiffusionXLAutoIPAdapterStep, 0)
+DIFFDIFF_AUTO_BLOCKS.insert("controlnet_input",StableDiffusionXLControlNetAutoInput, 7)
+```
+
+Call [`SequentialPipelineBlocks.from_blocks_dict`] to create a [`SequentialPipelineBlocks`] and create a [`ModularPipeline`] and load in the model components to run.
+
+```py
+dd_auto_blocks = SequentialPipelineBlocks.from_blocks_dict(DIFFDIFF_AUTO_BLOCKS)
+dd_pipeline = dd_auto_blocks.init_pipeline("YiYiXu/modular-demo-auto", collection="diffdiff")
+dd_pipeline.load_default_components(torch_dtype=torch.float16)
+```
+
+## Share
+
+Add your [`ModularPipeline`] to the Hub with [`~ModularPipeline.save_pretrained`] and set `push_to_hub` argument to `True`.
+
+```py
+dd_pipeline.save_pretrained("YiYiXu/test_modular_doc", push_to_hub=True)
+```
+
+Other users can load the [`ModularPipeline`] with [`~ModularPipeline.from_pretrained`].
+

+# SequentialPipelineBlocks
+
+[`~modular_pipelines.SequentialPipelineBlocks`] are a multi-block type that composes other [`~modular_pipelines.ModularPipelineBlocks`] together in a sequence. Data flows linearly from one block to the next using `intermediate_inputs` and `intermediate_outputs`. Each block in [`~modular_pipelines.SequentialPipelineBlocks`] usually represents a step in the pipeline, and by combining them, you gradually build a pipeline.
+
+This guide shows you how to connect two blocks into a [`~modular_pipelines.SequentialPipelineBlocks`].
+
+Create two [`~modular_pipelines.ModularPipelineBlocks`]. The first block, `InputBlock`, outputs a `batch_size` value and the second block, `ImageEncoderBlock` uses `batch_size` as `intermediate_inputs`.

+# Compiling and offloading quantized models
 
 Optimizing models often involves trade-offs between [inference speed](./fp16) and [memory-usage](./memory). For instance, while [caching](./cache) can boost inference speed, it also increases memory consumption since it needs to store the outputs of intermediate attention layers. A more balanced optimization strategy combines quantizing a model, [torch.compile](./fp16#torchcompile) and various [offloading methods](./memory#offloading).
 
+> [!TIP]
+> Check the [torch.compile](./fp16#torchcompile) guide to learn more about compilation and how they can be applied here. For example, regional compilation can significantly reduce compilation time without giving up any speedups. 
+
 For image generation, combining quantization and [model offloading](./memory#model-offloading) can often give the best trade-off between quality, speed, and memory. Group offloading is not as effective for image generation because it is usually not possible to *fully* overlap data transfer if the compute kernel finishes faster. This results in some communication overhead between the CPU and GPU.
 
 For video generation, combining quantization and [group-offloading](./memory#group-offloading) tends to be better because video models are more compute-bound.

-# Quantization
+# Getting started
 
 Quantization focuses on representing data with fewer bits while also trying to preserve the precision of the original data. This often means converting a data type to represent the same information with fewer bits. For example, if your model weights are stored as 32-bit floating points and they're quantized to 16-bit floating points, this halves the model size which makes it easier to store and reduces memory usage. Lower precision can also speedup inference because it takes less time to perform calculations with fewer bits.

 ## DiffusionPipeline
 
-The [`DiffusionPipeline`] is the easiest way to use a pretrained diffusion system for inference. It is an end-to-end system containing the model and the scheduler. You can use the [`DiffusionPipeline`] out-of-the-box for many tasks. Take a look at the table below for some supported tasks, and for a complete list of supported tasks, check out the [🧨 Diffusers Summary](./api/pipelines/overview#diffusers-summary) table.
+A diffusion model combines multiple components to generate outputs in any modality based on an input, such as a text description, image or both.
 
-| **Task**                     | **Description**                                                                                              | **Pipeline**
-|------------------------------|--------------------------------------------------------------------------------------------------------------|-----------------|
-| Unconditional Image Generation          | generate an image from Gaussian noise | [unconditional_image_generation](./using-diffusers/unconditional_image_generation) |
-| Text-Guided Image Generation | generate an image given a text prompt | [conditional_image_generation](./using-diffusers/conditional_image_generation) |
-| Text-Guided Image-to-Image Translation     | adapt an image guided by a text prompt | [img2img](./using-diffusers/img2img) |
-| Text-Guided Image-Inpainting          | fill the masked part of an image given the image, the mask and a text prompt | [inpaint](./using-diffusers/inpaint) |
-| Text-Guided Depth-to-Image Translation | adapt parts of an image guided by a text prompt while preserving structure via depth estimation | [depth2img](./using-diffusers/depth2img) |
+For a standard text-to-image model:
 
-Start by creating an instance of a [`DiffusionPipeline`] and specify which pipeline checkpoint you would like to download.
-You can use the [`DiffusionPipeline`] for any [checkpoint](https://huggingface.co/models?library=diffusers&sort=downloads) stored on the Hugging Face Hub.
-In this quicktour, you'll load the [`stable-diffusion-v1-5`](https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5) checkpoint for text-to-image generation.
+1. A text encoder turns a prompt into embeddings that guide the denoising process. Some models have more than one text encoder.
+2. A scheduler contains the algorithmic specifics for gradually denoising initial random noise into clean outputs. Different schedulers affect generation speed and quality.
+3. A UNet or diffusion transformer (DiT) is the workhorse of a diffusion model.
 
-<Tip warning={true}>
+  At each step, it performs the denoising predictions, such as how much noise to remove or the general direction in which to steer the noise to generate better quality outputs.
 
-For [Stable Diffusion](https://huggingface.co/CompVis/stable-diffusion) models, please carefully read the [license](https://huggingface.co/spaces/CompVis/stable-diffusion-license) first before running the model. 🧨 Diffusers implements a [`safety_checker`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/stable_diffusion/safety_checker.py) to prevent offensive or harmful content, but the model's improved image generation capabilities can still produce potentially harmful content.
+  The UNet or DiT repeats this loop for a set amount of steps to generate the final output.
+  
+4. A variational autoencoder (VAE) encodes and decodes pixels to a spatially compressed latent-space. *Latents* are compressed representations of an image and are more efficient to work with. The UNet or DiT operates on latents, and the clean latents at the end are decoded back into images.
 
-</Tip>
+The [`DiffusionPipeline`] packages all these components into a single class for inference. There are several arguments in [`~DiffusionPipeline.__call__`] you can change, such as `num_inference_steps`, that affect the diffusion process. Try different values and arguments to see how they change generation quality or speed.
 
-Load the model with the [`~DiffusionPipeline.from_pretrained`] method:
+Load a model with [`~DiffusionPipeline.from_pretrained`] and describe what you'd like to generate. The example below uses the default argument values.
 
-```python
->>> from diffusers import DiffusionPipeline
+<hfoptions id="diffusionpipeline">
+<hfoption id="text-to-image">
 
->>> pipeline = DiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", use_safetensors=True)
-```
-
-The [`DiffusionPipeline`] downloads and caches all modeling, tokenization, and scheduling components. You'll see that the Stable Diffusion pipeline is composed of the [`UNet2DConditionModel`] and [`PNDMScheduler`] among other things:
+Use `.images[0]` to access the generated image output.
 
 ```py
->>> pipeline
-StableDiffusionPipeline {
-  "_class_name": "StableDiffusionPipeline",
-  "_diffusers_version": "0.21.4",
-  ...,
-  "scheduler": [
-    "diffusers",
-    "PNDMScheduler"
-  ],
-  ...,
-  "unet": [
-    "diffusers",
-    "UNet2DConditionModel"
-  ],
-  "vae": [
-    "diffusers",
-    "AutoencoderKL"
-  ]
-}
+import torch
+from diffusers import DiffusionPipeline
+
+pipeline = DiffusionPipeline.from_pretrained(
+  "Qwen/Qwen-Image", torch_dtype=torch.bfloat16, device_map="cuda"
+)
+
+prompt = """
+cinematic film still of a cat sipping a margarita in a pool in Palm Springs, California
+highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain
+"""
+pipeline(prompt).images[0]
 ```
 
-We strongly recommend running the pipeline on a GPU because the model consists of roughly 1.4 billion parameters.
-You can move the generator object to a GPU, just like you would in PyTorch:
+</hfoption>
+<hfoption id="text-to-video">
 
-```python
->>> pipeline.to("cuda")
-```
-
-Now you can pass a text prompt to the `pipeline` to generate an image, and then access the denoised image. By default, the image output is wrapped in a [`PIL.Image`](https://pillow.readthedocs.io/en/stable/reference/Image.html?highlight=image#the-image-class) object.
-
-```python
->>> image = pipeline("An image of a squirrel in Picasso style").images[0]
->>> image
-```
-
-<div class="flex justify-center">
-    <img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/image_of_squirrel_painting.png"/>
-</div>
-
-Save the image by calling `save`:
-
-```python
->>> image.save("image_of_squirrel_painting.png")
-```
-
-### Local pipeline
-
-You can also use the pipeline locally. The only difference is you need to download the weights first:
-
-```bash
-!git lfs install
-!git clone https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5
-```
-
-Then load the saved weights into the pipeline:
-
-```python
->>> pipeline = DiffusionPipeline.from_pretrained("./stable-diffusion-v1-5", use_safetensors=True)
-```
-
-Now, you can run the pipeline as you would in the section above.
-
-### Swapping schedulers
-
-Different schedulers come with different denoising speeds and quality trade-offs. The best way to find out which one works best for you is to try them out! One of the main features of 🧨 Diffusers is to allow you to easily switch between schedulers. For example, to replace the default [`PNDMScheduler`] with the [`EulerDiscreteScheduler`], load it with the [`~diffusers.ConfigMixin.from_config`] method:
+Use `.frames[0]` to access the generated video output and [`~utils.export_to_video`] to save the video.
 
 ```py
->>> from diffusers import EulerDiscreteScheduler
+import torch
+from diffusers import AutoencoderKLWan, DiffusionPipeline
+from diffusers.quantizers import PipelineQuantizationConfig
+from diffusers.utils import export_to_video
 
->>> pipeline = DiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", use_safetensors=True)
->>> pipeline.scheduler = EulerDiscreteScheduler.from_config(pipeline.scheduler.config)
+vae = AutoencoderKLWan.from_pretrained(
+  "Wan-AI/Wan2.2-T2V-A14B-Diffusers",
+  subfolder="vae",
+  torch_dtype=torch.float32
+)
+pipeline = DiffusionPipeline.from_pretrained(
+  "Wan-AI/Wan2.2-T2V-A14B-Diffusers",
+  vae=vae
+  torch_dtype=torch.bfloat16,
+  device_map="cuda"
+)
+
+prompt = """

 ```
 
-Try generating an image with the new scheduler and see if you notice a difference!
+</hfoption>
+</hfoptions>
 
-In the next section, you'll take a closer look at the components - the model and scheduler - that make up the [`DiffusionPipeline`] and learn how to use these components to generate an image of a cat.
+## LoRA
 
-## Models
+Adapters insert a small number of trainable parameters to the original base model. Only the inserted parameters are fine-tuned while the rest of the model weights remain frozen. This makes it fast and cheap to fine-tune a model on a new style. Among adapters, [LoRA's](./tutorials/using_peft_for_inference) are the most popular.
 
-Most models take a noisy sample, and at each timestep it predicts the *noise residual* (other models learn to predict the previous sample directly or the velocity or [`v-prediction`](https://github.com/huggingface/diffusers/blob/5e5ce13e2f89ac45a0066cb3f369462a3cf1d9ef/src/diffusers/schedulers/scheduling_ddim.py#L110)), the difference between a less noisy image and the input image. You can mix and match models to create other diffusion systems.
-
-Models are initiated with the [`~ModelMixin.from_pretrained`] method which also locally caches the model weights so it is faster the next time you load the model. For the quicktour, you'll load the [`UNet2DModel`], a basic unconditional image generation model with a checkpoint trained on cat images:
+Add a LoRA to a pipeline with the [`~loaders.QwenImageLoraLoaderMixin.load_lora_weights`] method. Some LoRA's require a special word to trigger it, such as `Realism`, in the example below. Check a LoRA's model card to see if it requires a trigger word.
 
 ```py
->>> from diffusers import UNet2DModel
+import torch
+from diffusers import DiffusionPipeline
 
->>> repo_id = "google/ddpm-cat-256"
->>> model = UNet2DModel.from_pretrained(repo_id, use_safetensors=True)
+pipeline = DiffusionPipeline.from_pretrained(
+  "Qwen/Qwen-Image", torch_dtype=torch.bfloat16, device_map="cuda"
+)
+pipeline.load_lora_weights(
+  "flymy-ai/qwen-image-realism-lora",
+)
+
+prompt = """
+super Realism cinematic film still of a cat sipping a margarita in a pool in Palm Springs in the style of umempart, California

+"""
+pipeline(prompt).images[0]
 ```
 
+Check out the [LoRA](./tutorials/using_peft_for_inference) docs or Adapters section to learn more.
+
+## Quantization
+
+[Quantization](./quantization/overview) stores data in fewer bits to reduce memory usage. It may also speed up inference because it takes less time to perform calculations with fewer bits.
+
+Diffusers provides several quantization backends and picking one depends on your use case. For example, [bitsandbytes](./quantization/bitsandbytes) and [torchao](./quantization/torchao) are both simple and easy to use for inference, but torchao supports more [quantization types](./quantization/torchao#supported-quantization-types) like fp8.
+
+Configure [`PipelineQuantizationConfig`] with the backend to use, the specific arguments (refer to the [API](./api/quantization) reference for available arguments) for that backend, and which components to quantize. The example below quantizes the model to 4-bits and only uses 14.93GB of memory.
+
+```py
+import torch
+from diffusers import DiffusionPipeline
+from diffusers.quantizers import PipelineQuantizationConfig
+
+quant_config = PipelineQuantizationConfig(
+  quant_backend="bitsandbytes_4bit",
+  quant_kwargs={"load_in_4bit": True, "bnb_4bit_quant_type": "nf4", "bnb_4bit_compute_dtype": torch.bfloat16},
+  components_to_quantize=["transformer", "text_encoder"],
+)
+pipeline = DiffusionPipeline.from_pretrained(
+  "Qwen/Qwen-Image",
+  torch_dtype=torch.bfloat16,
+  quantization_config=quant_config,
+  device_map="cuda"
+)
+
+prompt = """
+cinematic film still of a cat sipping a margarita in a pool in Palm Springs, California
+highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain
+"""
+pipeline(prompt).images[0]
+print(f"Max memory reserved: {torch.cuda.max_memory_allocated() / 1024**3:.2f} GB")
+```
+
+Take a look at the [Quantization](./quantization/overview) section for more details.
+
+## Optimizations
+
 > [!TIP]
-> Use the [`AutoModel`] API to automatically select a model class if you're unsure of which one to use.
+> Optimization is dependent on hardware specs such as memory. Use this [Space](https://huggingface.co/spaces/diffusers/optimized-diffusers-code) to generate code examples that include all of Diffusers' available memory and speed optimization techniques for any model you're using.
 
-To access the model parameters, call `model.config`:
+Modern diffusion models are very large and have billions of parameters. The iterative denoising process is also computationally intensive and slow. Diffusers provides techniques for reducing memory usage and boosting inference speed. These techniques can be combined with quantization to optimize for both memory usage and inference speed.
+
+### Memory usage
+
+The text encoders and UNet or DiT can use up as much as ~30GB of memory, exceeding the amount available on many free-tier or consumer GPUs.
+
+Offloading stores weights that aren't currently used on the CPU and only moves them to the GPU when they're needed. There are a few offloading types and the example below uses [model offloading](./optimization/memory#model-offloading). This moves an entire model, like a text encoder or transformer, to the CPU when it isn't actively being used.
+
+Call [`~DiffusionPipeline.enable_model_cpu_offload`] to activate it. By combining quantization and offloading, the following example only requires ~12.54GB of memory.
 
 ```py
->>> model.config
+import torch
+from diffusers import DiffusionPipeline
+from diffusers.quantizers import PipelineQuantizationConfig
+
+quant_config = PipelineQuantizationConfig(
+  quant_backend="bitsandbytes_4bit",
+  quant_kwargs={"load_in_4bit": True, "bnb_4bit_quant_type": "nf4", "bnb_4bit_compute_dtype": torch.bfloat16},
+  components_to_quantize=["transformer", "text_encoder"],
+)
+pipeline = DiffusionPipeline.from_pretrained(
+  "Qwen/Qwen-Image",
+  torch_dtype=torch.bfloat16,
+  quantization_config=quant_config,
+  device_map="cuda"
+)
+pipeline.enable_model_cpu_offload()
+
+prompt = """
+cinematic film still of a cat sipping a margarita in a pool in Palm Springs, California
+highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain
+"""
+pipeline(prompt).images[0]
+print(f"Max memory reserved: {torch.cuda.max_memory_allocated() / 1024**3:.2f} GB")
 ```
 
-The model configuration is a 🧊 frozen 🧊 dictionary, which means those parameters can't be changed after the model is created. This is intentional and ensures that the parameters used to define the model architecture at the start remain the same, while other parameters can still be adjusted during inference.
+Refer to the [Reduce memory usage](./optimization/memory) docs to learn more about other memory reducing techniques.
 
-Some of the most important parameters are:
+### Inference speed
 
-* `sample_size`: the height and width dimension of the input sample.
-* `in_channels`: the number of input channels of the input sample.
-* `down_block_types` and `up_block_types`: the type of down- and upsampling blocks used to create the UNet architecture.
-* `block_out_channels`: the number of output channels of the downsampling blocks; also used in reverse order for the number of input channels of the upsampling blocks.
-* `layers_per_block`: the number of ResNet blocks present in each UNet block.
+The denoising loop performs a lot of computations and can be slow. Methods like [torch.compile](./optimization/fp16#torchcompile) increases inference speed by compiling the computations into an optimized kernel. Compilation is slow for the first generation but successive generations should be much faster.
 
-To use the model for inference, create the image shape with random Gaussian noise. It should have a `batch` axis because the model can receive multiple random noises, a `channel` axis corresponding to the number of input channels, and a `sample_size` axis for the height and width of the image:
+The example below uses [regional compilation](./optimization/fp16#regional-compilation) to only compile small regions of a model. It reduces cold-start latency while also providing a runtime speed up.
+
+Call [`~ModelMixin.compile_repeated_blocks`] on the model to activate it.
 
 ```py
->>> import torch
+import torch
+from diffusers import DiffusionPipeline
 
->>> torch.manual_seed(0)
+pipeline = DiffusionPipeline.from_pretrained(
+  "Qwen/Qwen-Image", torch_dtype=torch.bfloat16, device_map="cuda"
+)
 
->>> noisy_sample = torch.randn(1, model.config.in_channels, model.config.sample_size, model.config.sample_size)
->>> noisy_sample.shape
-torch.Size([1, 3, 256, 256])
+pipeline.transformer.compile_repeated_blocks(
+    fullgraph=True,
+)
+prompt = """
+cinematic film still of a cat sipping a margarita in a pool in Palm Springs, California
+highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain
+"""
+pipeline(prompt).images[0]
 ```
 
-For inference, pass the noisy image and a `timestep` to the model. The `timestep` indicates how noisy the input image is, with more noise at the beginning and less at the end. This helps the model determine its position in the diffusion process, whether it is closer to the start or the end. Use the `sample` method to get the model output:
-
-```py
->>> with torch.no_grad():
-...     noisy_residual = model(sample=noisy_sample, timestep=2).sample
-```
-
-To generate actual examples though, you'll need a scheduler to guide the denoising process. In the next section, you'll learn how to couple a model with a scheduler.
-
-## Schedulers
-
-Schedulers manage going from a noisy sample to a less noisy sample given the model output - in this case, it is the `noisy_residual`.
-
-<Tip>
-
-🧨 Diffusers is a toolbox for building diffusion systems. While the [`DiffusionPipeline`] is a convenient way to get started with a pre-built diffusion system, you can also choose your own model and scheduler components separately to build a custom diffusion system.
-
-</Tip>
-
-For the quicktour, you'll instantiate the [`DDPMScheduler`] with its [`~diffusers.ConfigMixin.from_config`] method:
-
-```py
->>> from diffusers import DDPMScheduler
-
->>> scheduler = DDPMScheduler.from_pretrained(repo_id)
->>> scheduler
-DDPMScheduler {
-  "_class_name": "DDPMScheduler",
-  "_diffusers_version": "0.21.4",
-  "beta_end": 0.02,
-  "beta_schedule": "linear",
-  "beta_start": 0.0001,
-  "clip_sample": true,
-  "clip_sample_range": 1.0,
-  "dynamic_thresholding_ratio": 0.995,
-  "num_train_timesteps": 1000,
-  "prediction_type": "epsilon",
-  "sample_max_value": 1.0,
-  "steps_offset": 0,
-  "thresholding": false,
-  "timestep_spacing": "leading",
-  "trained_betas": null,
-  "variance_type": "fixed_small"
-}
-```
-
-<Tip>
-
-💡 Unlike a model, a scheduler does not have trainable weights and is parameter-free!
-
-</Tip>
-
-Some of the most important parameters are:
-
-* `num_train_timesteps`: the length of the denoising process or, in other words, the number of timesteps required to process random Gaussian noise into a data sample.
-* `beta_schedule`: the type of noise schedule to use for inference and training.
-* `beta_start` and `beta_end`: the start and end noise values for the noise schedule.
-
-To predict a slightly less noisy image, pass the following to the scheduler's [`~diffusers.DDPMScheduler.step`] method: model output, `timestep`, and current `sample`.
-
-```py
->>> less_noisy_sample = scheduler.step(model_output=noisy_residual, timestep=2, sample=noisy_sample).prev_sample
->>> less_noisy_sample.shape
-torch.Size([1, 3, 256, 256])
-```
-
-The `less_noisy_sample` can be passed to the next `timestep` where it'll get even less noisy! Let's bring it all together now and visualize the entire denoising process.
-
-First, create a function that postprocesses and displays the denoised image as a `PIL.Image`:
-
-```py
->>> import PIL.Image
->>> import numpy as np
-
-
->>> def display_sample(sample, i):
-...     image_processed = sample.cpu().permute(0, 2, 3, 1)
-...     image_processed = (image_processed + 1.0) * 127.5
-...     image_processed = image_processed.numpy().astype(np.uint8)
-
-...     image_pil = PIL.Image.fromarray(image_processed[0])
-...     display(f"Image at step {i}")
-...     display(image_pil)
-```
-
-To speed up the denoising process, move the input and model to a GPU:
-
-```py
->>> model.to("cuda")
->>> noisy_sample = noisy_sample.to("cuda")
-```
-
-Now create a denoising loop that predicts the residual of the less noisy sample, and computes the less noisy sample with the scheduler:
-
-```py
->>> import tqdm
-
->>> sample = noisy_sample
-
->>> for i, t in enumerate(tqdm.tqdm(scheduler.timesteps)):
-...     # 1. predict noise residual
-...     with torch.no_grad():
-...         residual = model(sample, t).sample
-
-...     # 2. compute less noisy image and set x_t -> x_t-1
-...     sample = scheduler.step(residual, t, sample).prev_sample
-
-...     # 3. optionally look at image
-...     if (i + 1) % 50 == 0:
-...         display_sample(sample, i + 1)
-```
-
-Sit back and watch as a cat is generated from nothing but noise! 😻

-# Effective and efficient diffusion

 [[open-in-colab]]
 
-Getting the [`DiffusionPipeline`] to generate images in a certain style or include what you want can be tricky. Often times, you have to run the [`DiffusionPipeline`] several times before you end up with an image you're happy with. But generating something out of nothing is a computationally intensive process, especially if you're running inference over and over again.
+# Basic performance
 
-This is why it's important to get the most *computational* (speed) and *memory* (GPU vRAM) efficiency from the pipeline to reduce the time between inference cycles so you can iterate faster.
+Diffusion is a random process that is computationally demanding. You may need to run the [`DiffusionPipeline`] several times before getting a desired output. That's why it's important to carefully balance generation speed and memory usage in order to iterate faster,
 
-This tutorial walks you through how to generate faster and better with the [`DiffusionPipeline`].
+This guide recommends some basic performance tips for using the [`DiffusionPipeline`]. Refer to the Inference Optimization section docs such as [Accelerate inference](./optimization/fp16) or [Reduce memory usage](./optimization/memory) for more detailed performance guides.
 
-Begin by loading the [`stable-diffusion-v1-5/stable-diffusion-v1-5`](https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5) model:
+## Memory usage
 
-```python
+Reducing the amount of memory used indirectly speeds up generation and can help a model fit on device.
+
+The [`~DiffusionPipeline.enable_model_cpu_offload`] method moves a model to the CPU when it is not in use to save GPU memory.

+Denoising is the most computationally demanding process during diffusion. Methods that optimizes this process accelerates inference speed. Try the following methods for a speed up.
 
-## Speed
+- Add `device_map="cuda"` to place the pipeline on a GPU. Placing a model on an accelerator, like a GPU, increases speed because it performs computations in parallel.
+- Set `torch_dtype=torch.bfloat16` to execute the pipeline in half-precision. Reducing the data type precision increases speed because it takes less time to perform computations in a lower precision.
 
-<Tip>
-
-💡 If you don't have access to a GPU, you can use one for free from a GPU provider like [Colab](https://colab.research.google.com/)!
-
-</Tip>
-
-One of the simplest ways to speed up inference is to place the pipeline on a GPU the same way you would with any PyTorch module:
-
-```python
-pipeline = pipeline.to("cuda")
-```
-
-To make sure you can use the same image and improve on it, use a [`Generator`](https://pytorch.org/docs/stable/generated/torch.Generator.html) and set a seed for [reproducibility](./using-diffusers/reusing_seeds):
-
-```python
+```py
 import torch
+import time
+from diffusers import DiffusionPipeline, DPMSolverMultistepScheduler
 
-generator = torch.Generator("cuda").manual_seed(0)
+pipeline = DiffusionPipeline.from_pretrained(
+  "stabilityai/stable-diffusion-xl-base-1.0",
+  torch_dtype=torch.bfloat16,
+  device_map="cuda
+)
 ```
 
-Now you can generate an image:
-
-```python
-image = pipeline(prompt, generator=generator).images[0]
-image
-```
-
-<div class="flex justify-center">
-    <img src="https://huggingface.co/datasets/diffusers/docs-images/resolve/main/stable_diffusion_101/sd_101_1.png">
-</div>
-
-This process took ~30 seconds on a T4 GPU (it might be faster if your allocated GPU is better than a T4). By default, the [`DiffusionPipeline`] runs inference with full `float32` precision for 50 inference steps. You can speed this up by switching to a lower precision like `float16` or running fewer inference steps.
-
-Let's start by loading the model in `float16` and generate an image:
-
-```python
-import torch
-
-pipeline = DiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.float16, use_safetensors=True)
-pipeline = pipeline.to("cuda")
-generator = torch.Generator("cuda").manual_seed(0)
-image = pipeline(prompt, generator=generator).images[0]
-image
-```
-
-<div class="flex justify-center">
-    <img src="https://huggingface.co/datasets/diffusers/docs-images/resolve/main/stable_diffusion_101/sd_101_2.png">
-</div>
-
-This time, it only took ~11 seconds to generate the image, which is almost 3x faster than before!
-
-<Tip>
-
-💡 We strongly suggest always running your pipelines in `float16`, and so far, we've rarely seen any degradation in output quality.
-
-</Tip>
-
-Another option is to reduce the number of inference steps. Choosing a more efficient scheduler could help decrease the number of steps without sacrificing output quality. You can find which schedulers are compatible with the current model in the [`DiffusionPipeline`] by calling the `compatibles` method:
-
-```python
-pipeline.scheduler.compatibles
-[
-    diffusers.schedulers.scheduling_lms_discrete.LMSDiscreteScheduler,
-    diffusers.schedulers.scheduling_unipc_multistep.UniPCMultistepScheduler,
-    diffusers.schedulers.scheduling_k_dpm_2_discrete.KDPM2DiscreteScheduler,
-    diffusers.schedulers.scheduling_deis_multistep.DEISMultistepScheduler,
-    diffusers.schedulers.scheduling_euler_discrete.EulerDiscreteScheduler,
-    diffusers.schedulers.scheduling_dpmsolver_multistep.DPMSolverMultistepScheduler,
-    diffusers.schedulers.scheduling_ddpm.DDPMScheduler,
-    diffusers.schedulers.scheduling_dpmsolver_singlestep.DPMSolverSinglestepScheduler,
-    diffusers.schedulers.scheduling_k_dpm_2_ancestral_discrete.KDPM2AncestralDiscreteScheduler,
-    diffusers.utils.dummy_torch_and_torchsde_objects.DPMSolverSDEScheduler,
-    diffusers.schedulers.scheduling_heun_discrete.HeunDiscreteScheduler,
-    diffusers.schedulers.scheduling_pndm.PNDMScheduler,
-    diffusers.schedulers.scheduling_euler_ancestral_discrete.EulerAncestralDiscreteScheduler,
-    diffusers.schedulers.scheduling_ddim.DDIMScheduler,
-]
-```
-
-The Stable Diffusion model uses the [`PNDMScheduler`] by default which usually requires ~50 inference steps, but more performant schedulers like [`DPMSolverMultistepScheduler`], require only ~20 or 25 inference steps. Use the [`~ConfigMixin.from_config`] method to load a new scheduler:
-
-```python
-from diffusers import DPMSolverMultistepScheduler
+- Use a faster scheduler, such as [`DPMSolverMultistepScheduler`], which only requires ~20-25 steps.
+- Set `num_inference_steps` to a lower value. Reducing the number of inference steps reduces the overall number of computations. However, this can result in lower generation quality.
 
+```py
 pipeline.scheduler = DPMSolverMultistepScheduler.from_config(pipeline.scheduler.config)
+
+prompt = """
+cinematic film still of a cat sipping a margarita in a pool in Palm Springs, California
+highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain
+"""
+
+start_time = time.perf_counter()
+image = pipeline(prompt).images[0]
+end_time = time.perf_counter()
+
+print(f"Image generation took {end_time - start_time:.3f} seconds")
 ```
 
-Now set the `num_inference_steps` to 20:
+## Generation quality
 
-```python
-generator = torch.Generator("cuda").manual_seed(0)
-image = pipeline(prompt, generator=generator, num_inference_steps=20).images[0]
-image
-```
+Many modern diffusion models deliver high-quality images out-of-the-box. However, you can still improve generation quality by trying the following.
 
-<div class="flex justify-center">
-    <img src="https://huggingface.co/datasets/diffusers/docs-images/resolve/main/stable_diffusion_101/sd_101_3.png">
-</div>
+- Try a more detailed and descriptive prompt. Include details such as the image medium, subject, style, and aesthetic. A negative prompt may also help by guiding a model away from undesirable features by using words like low quality or blurry.
 
-Great, you've managed to cut the inference time to just 4 seconds! ⚡️
+    ```py
+    import torch
+    from diffusers import DiffusionPipeline
 
-## Memory
+    pipeline = DiffusionPipeline.from_pretrained(
+        "stabilityai/stable-diffusion-xl-base-1.0",
+        torch_dtype=torch.bfloat16,
+        device_map="cuda"
+    )
 
-The other key to improving pipeline performance is consuming less memory, which indirectly implies more speed, since you're often trying to maximize the number of images generated per second. The easiest way to see how many images you can generate at once is to try out different batch sizes until you get an `OutOfMemoryError` (OOM).
+    prompt = """
+    cinematic film still of a cat sipping a margarita in a pool in Palm Springs, California
+    highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain
+    """
+    negative_prompt = "low quality, blurry, ugly, poor details"
+    pipeline(prompt, negative_prompt=negative_prompt).images[0]
+    ```
 
-Create a function that'll generate a batch of images from a list of prompts and `Generators`. Make sure to assign each `Generator` a seed so you can reuse it if it produces a good result.
+    For more details about creating better prompts, take a look at the [Prompt techniques](./using-diffusers/weighted_prompts) doc.
 
-```python
-def get_inputs(batch_size=1):
-    generator = [torch.Generator("cuda").manual_seed(i) for i in range(batch_size)]
-    prompts = batch_size * [prompt]
-    num_inference_steps = 20
+- Try a different scheduler, like [`HeunDiscreteScheduler`] or [`LMSDiscreteScheduler`], that gives up generation speed for quality.
 
-    return {"prompt": prompts, "generator": generator, "num_inference_steps": num_inference_steps}
-```
+    ```py
+    import torch
+    from diffusers import DiffusionPipeline, HeunDiscreteScheduler
 
-Start with `batch_size=4` and see how much memory you've consumed:
+    pipeline = DiffusionPipeline.from_pretrained(
+        "stabilityai/stable-diffusion-xl-base-1.0",
+        torch_dtype=torch.bfloat16,
+        device_map="cuda"
+    )
+    pipeline.scheduler = HeunDiscreteScheduler.from_config(pipeline.scheduler.config)
 
-```python
-from diffusers.utils import make_image_grid
-
-images = pipeline(**get_inputs(batch_size=4)).images
-make_image_grid(images, 2, 2)
-```
-
-Unless you have a GPU with more vRAM, the code above probably returned an `OOM` error! Most of the memory is taken up by the cross-attention layers. Instead of running this operation in a batch, you can run it sequentially to save a significant amount of memory. All you have to do is configure the pipeline to use the [`~DiffusionPipeline.enable_attention_slicing`] function:
-
-```python
-pipeline.enable_attention_slicing()
-```
-
-Now try increasing the `batch_size` to 8!
-
-```python
-images = pipeline(**get_inputs(batch_size=8)).images
-make_image_grid(images, rows=2, cols=4)
-```
-
-<div class="flex justify-center">
-    <img src="https://huggingface.co/datasets/diffusers/docs-images/resolve/main/stable_diffusion_101/sd_101_5.png">
-</div>
-
-Whereas before you couldn't even generate a batch of 4 images, now you can generate a batch of 8 images at ~3.5 seconds per image! This is probably the fastest you can go on a T4 GPU without sacrificing quality.
-
-## Quality
-
-In the last two sections, you learned how to optimize the speed of your pipeline by using `fp16`, reducing the number of inference steps by using a more performant scheduler, and enabling attention slicing to reduce memory consumption. Now you're going to focus on how to improve the quality of generated images.
-
-### Better checkpoints
-
-The most obvious step is to use better checkpoints. The Stable Diffusion model is a good starting point, and since its official launch, several improved versions have also been released. However, using a newer version doesn't automatically mean you'll get better results. You'll still have to experiment with different checkpoints yourself, and do a little research (such as using [negative prompts](https://minimaxir.com/2022/11/stable-diffusion-negative-prompt/)) to get the best results.
-
-As the field grows, there are more and more high-quality checkpoints finetuned to produce certain styles. Try exploring the [Hub](https://huggingface.co/models?library=diffusers&sort=downloads) and [Diffusers Gallery](https://huggingface.co/spaces/huggingface-projects/diffusers-gallery) to find one you're interested in!
-
-### Better pipeline components
-
-You can also try replacing the current pipeline components with a newer version. Let's try loading the latest [autoencoder](https://huggingface.co/stabilityai/stable-diffusion-2-1/tree/main/vae) from Stability AI into the pipeline, and generate some images:
-
-```python
-from diffusers import AutoencoderKL
-
-vae = AutoencoderKL.from_pretrained("stabilityai/sd-vae-ft-mse", torch_dtype=torch.float16).to("cuda")
-pipeline.vae = vae
-images = pipeline(**get_inputs(batch_size=8)).images
-make_image_grid(images, rows=2, cols=4)
-```
-
-<div class="flex justify-center">
-    <img src="https://huggingface.co/datasets/diffusers/docs-images/resolve/main/stable_diffusion_101/sd_101_6.png">
-</div>
-
-### Better prompt engineering
-
-The text prompt you use to generate an image is super important, so much so that it is called *prompt engineering*. Some considerations to keep during prompt engineering are:
-
-- How is the image or similar images of the one I want to generate stored on the internet?
-- What additional detail can I give that steers the model towards the style I want?
-
-With this in mind, let's improve the prompt to include color and higher quality details:
-
-```python
-prompt += ", tribal panther make up, blue on red, side profile, looking away, serious eyes"
-prompt += " 50mm portrait photography, hard rim lighting photography--beta --ar 2:3  --beta --upbeta"
-```
-
-Generate a batch of images with the new prompt:
-
-```python
-images = pipeline(**get_inputs(batch_size=8)).images
-make_image_grid(images, rows=2, cols=4)
-```
-
-<div class="flex justify-center">
-    <img src="https://huggingface.co/datasets/diffusers/docs-images/resolve/main/stable_diffusion_101/sd_101_7.png">
-</div>
-
-Pretty impressive! Let's tweak the second image - corresponding to the `Generator` with a seed of `1` - a bit more by adding some text about the age of the subject:
-
-```python
-prompts = [
-    "portrait photo of the oldest warrior chief, tribal panther make up, blue on red, side profile, looking away, serious eyes 50mm portrait photography, hard rim lighting photography--beta --ar 2:3  --beta --upbeta",
-    "portrait photo of an old warrior chief, tribal panther make up, blue on red, side profile, looking away, serious eyes 50mm portrait photography, hard rim lighting photography--beta --ar 2:3  --beta --upbeta",
-    "portrait photo of a warrior chief, tribal panther make up, blue on red, side profile, looking away, serious eyes 50mm portrait photography, hard rim lighting photography--beta --ar 2:3  --beta --upbeta",
-    "portrait photo of a young warrior chief, tribal panther make up, blue on red, side profile, looking away, serious eyes 50mm portrait photography, hard rim lighting photography--beta --ar 2:3  --beta --upbeta",
-]
-
-generator = [torch.Generator("cuda").manual_seed(1) for _ in range(len(prompts))]
-images = pipeline(prompt=prompts, generator=generator, num_inference_steps=25).images
-make_image_grid(images, 2, 2)
-```
-

 ## Next steps
 
-In this tutorial, you learned how to optimize a [`DiffusionPipeline`] for computational and memory efficiency as well as improving the quality of generated outputs. If you're interested in making your pipeline even faster, take a look at the following resources:
-
-- Learn how [PyTorch 2.0](./optimization/fp16) and [`torch.compile`](https://pytorch.org/docs/stable/generated/torch.compile.html) can yield 5 - 300% faster inference speed. On an A100 GPU, inference can be up to 50% faster!
-- If you can't use PyTorch 2, we recommend you install [xFormers](./optimization/xformers). Its memory-efficient attention mechanism works great with PyTorch 1.13.1 for faster speed and reduced memory consumption.
-- Other optimization techniques, such as model offloading, are covered in [this guide](./optimization/fp16).
+Diffusers offers more advanced and powerful optimizations such as [group-offloading](./optimization/memory#group-offloading) and [regional compilation](./optimization/fp16#regional-compilation). To learn more about how to maximize performance, take a look at the Inference Optimization section.

 ## LoRA
 
 LoRA is a training technique for significantly reducing the number of trainable parameters. As a result, training is faster and it is easier to store the resulting weights because they are a lot smaller (~100MBs). Use the [train_dreambooth_lora.py](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/train_dreambooth_lora.py) script to train with LoRA.

-# Overview
-
-Welcome to 🧨 Diffusers! If you're new to diffusion models and generative AI, and want to learn more, then you've come to the right place. These beginner-friendly tutorials are designed to provide a gentle introduction to diffusion models and help you understand the library fundamentals - the core components and how 🧨 Diffusers is meant to be used.
-
-You'll learn how to use a pipeline for inference to rapidly generate things, and then deconstruct that pipeline to really understand how to use the library as a modular toolbox for building your own diffusion systems. In the next lesson, you'll learn how to train your own diffusion model to generate what you want.
-
-After completing the tutorials, you'll have gained the necessary skills to start exploring the library on your own and see how to use it for your own projects and applications.

 There are still scenarios where recompulation is unavoidable, such as when the hotswapped LoRA targets more layers than the initial adapter. Try to load the LoRA that targets the most layers *first*. For more details about this limitation, refer to the PEFT [hotswapping](https://huggingface.co/docs/peft/main/en/package_reference/hotswap#peft.utils.hotswap.hotswap_adapter) docs.
 
+<details>
+<summary>Technical details of hotswapping</summary>
+
+The [`~loaders.lora_base.LoraBaseMixin.enable_lora_hotswap`] method converts the LoRA scaling factor from floats to torch.tensors and pads the shape of the weights to the largest required shape to avoid reassigning the whole attribute when the data in the weights are replaced.
+
+This is why the `max_rank` argument is important. The results are unchanged even when the values are padded with zeros. Computation may be slower though depending on the padding size.
+
+Since no new LoRA attributes are added, each subsequent LoRA is only allowed to target the same layers, or subset of layers, the first LoRA targets. Choosing the LoRA loading order is important because if the LoRAs target disjoint layers, you may end up creating a dummy LoRA that targets the union of all target layers.
+
+For more implementation details, take a look at the [`hotswap.py`](https://github.com/huggingface/peft/blob/92d65cafa51c829484ad3d95cf71d09de57ff066/src/peft/utils/hotswap.py) file.

 # Pipeline callbacks
 
-The denoising loop of a pipeline can be modified with custom defined functions using the `callback_on_step_end` parameter. The callback function is executed at the end of each step, and modifies the pipeline attributes and variables for the next step. This is really useful for *dynamically* adjusting certain pipeline attributes or modifying tensor variables. This versatility allows for interesting use cases such as changing the prompt embeddings at each timestep, assigning different weights to the prompt embeddings, and editing the guidance scale. With callbacks, you can implement new features without modifying the underlying code!
+A callback is a function that modifies [`DiffusionPipeline`] behavior and it is executed at the end of a denoising step. The changes are propagated to subsequent steps in the denoising process. It is useful for adjusting pipeline attributes or tensor variables to support new features without rewriting the underlying pipeline code.
 
-> [!TIP]
-> 🤗 Diffusers currently only supports `callback_on_step_end`, but feel free to open a [feature request](https://github.com/huggingface/diffusers/issues/new/choose) if you have a cool use-case and require a callback function with a different execution point!
+Diffusers provides several callbacks in the pipeline [overview](../api/pipelines/overview#callbacks).
 
-This guide will demonstrate how callbacks work by a few features you can implement with them.
+To enable a callback, configure when the callback is executed after a certain number of denoising steps with one of the following arguments.
 
-## Official callbacks
+- `cutoff_step_ratio` specifies when a callback is activated as a percentage of the total denoising steps.
+- `cutoff_step_index` specifies the exact step number a callback is activated.
 
-We provide a list of callbacks you can plug into an existing pipeline and modify the denoising loop. This is the current list of official callbacks:
+The example below uses `cutoff_step_ratio=0.4`, which means the callback is activated once denoising reaches 40% of the total inference steps. [`~callbacks.SDXLCFGCutoffCallback`] disables classifier-free guidance (CFG) after a certain number of steps, which can help save compute without significantly affecting performance.
 
-- `SDCFGCutoffCallback`: Disables the CFG after a certain number of steps for all SD 1.5 pipelines, including text-to-image, image-to-image, inpaint, and controlnet.
-- `SDXLCFGCutoffCallback`: Disables the CFG after a certain number of steps for all SDXL pipelines, including text-to-image, image-to-image, inpaint, and controlnet.
-- `IPAdapterScaleCutoffCallback`: Disables the IP Adapter after a certain number of steps for all pipelines supporting IP-Adapter.
+Define a callback with either of the `cutoff` arguments and pass it to the `callback_on_step_end` parameter in the pipeline.
 
-> [!TIP]
-> If you want to add a new official callback, feel free to open a [feature request](https://github.com/huggingface/diffusers/issues/new/choose) or [submit a PR](https://huggingface.co/docs/diffusers/main/en/conceptual/contribution#how-to-open-a-pr).
-
-To set up a callback, you need to specify the number of denoising steps after which the callback comes into effect. You can do so by using either one of these two arguments
-
-- `cutoff_step_ratio`: Float number with the ratio of the steps.
-- `cutoff_step_index`: Integer number with the exact number of the step.

Otherwise, you can also create your own callback as shown below.
 
-## Dynamic classifier-free guidance
+## Early stopping
 
-Dynamic classifier-free guidance (CFG) is a feature that allows you to disable CFG after a certain number of inference steps which can help you save compute with minimal cost to performance. The callback function for this should have the following arguments:
-
-- `pipeline` (or the pipeline instance) provides access to important properties such as `num_timesteps` and `guidance_scale`. You can modify these properties by updating the underlying attributes. For this example, you'll disable CFG by setting `pipeline._guidance_scale=0.0`.
-- `step_index` and `timestep` tell you where you are in the denoising loop. Use `step_index` to turn off CFG after reaching 40% of `num_timesteps`.
-- `callback_kwargs` is a dict that contains tensor variables you can modify during the denoising loop. It only includes variables specified in the `callback_on_step_end_tensor_inputs` argument, which is passed to the pipeline's `__call__` method. Different pipelines may use different sets of variables, so please check a pipeline's `_callback_tensor_inputs` attribute for the list of variables you can modify. Some common variables include `latents` and `prompt_embeds`. For this function, change the batch size of `prompt_embeds` after setting `guidance_scale=0.0` in order for it to work properly.
-
-Your callback function should look something like this:
-
-```python
-def callback_dynamic_cfg(pipe, step_index, timestep, callback_kwargs):
-        # adjust the batch_size of prompt_embeds according to guidance_scale
-        if step_index == int(pipeline.num_timesteps * 0.4):
-                prompt_embeds = callback_kwargs["prompt_embeds"]
-                prompt_embeds = prompt_embeds.chunk(2)[-1]
-
-                # update guidance_scale and prompt_embeds
-                pipeline._guidance_scale = 0.0
-                callback_kwargs["prompt_embeds"] = prompt_embeds
-        return callback_kwargs
-```
-
-Now, you can pass the callback function to the `callback_on_step_end` parameter and the `prompt_embeds` to `callback_on_step_end_tensor_inputs`.
+Early stopping is useful if you aren't happy with the intermediate results during generation. This callback sets a hardcoded stop point after which the pipeline terminates by setting the `_interrupt` attribute to `True`.
 
 ```py
-import torch
-from diffusers import StableDiffusionPipeline
-
-pipeline = StableDiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", torch_dtype=torch.float16)
-pipeline = pipeline.to("cuda")
-
-prompt = "a photo of an astronaut riding a horse on mars"
-
-generator = torch.Generator(device="cuda").manual_seed(1)
-out = pipeline(
-    prompt,
-    generator=generator,
-    callback_on_step_end=callback_dynamic_cfg,
-    callback_on_step_end_tensor_inputs=['prompt_embeds']
-)
-
-out.images[0].save("out_custom_cfg.png")
-```
-
-## Interrupt the diffusion process
-
-> [!TIP]
-> The interruption callback is supported for text-to-image, image-to-image, and inpainting for the [StableDiffusionPipeline](../api/pipelines/stable_diffusion/overview) and [StableDiffusionXLPipeline](../api/pipelines/stable_diffusion/stable_diffusion_xl).
-
-Stopping the diffusion process early is useful when building UIs that work with Diffusers because it allows users to stop the generation process if they're unhappy with the intermediate results. You can incorporate this into your pipeline with a callback.
-
-This callback function should take the following arguments: `pipeline`, `i`, `t`, and `callback_kwargs` (this must be returned). Set the pipeline's `_interrupt` attribute to `True` to stop the diffusion process after a certain number of steps. You are also free to implement your own custom stopping logic inside the callback.
-
-In this example, the diffusion process is stopped after 10 steps even though `num_inference_steps` is set to 50.
-
-```python
-from diffusers import StableDiffusionPipeline
-
-pipeline = StableDiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5")

-## IP Adapter Cutoff
+## Display intermediate images
 
-IP Adapter is an image prompt adapter that can be used for diffusion models without any changes to the underlying model. We can use the IP Adapter Cutoff Callback to disable the IP Adapter after a certain number of steps. To set up the callback, you need to specify the number of denoising steps after which the callback comes into effect. You can do so by using either one of these two arguments:
+Visualizing the intermediate images is useful for progress monitoring and assessing the quality of the generated content. This callback decodes the latent tensors at each step and converts them to images.
 
-- `cutoff_step_ratio`: Float number with the ratio of the steps.
-- `cutoff_step_index`: Integer number with the exact number of the step.

-## Community pipelines
+# Community pipelines and components
 
-> [!TIP] Take a look at GitHub Issue [#841](https://github.com/huggingface/diffusers/issues/841) for more context about why we're adding community pipelines to help everyone easily share their work without being slowed down.
-
-Community pipelines are any [`DiffusionPipeline`] class that are different from the original paper implementation (for example, the [`StableDiffusionControlNetPipeline`] corresponds to the [Text-to-Image Generation with ControlNet Conditioning](https://huggingface.co/papers/2302.05543) paper). They provide additional functionality or extend the original implementation of a pipeline.
-
-There are many cool community pipelines like [Marigold Depth Estimation](https://github.com/huggingface/diffusers/tree/main/examples/community#marigold-depth-estimation) or [InstantID](https://github.com/huggingface/diffusers/tree/main/examples/community#instantid-pipeline), and you can find all the official community pipelines [here](https://github.com/huggingface/diffusers/tree/main/examples/community).
-
-There are two types of community pipelines, those stored on the Hugging Face Hub and those stored on Diffusers GitHub repository. Hub pipelines are completely customizable (scheduler, models, pipeline code, etc.) while Diffusers GitHub pipelines are only limited to custom pipeline code.
-

-pipeline = DiffusionPipeline.from_pretrained(
-    "stable-diffusion-v1-5/stable-diffusion-v1-5",
-    custom_pipeline="clip_guided_stable_diffusion",
-    custom_revision="v0.25.0",

-```
-
-</hfoption>
-</hfoptions>
-
-### Load with from_pipe
-
-Community pipelines can also be loaded with the [`~DiffusionPipeline.from_pipe`] method which allows you to load and reuse multiple pipelines without any additional memory overhead (learn more in the [Reuse a pipeline](./loading#reuse-a-pipeline) guide). The memory requirement is determined by the largest single pipeline loaded.
-
-For example, let's load a community pipeline that supports [long prompts with weighting](https://github.com/huggingface/diffusers/tree/main/examples/community#long-prompt-weighting-stable-diffusion) from a Stable Diffusion pipeline.
-
-```py
-import torch

-## Example community pipelines
-
-Community pipelines are a really fun and creative way to extend the capabilities of the original pipeline with new and unique features. You can find all community pipelines in the [diffusers/examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) folder with inference and training examples for how to use them.
-
-This section showcases a couple of the community pipelines and hopefully it'll inspire you to create your own (feel free to open a PR for your community pipeline and ping us for a review)!
+Community pipelines are [`DiffusionPipeline`] classes that are different from the original paper implementation. They provide additional functionality or extend the original pipeline implementation.
 
 > [!TIP]
-> The [`~DiffusionPipeline.from_pipe`] method is particularly useful for loading community pipelines because many of them don't have pretrained weights and add a feature on top of an existing pipeline like Stable Diffusion or Stable Diffusion XL. You can learn more about the [`~DiffusionPipeline.from_pipe`] method in the [Load with from_pipe](custom_pipeline_overview#load-with-from_pipe) section.
+> Check out the community pipelines in [diffusers/examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) with inference and training examples for how to use them.
 
-<hfoptions id="community">
-<hfoption id="Marigold">
+Community pipelines are either stored on the Hub or the Diffusers' GitHub repository. Hub pipelines are completely customizable (scheduler, models, pipeline code, etc.) while GitHub pipelines are limited to only the custom pipeline code. Further compare the two community pipeline types in the table below.
 
-[Marigold](https://marigoldmonodepth.github.io/) is a depth estimation diffusion pipeline that uses the rich existing and inherent visual knowledge in diffusion models. It takes an input image and denoises and decodes it into a depth map. Marigold performs well even on images it hasn't seen before.

+| Usage | Same. | Same. |
+| Review process | Open a Pull Request on GitHub and undergo a review process from the Diffusers team before merging. This option is slower. | Upload directly to a Hub repository without a review. This is the fastest option. |
+| Visibility | Included in the official Diffusers repository and docs. | Included on your Hub profile and relies on your own usage and promotion to gain visibility. |

+There are a few ways to load a community pipeline.
+
+- Pass a path to `custom_pipeline` to load a local community pipeline. The directory must contain a `pipeline.py` file containing the pipeline class.
+
+  ```py
+  import torch
+  from diffusers import DiffusionPipeline
+
+  pipeline = DiffusionPipeline.from_pretrained(
+      "stabilityai/stable-diffusion-3-medium-diffusers",
+      custom_pipeline="path/to/pipeline_directory",
+      torch_dtype=torch.float16,
+      device_map="cuda"
+  )
+  ```
+
+- The `custom_pipeline` argument is also supported by [`~DiffusionPipeline.from_pipe`], which is useful for [reusing pipelines](./loading#reuse-a-pipeline) without using additional memory. It limits the memory usage to only the largest pipeline loaded.
+
+  ```py
+  import torch
+  from diffusers import DiffusionPipeline
+
+  pipeline_sd = DiffusionPipeline.from_pretrained("emilianJR/CyberRealistic_V3", torch_dtype=torch.float16, device_map="cuda")
+  pipeline_lpw = DiffusionPipeline.from_pipe(
+      pipeline_sd, custom_pipeline="lpw_stable_diffusion", device_map="cuda"
+  )
+  ```
+
+  The [`~DiffusionPipeline.from_pipe`] method is especially useful for loading community pipelines because many of them don't have pretrained weights. Community pipelines generally add a feature on top of an existing pipeline.
 
 ## Community components
 
-Community components allow users to build pipelines that may have customized components that are not a part of Diffusers. If your pipeline has custom components that Diffusers doesn't already support, you need to provide their implementations as Python modules. These customized components could be a VAE, UNet, and scheduler. In most cases, the text encoder is imported from the Transformers library. The pipeline code itself can also be customized.
+Community components let users build pipelines with custom transformers, UNets, VAEs, and schedulers not supported by Diffusers. These components require Python module implementations. 
 
-This section shows how users should use community components to build a community pipeline.
+This section shows how users can use community components to build a community pipeline using [showlab/show-1-base](https://huggingface.co/showlab/show-1-base) as an example.
 
-You'll use the [showlab/show-1-base](https://huggingface.co/showlab/show-1-base) pipeline checkpoint as an example.
-
-1. Import and load the text encoder from Transformers:
-
-```python
-from transformers import T5Tokenizer, T5EncoderModel
-
-pipe_id = "showlab/show-1-base"
-tokenizer = T5Tokenizer.from_pretrained(pipe_id, subfolder="tokenizer")
-text_encoder = T5EncoderModel.from_pretrained(pipe_id, subfolder="text_encoder")
-```
-
-2. Load a scheduler:
+1. Load the required components, the scheduler and image processor. The text encoder is generally imported from [Transformers](https://huggingface.co/docs/transformers/index).
 
 ```python
+from transformers import T5Tokenizer, T5EncoderModel, CLIPImageProcessor
 from diffusers import DPMSolverMultistepScheduler
 
+pipeline_id = "showlab/show-1-base"
+tokenizer = T5Tokenizer.from_pretrained(pipeline_id, subfolder="tokenizer")
+text_encoder = T5EncoderModel.from_pretrained(pipeline_id, subfolder="text_encoder")
 scheduler = DPMSolverMultistepScheduler.from_pretrained(pipe_id, subfolder="scheduler")
-```
-
-3. Load an image processor:

-
 feature_extractor = CLIPImageProcessor.from_pretrained(pipe_id, subfolder="feature_extractor")
 ```

-
-4. Now you'll load a [custom UNet](https://github.com/showlab/Show-1/blob/main/showone/models/unet_3d_condition.py), which in this example, has already been implemented in [showone_unet_3d_condition.py](https://huggingface.co/sayakpaul/show-1-base-with-code/blob/main/unet/showone_unet_3d_condition.py) for your convenience. You'll notice the [`UNet3DConditionModel`] class name is changed to `ShowOneUNet3DConditionModel` because [`UNet3DConditionModel`] already exists in Diffusers. Any components needed for the `ShowOneUNet3DConditionModel` class should be placed in showone_unet_3d_condition.py.

-5. Finally, you'll load the custom pipeline code. For this example, it has already been created for you in [pipeline_t2v_base_pixel.py](https://huggingface.co/sayakpaul/show-1-base-with-code/blob/main/pipeline_t2v_base_pixel.py). This script contains a custom `TextToVideoIFPipeline` class for generating videos from text. Just like the custom UNet, any code needed for the custom pipeline to work should go in pipeline_t2v_base_pixel.py.

-Diffusion systems consist of multiple components like parameterized models and schedulers that interact in complex ways. That is why we designed the [`DiffusionPipeline`] to wrap the complexity of the entire diffusion system into an easy-to-use API. At the same time, the [`DiffusionPipeline`] is entirely customizable so you can modify each component to build a diffusion system for your use case.
+# DiffusionPipeline
 
-This guide will show you how to load:
+Diffusion models consists of multiple components like UNets or diffusion transformers (DiTs), text encoders, variational autoencoders (VAEs), and schedulers. The [`DiffusionPipeline`] wraps all of these components into a single easy-to-use API without giving up the flexibility to modify it's components.
 
-- pipelines from the Hub and locally
-- different components into a pipeline
-- multiple pipelines without increasing memory usage
-- checkpoint variants such as different floating point types or non-exponential mean averaged (EMA) weights
+This guide will show you how to load a [`DiffusionPipeline`].
 
-## Load a pipeline
+## Loading a pipeline
 
-> [!TIP]
-> Skip to the [DiffusionPipeline explained](#diffusionpipeline-explained) section if you're interested in an explanation about how the [`DiffusionPipeline`] class works.
+[`DiffusionPipeline`] is a base pipeline class that automatically selects and returns an instance of a model's pipeline subclass, like [`QwenImagePipeline`], by scanning the `model_index.json` file for the class name.
 
-There are two ways to load a pipeline for a task:
-
-1. Load the generic [`DiffusionPipeline`] class and allow it to automatically detect the correct pipeline class from the checkpoint.
-2. Load a specific pipeline class for a specific task.
-
-<hfoptions id="pipelines">
-<hfoption id="generic pipeline">
-
-The [`DiffusionPipeline`] class is a simple and generic way to load the latest trending diffusion model from the [Hub](https://huggingface.co/models?library=diffusers&sort=trending). It uses the [`~DiffusionPipeline.from_pretrained`] method to automatically detect the correct pipeline class for a task from the checkpoint, downloads and caches all the required configuration and weight files, and returns a pipeline ready for inference.
-
-```python
-from diffusers import DiffusionPipeline
-
-pipeline = DiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", use_safetensors=True)
-```
-
-This same checkpoint can also be used for an image-to-image task. The [`DiffusionPipeline`] class can handle any task as long as you provide the appropriate inputs. For example, for an image-to-image task, you need to pass an initial image to the pipeline.
+Pass a model id to [`~DiffusionPipeline.from_pretrained`] to load a pipeline.
 
 ```py
+import torch
 from diffusers import DiffusionPipeline
 
-pipeline = DiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", use_safetensors=True)
+pipeline = DiffusionPipeline.from_pretrained(
+  "Qwen/Qwen-Image", torch_dtype=torch.bfloat16, device_map="cuda"
+)
+```
 
-init_image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/img2img-init.png")
-prompt = "Astronaut in a jungle, cold color palette, muted colors, detailed, 8k"
-image = pipeline("Astronaut in a jungle, cold color palette, muted colors, detailed, 8k", image=init_image).images[0]
+Every model has a specific pipeline subclass that inherits from [`DiffusionPipeline`]. A subclass usually has a narrow focus and are task-specific. See the table below for an example.
+
+| pipeline subclass | task |
+|---|---|
+| [`QwenImagePipeline`] | text-to-image |
+| [`QwenImageImg2ImgPipeline`] | image-to-image |
+| [`QwenImageInpaintPipeline`] | inpaint |
+
+You could use the subclass directly by passing a model id to [`~QwenImagePipeline.from_pretrained`].
+
+```py
+import torch
+from diffusers import QwenImagePipeline
+
+pipeline = QwenImagePipeline.from_pretrained(
+  "Qwen/Qwen-Image", torch_dtype=torch.bfloat16, device_map="cuda"
+)
+```
+
+### Local pipelines
+
+Pipelines can also be run locally. Use [`~huggingface_hub.snapshot_download`] to download a model repository.
+
+```py
+from huggingface_hub import snapshot_download
+
+snapshot_download(repo_id="Qwen/Qwen-Image")
+```
+
+The model is downloaded to your [cache](../installation#cache). Pass the folder path to [`~QwenImagePipeline.from_pretrained`] to load it.
+
+```py
+import torch
+from diffusers import QwenImagePipeline
+
+pipeline = QwenImagePipeline.from_pretrained(
+  "path/to/your/cache", torch_dtype=torch.bfloat16, device_map="cuda"
+)
+```
+
+The [`~QwenImagePipeline.from_pretrained`] method won't download files from the Hub when it detects a local path. But this also means it won't download and cache any updates that have been made to the model either.
+
+## Pipeline data types
+
+Use the `torch_dtype` argument in [`~DiffusionPipeline.from_pretrained`] to load a model with a specific data type. This allows you to load different models in different precisions. For example, loading a large transformer model in half-precision reduces the memory required.
+
+Pass the data type for each model as a dictionary to `torch_dtype`. Use the `default` key to set the default data type. If a model isn't in the dictionary and `default` isn't provided, it is loaded in full precision (`torch.float32`).
+
+```py
+import torch
+from diffusers import QwenImagePipeline
+
+pipeline = QwenImagePipeline.from_pretrained(
+  "Qwen/Qwen-Image",
+  torch_dtype={"transformer": torch.bfloat16, "default": torch.float16},
+)
+print(pipeline.transformer.dtype, pipeline.vae.dtype)
+```
+
+You don't need to use a dictionary if you're loading all the models in the same data type.
+
+```py
+import torch
+from diffusers import QwenImagePipeline
+
+pipeline = QwenImagePipeline.from_pretrained(
+  "Qwen/Qwen-Image", torch_dtype=torch.bfloat16
+)
+print(pipeline.transformer.dtype, pipeline.vae.dtype)
+```
+
+## Device placement
+
+The `device_map` argument determines individual model or pipeline placement on an accelerator like a GPU. It is especially helpful when there are multiple GPUs.
+
+Diffusers currently provides three options to `device_map`, `"cuda"`, `"balanced"` and `"auto"`. Refer to the table below to compare the three placement strategies.
+
+| parameter | description |
+|---|---|
+| `"cuda"` | places model or pipeline on CUDA device |
+| `"balanced"` | evenly distributes model or pipeline on all GPUs |
+| `"auto"` | distribute model from fastest device first to slowest |
+
+Use the `max_memory` argument in [`~DiffusionPipeline.from_pretrained`] to allocate a maximum amount of memory to use on each device. By default, Diffusers uses the maximum amount available.

-### Specifying Component-Specific Data Types
+Reset a pipeline's `device_map` with the [`~DiffusionPipeline.reset_device_map`] method. This is necessary if you want to use methods such as `.to()`, [`~DiffusionPipeline.enable_sequential_cpu_offload`], and [`~DiffusionPipeline.enable_model_cpu_offload`].
 
-You can customize the data types for individual sub-models by passing a dictionary to the `torch_dtype` parameter. This allows you to load different components of a pipeline in different floating point precisions. For instance, if you want to load the transformer with `torch.bfloat16` and all other components with `torch.float16`, you can pass a dictionary mapping:
+```py
+pipeline.reset_device_map()
+```
 
-```python
-from diffusers import HunyuanVideoPipeline
+## Parallel loading
+
+Large models are often [sharded](../training/distributed_inference#model-sharding) into smaller files so that they are easier to load. Diffusers supports loading shards in parallel to speed up the loading process.
+
+Set `HF_ENABLE_PARALLEL_LOADING` to `"YES"` to enable parallel loading of shards.
+
+The `device_map` argument should be set to `"cuda"` to pre-allocate a large chunk of memory based on the model size. This substantially reduces model load time because warming up the memory allocator now avoids many smaller calls to the allocator later.
+
+```py
+import os
 import torch
-
-pipe = HunyuanVideoPipeline.from_pretrained(
-    "hunyuanvideo-community/HunyuanVideo",
-    torch_dtype={"transformer": torch.bfloat16, "default": torch.float16},
-)
-print(pipe.transformer.dtype, pipe.vae.dtype)  # (torch.bfloat16, torch.float16)
-```
-
-If a component is not explicitly specified in the dictionary and no `default` is provided, it will be loaded with `torch.float32`.
-
-### Local pipeline
-
-To load a pipeline locally, use [git-lfs](https://git-lfs.github.com/) to manually download a checkpoint to your local disk.
-
-```bash
-git-lfs install
-git clone https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5
-```
-
-This creates a local folder, ./stable-diffusion-v1-5, on your disk and you should pass its path to [`~DiffusionPipeline.from_pretrained`].
-
-```python
 from diffusers import DiffusionPipeline
 
-stable_diffusion = DiffusionPipeline.from_pretrained("./stable-diffusion-v1-5", use_safetensors=True)
+os.environ["HF_ENABLE_PARALLEL_LOADING"] = "YES"
+
+pipeline = DiffusionPipeline.from_pretrained(
+  "Wan-AI/Wan2.2-I2V-A14B-Diffusers", torch_dtype=torch.bfloat16, device_map="cuda"
+)
 ```
 
-The [`~DiffusionPipeline.from_pretrained`] method won't download files from the Hub when it detects a local path, but this also means it won't download and cache the latest changes to a checkpoint.
+## Replacing models in a pipeline
 
-## Customize a pipeline
+[`DiffusionPipeline`] is flexible and accommodates loading different models or schedulers. You can experiment with different schedulers to optimize for generation speed or quality, and you can replace models with more performant ones.
 
-You can customize a pipeline by loading different components into it. This is important because you can:
-
-- change to a scheduler with faster generation speed or higher generation quality depending on your needs (call the `scheduler.compatibles` method on your pipeline to see compatible schedulers)
-- change a default pipeline component to a newer and better performing one
-
-For example, let's customize the default [stabilityai/stable-diffusion-xl-base-1.0](https://hf.co/stabilityai/stable-diffusion-xl-base-1.0) checkpoint with:
-
-- The [`HeunDiscreteScheduler`] to generate higher quality images at the expense of slower generation speed. You must pass the `subfolder="scheduler"` parameter in [`~HeunDiscreteScheduler.from_pretrained`] to load the scheduler configuration into the correct [subfolder](https://hf.co/stabilityai/stable-diffusion-xl-base-1.0/tree/main/scheduler) of the pipeline repository.
-- A more stable VAE that runs in fp16.
+The example below swaps the default scheduler to generate higher quality images and a more stable VAE version. Pass the `subfolder` argument in [`~HeunDiscreteScheduler.from_pretrained`] to load the scheduler to the correct subfolder.
 
 ```py
-from diffusers import StableDiffusionXLPipeline, HeunDiscreteScheduler, AutoencoderKL
 import torch
+from diffusers import DiffusionPipeline, HeunDiscreteScheduler, AutoModel
 
-scheduler = HeunDiscreteScheduler.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="scheduler")
-vae = AutoencoderKL.from_pretrained("madebyollin/sdxl-vae-fp16-fix", torch_dtype=torch.float16, use_safetensors=True)
-```
+scheduler = HeunDiscreteScheduler.from_pretrained(
+  "stabilityai/stable-diffusion-xl-base-1.0", subfolder="scheduler"
+)
+vae = AutoModel.from_pretrained(
+  "madebyollin/sdxl-vae-fp16-fix", torch_dtype=torch.float16
+)
 
-Now pass the new scheduler and VAE to the [`StableDiffusionXLPipeline`].
-
-```py
-pipeline = StableDiffusionXLPipeline.from_pretrained(
+pipeline = DiffusionPipeline.from_pretrained(
   "stabilityai/stable-diffusion-xl-base-1.0",
   scheduler=scheduler,
   vae=vae,
   torch_dtype=torch.float16,
-  variant="fp16",
-  use_safetensors=True
-).to("cuda")
+  device_map="cuda"
+)
 ```
 
-## Reuse a pipeline
+## Reusing models in multiple pipelines
 
-When you load multiple pipelines that share the same model components, it makes sense to reuse the shared components instead of reloading everything into memory again, especially if your hardware is memory-constrained. For example:
+When working with multiple pipelines that use the same model, the [`~DiffusionPipeline.from_pipe`] method enables reusing a model instead of reloading it each time. This allows you to use multiple pipelines without increasing memory usage.
 
-1. You generated an image with the [`StableDiffusionPipeline`] but you want to improve its quality with the [`StableDiffusionSAGPipeline`]. Both of these pipelines share the same pretrained model, so it'd be a waste of memory to load the same model twice.
-2. You want to add a model component, like a [`MotionAdapter`](../api/pipelines/animatediff#animatediffpipeline), to [`AnimateDiffPipeline`] which was instantiated from an existing [`StableDiffusionPipeline`]. Again, both pipelines share the same pretrained model, so it'd be a waste of memory to load an entirely new pipeline again.
+Memory usage is determined by the pipeline with the highest memory requirement regardless of the number of pipelines.
 
-With the [`DiffusionPipeline.from_pipe`] API, you can switch between multiple pipelines to take advantage of their different features without increasing memory-usage. It is similar to turning on and off a feature in your pipeline.
-
-> [!TIP]
-> To switch between tasks (rather than features), use the [`~DiffusionPipeline.from_pipe`] method with the [AutoPipeline](../api/pipelines/auto_pipeline) class, which automatically identifies the pipeline class based on the task (learn more in the [AutoPipeline](../tutorials/autopipeline) tutorial).
-
-Let's start with a [`StableDiffusionPipeline`] and then reuse the loaded model components to create a [`StableDiffusionSAGPipeline`] to increase generation quality. You'll use the [`StableDiffusionPipeline`] with an [IP-Adapter](./ip_adapter) to generate a bear eating pizza.
-
-```python
-from diffusers import DiffusionPipeline, StableDiffusionSAGPipeline
-import torch
-import gc
-from diffusers.utils import load_image
-from accelerate.utils import compute_module_sizes
-
-image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/load_neg_embed.png")
-
-pipe_sd = DiffusionPipeline.from_pretrained("SG161222/Realistic_Vision_V6.0_B1_noVAE", torch_dtype=torch.float16)
-pipe_sd.load_ip_adapter("h94/IP-Adapter", subfolder="models", weight_name="ip-adapter_sd15.bin")
-pipe_sd.set_ip_adapter_scale(0.6)
-pipe_sd.to("cuda")
-
-generator = torch.Generator(device="cpu").manual_seed(33)
-out_sd = pipe_sd(
-    prompt="bear eats pizza",
-    negative_prompt="wrong white balance, dark, sketches,worst quality,low quality",
-    ip_adapter_image=image,
-    num_inference_steps=50,
-    generator=generator,
-).images[0]
-out_sd
-```
-
-<div class="flex justify-center">
-  <img class="rounded-xl" src="https://huggingface.co/datasets/YiYiXu/testing-images/resolve/main/from_pipe_out_sd_0.png"/>
-</div>
-
-For reference, you can check how much memory this process consumed.
-
-```python
-def bytes_to_giga_bytes(bytes):
-    return bytes / 1024 / 1024 / 1024
-print(f"Max memory allocated: {bytes_to_giga_bytes(torch.cuda.max_memory_allocated())} GB")
-"Max memory allocated: 4.406213283538818 GB"
-```
-
-Now, reuse the same pipeline components from [`StableDiffusionPipeline`] in [`StableDiffusionSAGPipeline`] with the [`~DiffusionPipeline.from_pipe`] method.
+The example below loads a pipeline and then loads a second pipeline with [`~DiffusionPipeline.from_pipe`] to use [perturbed-attention guidance (PAG)](../api/pipelines/pag) to improve generation quality.
 
 > [!WARNING]
-> Some pipeline methods may not function properly on new pipelines created with [`~DiffusionPipeline.from_pipe`]. For instance, the [`~DiffusionPipeline.enable_model_cpu_offload`] method installs hooks on the model components based on a unique offloading sequence for each pipeline. If the models are executed in a different order in the new pipeline, the CPU offloading may not work correctly.
->
-> To ensure everything works as expected, we recommend re-applying a pipeline method on a new pipeline created with [`~DiffusionPipeline.from_pipe`].
+> Use [`AutoPipelineForText2Image`] because [`DiffusionPipeline`] doesn't support PAG. Refer to the [AutoPipeline](../tutorials/autopipeline) docs to learn more. 
 
-```python
-pipe_sag = StableDiffusionSAGPipeline.from_pipe(
-    pipe_sd
+```py
+import torch
+from diffusers import AutoPipelineForText2Image
+
+pipeline_sdxl = AutoPipelineForText2Image.from_pretrained(

-  <img class="rounded-xl" src="https://huggingface.co/datasets/YiYiXu/testing-images/resolve/main/from_pipe_out_sag_1.png"/>
-</div>
-
-If you check the memory usage, you'll see it remains the same as before because [`StableDiffusionPipeline`] and [`StableDiffusionSAGPipeline`] are sharing the same pipeline components. This allows you to use them interchangeably without any additional memory overhead.
+Set `enable_pag=True` in the second pipeline to enable PAG. The second pipeline uses the same amount of memory because it shares model weights with the first one.
 
 ```py
-print(f"Max memory allocated: {bytes_to_giga_bytes(torch.cuda.max_memory_allocated())} GB")
-"Max memory allocated: 4.406213283538818 GB"
+pipeline = AutoPipelineForText2Image.from_pipe(
+  pipeline_sdxl, enable_pag=True
+)

+print(f"Max memory reserved: {torch.cuda.max_memory_allocated() / 1024**3:.2f} GB")
+# Max memory reserved: 10.47 GB
 ```
 
-Let's animate the image with the [`AnimateDiffPipeline`] and also add a [`MotionAdapter`] module to the pipeline. For the [`AnimateDiffPipeline`], you need to unload the IP-Adapter first and reload it *after* you've created your new pipeline (this only applies to the [`AnimateDiffPipeline`]).
+> [!WARNING]
+> Pipelines created by [`~DiffusionPipeline.from_pipe`] share the same models and *state*. Modifying the state of a model in one pipeline affects all the other pipelines that share the same model.
 
-```py
-from diffusers import AnimateDiffPipeline, MotionAdapter, DDIMScheduler
-from diffusers.utils import export_to_gif
-
-pipe_sag.unload_ip_adapter()
-adapter = MotionAdapter.from_pretrained("guoyww/animatediff-motion-adapter-v1-5-2", torch_dtype=torch.float16)
-
-pipe_animate = AnimateDiffPipeline.from_pipe(pipe_sd, motion_adapter=adapter)
-pipe_animate.scheduler = DDIMScheduler.from_config(pipe_animate.scheduler.config, beta_schedule="linear")
-# load IP-Adapter and LoRA weights again
-pipe_animate.load_ip_adapter("h94/IP-Adapter", subfolder="models", weight_name="ip-adapter_sd15.bin")
-pipe_animate.load_lora_weights("guoyww/animatediff-motion-lora-zoom-out", adapter_name="zoom-out")
-pipe_animate.to("cuda")
-
-generator = torch.Generator(device="cpu").manual_seed(33)
-pipe_animate.set_adapters("zoom-out", adapter_weights=0.75)
-out = pipe_animate(
-    prompt="bear eats pizza",

-</div>
-
-The [`AnimateDiffPipeline`] is more memory-intensive and consumes 15GB of memory (see the [Memory-usage of from_pipe](#memory-usage-of-from_pipe) section to learn what this means for your memory-usage).
-
-```py
-print(f"Max memory allocated: {bytes_to_giga_bytes(torch.cuda.max_memory_allocated())} GB")
-"Max memory allocated: 15.178664207458496 GB"
-```
-
-### Modify from_pipe components
-
-Pipelines loaded with [`~DiffusionPipeline.from_pipe`] can be customized with different model components or methods. However, whenever you modify the *state* of the model components, it affects all the other pipelines that share the same components. For example, if you call [`~diffusers.loaders.IPAdapterMixin.unload_ip_adapter`] on the [`StableDiffusionSAGPipeline`], you won't be able to use IP-Adapter with the [`StableDiffusionPipeline`] because it's been removed from their shared components.
-
-```py
-pipe.sag_unload_ip_adapter()
-
-generator = torch.Generator(device="cpu").manual_seed(33)
-out_sd = pipe_sd(
-    prompt="bear eats pizza",
-    negative_prompt="wrong white balance, dark, sketches,worst quality,low quality",
-    ip_adapter_image=image,
-    num_inference_steps=50,
-    generator=generator,
-).images[0]
-"AttributeError: 'NoneType' object has no attribute 'image_projection_layers'"
-```
-
-### Memory usage of from_pipe
-
-The memory requirement of loading multiple pipelines with [`~DiffusionPipeline.from_pipe`] is determined by the pipeline with the highest memory-usage regardless of the number of pipelines you create.
-
-| Pipeline | Memory usage (GB) |
-|---|---|
-| StableDiffusionPipeline | 4.400 |
-| StableDiffusionSAGPipeline | 4.400 |
-| AnimateDiffPipeline | 15.178 |
-
-The [`AnimateDiffPipeline`] has the highest memory requirement, so the *total memory-usage* is based only on the [`AnimateDiffPipeline`]. Your memory-usage will not increase if you create additional pipelines as long as their memory requirements doesn't exceed that of the [`AnimateDiffPipeline`]. Each pipeline can be used interchangeably without any additional memory overhead.
+Some methods may not work correctly on pipelines created with [`~DiffusionPipeline.from_pipe`]. For example, [`~DiffusionPipeline.enable_model_cpu_offload`] relies on a unique model execution order, which may differ in the new pipeline. To ensure proper functionality, reapply these methods on the new pipeline.
 
 ## Safety checker
 
-Diffusers implements a [safety checker](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/stable_diffusion/safety_checker.py) for Stable Diffusion models which can generate harmful content. The safety checker screens the generated output against known hardcoded not-safe-for-work (NSFW) content. If for whatever reason you'd like to disable the safety checker, pass `safety_checker=None` to the [`~DiffusionPipeline.from_pretrained`] method.
+Diffusers provides a [safety checker](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/stable_diffusion/safety_checker.py) for older Stable Diffusion models to prevent generating harmful content. It screens the generated output against a set of hardcoded harmful concepts.
 
-```python
+If you want to disable the safety checker, pass `safety_checker=None` in [`~DiffusionPipeline.from_pretrained`] as shown below.
+
+```py
 from diffusers import DiffusionPipeline
 
-pipeline = DiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", safety_checker=None, use_safetensors=True)
+pipeline = DiffusionPipeline.from_pretrained(
+  "stable-diffusion-v1-5/stable-diffusion-v1-5", safety_checker=None
+)
 """
 You have disabled the safety checker for <class 'diffusers.pipelines.stable_diffusion.pipeline_stable_diffusion.StableDiffusionPipeline'> by passing `safety_checker=None`.

-## Checkpoint variants
-
-A checkpoint variant is usually a checkpoint whose weights are:
-
-- Stored in a different floating point type, such as [torch.float16](https://pytorch.org/docs/stable/tensors.html#data-types), because it only requires half the bandwidth and storage to download. You can't use this variant if you're continuing training or using a CPU.
-- Non-exponential mean averaged (EMA) weights which shouldn't be used for inference. You should use this variant to continue finetuning a model.
-
-> [!TIP]
-> When the checkpoints have identical model structures, but they were trained on different datasets and with a different training setup, they should be stored in separate repositories. For example, [stabilityai/stable-diffusion-2](https://hf.co/stabilityai/stable-diffusion-2) and [stabilityai/stable-diffusion-2-1](https://hf.co/stabilityai/stable-diffusion-2-1) are stored in separate repositories.
-
-Otherwise, a variant is **identical** to the original checkpoint. They have exactly the same serialization format (like [safetensors](./using_safetensors)), model structure, and their weights have identical tensor shapes.
-
-| **checkpoint type** | **weight name**                             | **argument for loading weights** |
-|---------------------|---------------------------------------------|----------------------------------|
-| original            | diffusion_pytorch_model.safetensors         |                                  |
-| floating point      | diffusion_pytorch_model.fp16.safetensors    | `variant`, `torch_dtype`         |
-| non-EMA             | diffusion_pytorch_model.non_ema.safetensors | `variant`                        |
-
-There are two important arguments for loading variants:
-
-- `torch_dtype` specifies the floating point precision of the loaded checkpoint. For example, if you want to save bandwidth by loading a fp16 variant, you should set `variant="fp16"` and `torch_dtype=torch.float16` to *convert the weights* to fp16. Otherwise, the fp16 weights are converted to the default fp32 precision.
-
-  If you only set `torch_dtype=torch.float16`, the default fp32 weights are downloaded first and then converted to fp16.
-
-- `variant` specifies which files should be loaded from the repository. For example, if you want to load a non-EMA variant of a UNet from [stable-diffusion-v1-5/stable-diffusion-v1-5](https://hf.co/stable-diffusion-v1-5/stable-diffusion-v1-5/tree/main/unet), set `variant="non_ema"` to download the `non_ema` file.

-
-Use the `variant` parameter in the [`DiffusionPipeline.save_pretrained`] method to save a checkpoint as a different floating point type or as a non-EMA variant. You should try save a variant to the same folder as the original checkpoint, so you have the option of loading both from the same folder.

-
-## DiffusionPipeline explained
-
-As a class method, [`DiffusionPipeline.from_pretrained`] is responsible for two things:
-
-- Download the latest version of the folder structure required for inference and cache it. If the latest folder structure is available in the local cache, [`DiffusionPipeline.from_pretrained`] reuses the cache and won't redownload the files.
-- Load the cached weights into the correct pipeline [class](../api/pipelines/overview#diffusers-summary) - retrieved from the `model_index.json` file - and return an instance of it.
-
-The pipelines' underlying folder structure corresponds directly with their class instances. For example, the [`StableDiffusionPipeline`] corresponds to the folder structure in [`stable-diffusion-v1-5/stable-diffusion-v1-5`](https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5).
-
-```python
-from diffusers import DiffusionPipeline
-
-repo_id = "stable-diffusion-v1-5/stable-diffusion-v1-5"
-pipeline = DiffusionPipeline.from_pretrained(repo_id, use_safetensors=True)
-print(pipeline)

-# Reproducible pipelines
+# Reproducibility
 
-Diffusion models are inherently random which is what allows it to generate different outputs every time it is run. But there are certain times when you want to generate the same output every time, like when you're testing, replicating results, and even [improving image quality](#deterministic-batch-generation). While you can't expect to get identical results across platforms, you can expect reproducible results across releases and platforms within a certain tolerance range (though even this may vary).
+Diffusion is a random process that generates a different output every time. For certain situations like testing and replicating results, you want to generate the same result each time, across releases and platforms within a certain tolerance range.
 
-This guide will show you how to control randomness for deterministic generation on a CPU and GPU.
+This guide will show you how to control sources of randomness and enable deterministic algorithms.
+
+## Generator
+
+Pipelines rely on [torch.randn](https://pytorch.org/docs/stable/generated/torch.randn.html), which uses a different random seed each time, to create the initial noisy tensors. To generate the same output on a CPU or GPU, use a [Generator](https://docs.pytorch.org/docs/stable/generated/torch.Generator.html) to manage how random values are generated.
 
 > [!TIP]
-> We strongly recommend reading PyTorch's [statement about reproducibility](https://pytorch.org/docs/stable/notes/randomness.html):
->
-> "Completely reproducible results are not guaranteed across PyTorch releases, individual commits, or different platforms. Furthermore, results may not be reproducible between CPU and GPU executions, even when using identical seeds."
+> If reproducibility is important to your use case, we recommend always using a CPU `Generator`. The performance loss is often negligible and you'll generate more similar values.
 
-## Control randomness
+<hfoptions id="generator">
+<hfoption id="GPU">
 
-During inference, pipelines rely heavily on random sampling operations which include creating the
-Gaussian noise tensors to denoise and adding noise to the scheduling step.
+The GPU uses a different random number generator than the CPU. Diffusers solves this issue with the [`~utils.torch_utils.randn_tensor`] function to create the random tensor on a CPU and then moving it to the GPU. This function is used everywhere inside the pipeline and you don't need to explicitly call it.
 
-Take a look at the tensor values in the [`DDIMPipeline`] after two inference steps.
+Use [manual_seed](https://docs.pytorch.org/docs/stable/generated/torch.manual_seed.html) as shown below to set a seed.
 
-```python
-from diffusers import DDIMPipeline
-import numpy as np
-
-ddim = DDIMPipeline.from_pretrained( "google/ddpm-cifar10-32", use_safetensors=True)
-image = ddim(num_inference_steps=2, output_type="np").images
-print(np.abs(image).sum())
-```
-
-Running the code above prints one value, but if you run it again you get a different value.
-
-Each time the pipeline is run, [torch.randn](https://pytorch.org/docs/stable/generated/torch.randn.html) uses a different random seed to create the Gaussian noise tensors. This leads to a different result each time it is run and enables the diffusion pipeline to generate a different random image each time.
-
-But if you need to reliably generate the same image, that depends on whether you're running the pipeline on a CPU or GPU.
-
-> [!TIP]
-> It might seem unintuitive to pass `Generator` objects to a pipeline instead of the integer value representing the seed. However, this is the recommended design when working with probabilistic models in PyTorch because a `Generator` is a *random state* that can be passed to multiple pipelines in a sequence. As soon as the `Generator` is consumed, the *state* is changed in place which means even if you passed the same `Generator` to a different pipeline, it won't produce the same result because the state is already changed.
-
-<hfoptions id="hardware">
-<hfoption id="CPU">
-
-To generate reproducible results on a CPU, you'll need to use a PyTorch [Generator](https://pytorch.org/docs/stable/generated/torch.Generator.html) and set a seed. Now when you run the code, it always prints a value of `1491.1711` because the `Generator` object with the seed is passed to all the random functions in the pipeline. You should get a similar, if not the same, result on whatever hardware and PyTorch version you're using.
-
-```python
+```py
 import torch
 import numpy as np
 from diffusers import DDIMPipeline
 
-ddim = DDIMPipeline.from_pretrained("google/ddpm-cifar10-32", use_safetensors=True)
+ddim = DDIMPipeline.from_pretrained("google/ddpm-cifar10-32", device_map="cuda")
+generator = torch.manual_seed(0)
+image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
+print(np.abs(image).sum())
+```
+
+</hfoption>
+<hfoption id="CPU">
+
+Set `device="cpu"` in the `Generator` and use [manual_seed](https://docs.pytorch.org/docs/stable/generated/torch.manual_seed.html) to set a seed for generating random numbers.
+
+```py
+import torch
+import numpy as np
+from diffusers import DDIMPipeline
+
+ddim = DDIMPipeline.from_pretrained("google/ddpm-cifar10-32")
 generator = torch.Generator(device="cpu").manual_seed(0)
 image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
 print(np.abs(image).sum())
 ```
 
-</hfoption>
-<hfoption id="GPU">
-
-Writing a reproducible pipeline on a GPU is a bit trickier, and full reproducibility across different hardware is not guaranteed because matrix multiplication - which diffusion pipelines require a lot of - is less deterministic on a GPU than a CPU. For example, if you run the same code example from the CPU example, you'll get a different result even though the seed is identical. This is because the GPU uses a different random number generator than the CPU.
-
-```python
-import torch
-import numpy as np
-from diffusers import DDIMPipeline
-
-ddim = DDIMPipeline.from_pretrained("google/ddpm-cifar10-32", use_safetensors=True)
-ddim.to("cuda")
-generator = torch.Generator(device="cuda").manual_seed(0)
-image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
-print(np.abs(image).sum())
-```
-
-To avoid this issue, Diffusers has a [`~utils.torch_utils.randn_tensor`] function for creating random noise on the CPU, and then moving the tensor to a GPU if necessary. The [`~utils.torch_utils.randn_tensor`] function is used everywhere inside the pipeline. Now you can call [torch.manual_seed](https://pytorch.org/docs/stable/generated/torch.manual_seed.html) which automatically creates a CPU `Generator` that can be passed to the pipeline even if it is being run on a GPU.
-
-```python
-import torch
-import numpy as np
-from diffusers import DDIMPipeline
-
-ddim = DDIMPipeline.from_pretrained("google/ddpm-cifar10-32", use_safetensors=True)
-ddim.to("cuda")
-generator = torch.manual_seed(0)
-image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
-print(np.abs(image).sum())
-```
-
-> [!TIP]
-> If reproducibility is important to your use case, we recommend always passing a CPU `Generator`. The performance loss is often negligible and you'll generate more similar values than if the pipeline had been run on a GPU.
-
-Finally, more complex pipelines such as [`UnCLIPPipeline`], are often extremely
-susceptible to precision error propagation. You'll need to use
-exactly the same hardware and PyTorch version for full reproducibility.
-
 </hfoption>
 </hfoptions>
 
+The `Generator` object should be passed to the pipeline instead of an integer seed. `Generator` maintains a *random state* that is consumed and modified when used. Once consumed, the same `Generator` object produces different results in subsequent calls, even across different pipelines, because it's *state* has changed.
+
+```py
+generator = torch.manual_seed(0)
+
+for _ in range(5):
+-    image = pipeline(prompt, generator=generator)
++    image = pipeline(prompt, generator=torch.manual_seed(0))
+```

 ## Deterministic algorithms
 
-You can also configure PyTorch to use deterministic algorithms to create a reproducible pipeline. The downside is that deterministic algorithms may be slower than non-deterministic ones and you may observe a decrease in performance.
+PyTorch supports [deterministic algorithms](https://docs.pytorch.org/docs/stable/notes/randomness.html#avoiding-nondeterministic-algorithms) - where available - for certain operations so they produce the same results. Deterministic algorithms may be slower and decrease performance.
 
-Non-deterministic behavior occurs when operations are launched in more than one CUDA stream. To avoid this, set the environment variable [CUBLAS_WORKSPACE_CONFIG](https://docs.nvidia.com/cuda/cublas/index.html#results-reproducibility) to `:16:8` to only use one buffer size during runtime.
-
-PyTorch typically benchmarks multiple algorithms to select the fastest one, but if you want reproducibility, you should disable this feature because the benchmark may select different algorithms each time. Set Diffusers [enable_full_determinism](https://github.com/huggingface/diffusers/blob/142f353e1c638ff1d20bd798402b68f72c1ebbdd/src/diffusers/utils/testing_utils.py#L861) to enable deterministic algorithms.
-
-```py
-enable_full_determinism()
-```
-
-Now when you run the same pipeline twice, you'll get identical results.
+Use Diffusers' [enable_full_determinism](https://github.com/huggingface/diffusers/blob/142f353e1c638ff1d20bd798402b68f72c1ebbdd/src/diffusers/utils/testing_utils.py#L861) function to enable deterministic algorithms.
 
 ```py
 import torch
-from diffusers import DDIMScheduler, StableDiffusionPipeline
+from diffusers_utils import enable_full_determinism
 
-pipe = StableDiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", use_safetensors=True).to("cuda")
-pipe.scheduler = DDIMScheduler.from_config(pipe.scheduler.config)
-g = torch.Generator(device="cuda")
-
-prompt = "A bear is playing a guitar on Times Square"
-
-g.manual_seed(0)
-result1 = pipe(prompt=prompt, num_inference_steps=50, generator=g, output_type="latent").images
-
-g.manual_seed(0)
-result2 = pipe(prompt=prompt, num_inference_steps=50, generator=g, output_type="latent").images
-
-print("L_inf dist =", abs(result1 - result2).max())
-"L_inf dist = tensor(0., device='cuda:0')"
+enable_full_determinism()
 ```
+
+Under the hood, `enable_full_determinism` works by:
+
+- Setting the environment variable [CUBLAS_WORKSPACE_CONFIG](https://docs.nvidia.com/cuda/cublas/index.html#results-reproducibility) to `:16:8` to only use one buffer size during rntime. Non-deterministic behavior occurs when operations are used in more than one CUDA stream.
+- Disabling benchmarking to find the fastest convolution operation by setting `torch.backends.cudnn.benchmark=False`. Non-deterministic behavior occurs because the benchmark may select different algorithms each time depending on hardware or benchmarking noise.
+- Disabling TensorFloat32 (TF32) operations in favor of more precise and consistent full-precision operations.
+
+
+## Resources
+
+We strongly recommend reading PyTorch's developer notes about [Reproducibility](https://docs.pytorch.org/docs/stable/notes/randomness.html). You can try to limit randomness, but it is not *guaranteed* even with an identical seed.

 Most images look very similar and are comparable in quality. Again, it often comes down to your specific use case so a good approach is to run multiple different schedulers and compare the results.
 
-### Flax schedulers
-
-To compare Flax schedulers, you need to additionally load the scheduler state into the model parameters. For example, let's change the default scheduler in [`FlaxStableDiffusionPipeline`] to use the super fast [`FlaxDPMSolverMultistepScheduler`].
-
-> [!WARNING]
-> The [`FlaxLMSDiscreteScheduler`] and [`FlaxDDPMScheduler`] are not compatible with the [`FlaxStableDiffusionPipeline`] yet.
-
-```py
-import jax
-import numpy as np
-from flax.jax_utils import replicate
-from flax.training.common_utils import shard
-from diffusers import FlaxStableDiffusionPipeline, FlaxDPMSolverMultistepScheduler
-
-scheduler, scheduler_state = FlaxDPMSolverMultistepScheduler.from_pretrained(
-    "stable-diffusion-v1-5/stable-diffusion-v1-5",
-    subfolder="scheduler"
-)
-pipeline, params = FlaxStableDiffusionPipeline.from_pretrained(

-    scheduler=scheduler,
-    variant="bf16",
-    dtype=jax.numpy.bfloat16,
-)
-params["scheduler"] = scheduler_state
-```
-
-Then you can take advantage of Flax's compatibility with TPUs to generate a number of images in parallel. You'll need to make a copy of the model parameters for each available device and then split the inputs across them to generate your desired number of images.
-
-```py
-# Generate 1 image per parallel device (8 on TPUv2-8 or TPUv3-8)
-prompt = "A photograph of an astronaut riding a horse on Mars, high resolution, high definition."
-num_samples = jax.device_count()
-prompt_ids = pipeline.prepare_inputs([prompt] * num_samples)
-
-prng_seed = jax.random.PRNGKey(0)
-num_inference_steps = 25
-
-# shard inputs and rng
-params = replicate(params)
-prng_seed = jax.random.split(prng_seed, jax.device_count())
-prompt_ids = shard(prompt_ids)

-images = pipeline.numpy_to_pil(np.asarray(images.reshape((num_samples,) + images.shape[-3:])))

-
 ## Models
 
 Models are loaded from the [`ModelMixin.from_pretrained`] method, which downloads and caches the latest version of the model weights and configurations. If the latest files are available in the local cache, [`~ModelMixin.from_pretrained`] reuses files in the cache instead of re-downloading them.

-# JAX/Flax
-
-[[open-in-colab]]
-
-🤗 Diffusers supports Flax for super fast inference on Google TPUs, such as those available in Colab, Kaggle or Google Cloud Platform. This guide shows you how to run inference with Stable Diffusion using JAX/Flax.
-
-Before you begin, make sure you have the necessary libraries installed:
-
-```py
-# uncomment to install the necessary libraries in Colab
-#!pip install -q jax==0.3.25 jaxlib==0.3.25 flax transformers ftfy
-#!pip install -q diffusers
-```
-
-You should also make sure you're using a TPU backend. While JAX does not run exclusively on TPUs, you'll get the best performance on a TPU because each server has 8 TPU accelerators working in parallel.
-
-If you are running this guide in Colab, select *Runtime* in the menu above, select the option *Change runtime type*, and then select *TPU* under the *Hardware accelerator* setting. Import JAX and quickly check whether you're using a TPU:
-
-```python
-import jax
-import jax.tools.colab_tpu
-jax.tools.colab_tpu.setup_tpu()
-
-num_devices = jax.device_count()
-device_type = jax.devices()[0].device_kind
-
-print(f"Found {num_devices} JAX devices of type {device_type}.")
-assert (
-    "TPU" in device_type,
-    "Available device is not a TPU, please select TPU from Runtime > Change runtime type > Hardware accelerator"
-)
-# Found 8 JAX devices of type Cloud TPU.
-```
-
-Great, now you can import the rest of the dependencies you'll need:
-
-```python
-import jax.numpy as jnp
-from jax import pmap
-from flax.jax_utils import replicate
-from flax.training.common_utils import shard
-
-from diffusers import FlaxStableDiffusionPipeline
-```
-
-## Load a model
-
-Flax is a functional framework, so models are stateless and parameters are stored outside of them. Loading a pretrained Flax pipeline returns *both* the pipeline and the model weights (or parameters). In this guide, you'll use `bfloat16`, a more efficient half-float type that is supported by TPUs (you can also use `float32` for full precision if you want).
-
-```python
-dtype = jnp.bfloat16
-pipeline, params = FlaxStableDiffusionPipeline.from_pretrained(
-    "CompVis/stable-diffusion-v1-4",
-    variant="bf16",
-    dtype=dtype,
-)
-```
-
-## Inference
-
-TPUs usually have 8 devices working in parallel, so let's use the same prompt for each device. This means you can perform inference on 8 devices at once, with each device generating one image. As a result, you'll get 8 images in the same amount of time it takes for one chip to generate a single image!
-
-<Tip>
-
-Learn more details in the [How does parallelization work?](#how-does-parallelization-work) section.
-
-</Tip>
-
-After replicating the prompt, get the tokenized text ids by calling the `prepare_inputs` function on the pipeline. The length of the tokenized text is set to 77 tokens as required by the configuration of the underlying CLIP text model.
-
-```python
-prompt = "A cinematic film still of Morgan Freeman starring as Jimi Hendrix, portrait, 40mm lens, shallow depth of field, close up, split lighting, cinematic"
-prompt = [prompt] * jax.device_count()
-prompt_ids = pipeline.prepare_inputs(prompt)
-prompt_ids.shape
-# (8, 77)
-```
-
-Model parameters and inputs have to be replicated across the 8 parallel devices. The parameters dictionary is replicated with [`flax.jax_utils.replicate`](https://flax.readthedocs.io/en/latest/api_reference/flax.jax_utils.html#flax.jax_utils.replicate) which traverses the dictionary and changes the shape of the weights so they are repeated 8 times. Arrays are replicated using `shard`.
-
-```python
-# parameters
-p_params = replicate(params)
-
-# arrays
-prompt_ids = shard(prompt_ids)
-prompt_ids.shape
-# (8, 1, 77)
-```
-
-This shape means each one of the 8 devices receives as an input a `jnp` array with shape `(1, 77)`, where `1` is the batch size per device. On TPUs with sufficient memory, you could have a batch size larger than `1` if you want to generate multiple images (per chip) at once.
-
-Next, create a random number generator to pass to the generation function. This is standard procedure in Flax, which is very serious and opinionated about random numbers. All functions that deal with random numbers are expected to receive a generator to ensure reproducibility, even when you're training across multiple distributed devices.
-
-The helper function below uses a seed to initialize a random number generator. As long as you use the same seed, you'll get the exact same results. Feel free to use different seeds when exploring results later in the guide.
-
-```python
-def create_key(seed=0):
-    return jax.random.PRNGKey(seed)
-```
-
-The helper function, or `rng`, is split 8 times so each device receives a different generator and generates a different image.
-
-```python
-rng = create_key(0)
-rng = jax.random.split(rng, jax.device_count())
-```
-
-To take advantage of JAX's optimized speed on a TPU, pass `jit=True` to the pipeline to compile the JAX code into an efficient representation and to ensure the model runs in parallel across the 8 devices.
-
-<Tip warning={true}>
-
-You need to ensure all your inputs have the same shape in subsequent calls, otherwise JAX will need to recompile the code which is slower.
-
-</Tip>
-
-The first inference run takes more time because it needs to compile the code, but subsequent calls (even with different inputs) are much faster. For example, it took more than a minute to compile on a TPU v2-8, but then it takes about **7s** on a future inference run!
-
-```py
-%%time
-images = pipeline(prompt_ids, p_params, rng, jit=True)[0]
-
-# CPU times: user 56.2 s, sys: 42.5 s, total: 1min 38s
-# Wall time: 1min 29s
-```
-
-The returned array has shape `(8, 1, 512, 512, 3)` which should be reshaped to remove the second dimension and get 8 images of `512 × 512 × 3`. Then you can use the [`~utils.numpy_to_pil`] function to convert the arrays into images.
-
-```python
-from diffusers.utils import make_image_grid
-
-images = images.reshape((images.shape[0] * images.shape[1],) + images.shape[-3:])
-images = pipeline.numpy_to_pil(images)
-make_image_grid(images, rows=2, cols=4)
-```

-
-## Using different prompts
-
-You don't necessarily have to use the same prompt on all devices. For example, to generate 8 different prompts:
-
-```python
-prompts = [
-    "Labrador in the style of Hokusai",
-    "Painting of a squirrel skating in New York",
-    "HAL-9000 in the style of Van Gogh",
-    "Times Square under water, with fish and a dolphin swimming around",
-    "Ancient Roman fresco showing a man working on his laptop",
-    "Close-up photograph of young black woman against urban background, high quality, bokeh",
-    "Armchair in the shape of an avocado",
-    "Clown astronaut in space, with Earth in the background",
-]
-
-prompt_ids = pipeline.prepare_inputs(prompts)
-prompt_ids = shard(prompt_ids)
-
-images = pipeline(prompt_ids, p_params, rng, jit=True).images
-images = images.reshape((images.shape[0] * images.shape[1],) + images.shape[-3:])
-images = pipeline.numpy_to_pil(images)
-
-make_image_grid(images, 2, 4)
-```

-## How does parallelization work?
-
-The Flax pipeline in 🤗 Diffusers automatically compiles the model and runs it in parallel on all available devices. Let's take a closer look at how that process works.
-
-JAX parallelization can be done in multiple ways. The easiest one revolves around using the [`jax.pmap`](https://jax.readthedocs.io/en/latest/_autosummary/jax.pmap.html) function to achieve single-program multiple-data (SPMD) parallelization. It means running several copies of the same code, each on different data inputs. More sophisticated approaches are possible, and you can go over to the JAX [documentation](https://jax.readthedocs.io/en/latest/index.html) to explore this topic in more detail if you are interested!
-
-`jax.pmap` does two things:
-
-1. Compiles (or "`jit`s") the code which is similar to `jax.jit()`. This does not happen when you call `pmap`, and only the first time the `pmap`ped function is called.
-2. Ensures the compiled code runs in parallel on all available devices.
-
-To demonstrate, call `pmap` on the pipeline's `_generate` method (this is a private method that generates images and may be renamed or removed in future releases of 🤗 Diffusers):
-
-```python
-p_generate = pmap(pipeline._generate)
-```
-
-After calling `pmap`, the prepared function `p_generate` will:
-
-1. Make a copy of the underlying function, `pipeline._generate`, on each device.
-2. Send each device a different portion of the input arguments (this is why it's necessary to call the *shard* function). In this case, `prompt_ids` has shape `(8, 1, 77, 768)` so the array is split into 8 and each copy of `_generate` receives an input with shape `(1, 77, 768)`.
-
-The most important thing to pay attention to here is the batch size (1 in this example), and the input dimensions that make sense for your code. You don't have to change anything else to make the code work in parallel.
-
-The first time you call the pipeline takes more time, but the calls afterward are much faster. The `block_until_ready` function is used to correctly measure inference time because JAX uses asynchronous dispatch and returns control to the Python loop as soon as it can. You don't need to use that in your code; blocking occurs automatically when you want to use the result of a computation that has not yet been materialized.
-
-```py
-%%time
-images = p_generate(prompt_ids, p_params, rng)
-images = images.block_until_ready()
-
-# CPU times: user 1min 15s, sys: 18.2 s, total: 1min 34s
-# Wall time: 1min 15s
-```
-
-Check your image dimensions to see if they're correct:
-
-```python
-images.shape
-# (8, 1, 512, 512, 3)
-```

+
+对于4-9类贡献，您需要提交PR（拉取请求），具体操作详见[如何提交PR](#how-to-open-a-pr)章节。
+
+### 1. 在Diffusers讨论区或Discord提问与解答
+
+任何与Diffusers库相关的问题或讨论都可以发布在[官方论坛](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/)或[Discord频道](https://discord.gg/G7tWnz98XR)，包括但不限于：
+- 分享训练/推理实验报告
+- 展示个人项目
+- 咨询非官方训练示例
+- 项目提案
+- 通用反馈
+- 论文解读
+- 基于Diffusers库的个人项目求助
+- 一般性问题
+- 关于diffusion模型的伦理讨论
+- ...
+
+论坛/Discord上的每个问题都能促使社区公开分享知识，很可能帮助未来遇到相同问题的初学者。请务必提出您的疑问。
+同样地，通过回答问题您也在为社区创造公共知识文档，这种贡献极具价值。
+
+**请注意**：提问/回答时投入的精力越多，产生的公共知识质量就越高。精心构建的问题与专业解答能形成高质量知识库，而表述不清的问题则可能降低讨论价值。
+
+低质量的问题或回答会降低公共知识库的整体质量。  
+简而言之，高质量的问题或回答应具备*精确性*、*简洁性*、*相关性*、*易于理解*、*可访问性*和*格式规范/表述清晰*等特质。更多详情请参阅[如何提交优质议题](#how-to-write-a-good-issue)章节。
+
+**关于渠道的说明**：  
+[*论坛*](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/63)的内容能被谷歌等搜索引擎更好地收录，且帖子按热度而非时间排序，便于查找历史问答。此外，论坛内容更容易被直接链接引用。  
+而*Discord*采用即时聊天模式，适合快速交流。虽然在Discord上可能更快获得解答，但信息会随时间淹没，且难以回溯历史讨论。因此我们强烈建议在论坛发布优质问答，以构建可持续的社区知识库。若Discord讨论产生有价值结论，建议将成果整理发布至论坛以惠及更多读者。
+
+### 2. 在GitHub议题页提交新议题
+
+🧨 Diffusers库的稳健性离不开用户的问题反馈，感谢您的报错。
+
+请注意：GitHub议题仅限处理与Diffusers库代码直接相关的技术问题、错误报告、功能请求或库设计反馈。  
+简言之，**与Diffusers库代码（含文档）无关**的内容应发布至[论坛](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/63)或[Discord](https://discord.gg/G7tWnz98XR)。
+
+**提交新议题时请遵循以下准则**：
+- 确认是否已有类似议题（使用GitHub议题页的搜索栏）
+- 请勿在现有议题下追加新问题。若存在高度关联议题，应新建议题并添加相关链接
+- 确保使用英文提交。非英语用户可通过[DeepL](https://www.deepl.com/translator)等免费工具翻译
+- 检查升级至最新Diffusers版本是否能解决问题。提交前请确认`python -c "import diffusers; print(diffusers.__version__)"`显示的版本号不低于最新版本
+- 记请记住，你在提交新issue时投入的精力越多，得到的回答质量就越高，Diffusers项目的整体issue质量也会越好。
+
+新issue通常包含以下内容：
+
+#### 2.1 可复现的最小化错误报告
+
+错误报告应始终包含可复现的代码片段，并尽可能简洁明了。具体而言：
+- 尽量缩小问题范围，**不要直接粘贴整个代码文件**
+- 规范代码格式
+- 除Diffusers依赖库外，不要包含其他外部库

+
+### 6. 贡献社区流程
+
+> [!TIP]
+> 阅读[社区流程](../using-diffusers/custom_pipeline_overview#community-pipelines)指南了解GitHub与Hugging Face Hub社区流程的区别。若想了解我们设立社区流程的原因，请查看GitHub Issue [#841](https://github.com/huggingface/diffusers/issues/841)（简而言之，我们无法维护diffusion模型所有可能的推理使用方式，但也不希望限制社区构建这些流程）。
+
+贡献社区流程是向社区分享创意与成果的绝佳方式。您可以在[`DiffusionPipeline`]基础上构建流程，任何人都能通过设置`custom_pipeline`参数加载使用。本节将指导您创建一个简单的"单步"流程——UNet仅执行单次前向传播并调用调度器一次。
+
+1. 为社区流程创建one_step_unet.py文件。只要用户已安装相关包，该文件可包含任意所需包。确保仅有一个继承自[`DiffusionPipeline`]的流程类，用于从Hub加载模型权重和调度器配置。在`__init__`函数中添加UNet和调度器。
+
+    同时添加`register_modules`函数，确保您的流程及其组件可通过[`~DiffusionPipeline.save_pretrained`]保存。
+
+```py
+from diffusers import DiffusionPipeline
+import torch
+
+class UnetSchedulerOneForwardPipeline(DiffusionPipeline):
+    def __init__(self, unet, scheduler):
+        super().__init__()
+
+        self.register_modules(unet=unet, scheduler=scheduler)
+```
+
+2. 在前向传播中（建议定义为`__call__`），可添加任意功能。对于"单步"流程，创建随机图像并通过设置`timestep=1`调用UNet和调度器一次。
+
+```py
+  from diffusers import DiffusionPipeline
+  import torch
+
+  class UnetSchedulerOneForwardPipeline(DiffusionPipeline):
+      def __init__(self, unet, scheduler):
+          super().__init__()
+
+          self.register_modules(unet=unet, scheduler=scheduler)
+
+      def __call__(self):
+          image = torch.randn(
+              (1, self.unet.config.in_channels, self.unet.config.sample_size, self.unet.config.sample_size),
+          )
+          timestep = 1
+
+          model_output = self.unet(image, timestep).sample
+          scheduler_output = self.scheduler.step(model_output, timestep, image).prev_sample
+
+          return scheduler_output
+```
+
+现在您可以通过传入UNet和调度器来运行流程，若流程结构相同也可加载预训练权重。
+
+```python
+from diffusers import DDPMScheduler, UNet2DModel
+
+scheduler = DDPMScheduler()
+unet = UNet2DModel()
+
+pipeline = UnetSchedulerOneForwardPipeline(unet=unet, scheduler=scheduler)
+output = pipeline()
+# 加载预训练权重
+pipeline = UnetSchedulerOneForwardPipeline.from_pretrained("google/ddpm-cifar10-32", use_safetensors=True)
+output = pipeline()
+```
+
+您可以选择将pipeline作为GitHub社区pipeline或Hub社区pipeline进行分享。
+
+<hfoptions id="pipeline类型">
+<hfoption id="GitHub pipeline">
+
+通过向Diffusers[代码库](https://github.com/huggingface/diffusers)提交拉取请求来分享GitHub pipeline，将one_step_unet.py文件添加到[examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community)子文件夹中。
+
+</hfoption>
+<hfoption id="Hub pipeline">
+
+通过在Hub上创建模型仓库并上传one_step_unet.py文件来分享Hub pipeline。
+
+</hfoption>
+</hfoptions>
+
+### 7. 贡献训练示例
+
+Diffusers训练示例是位于[examples](https://github.com/huggingface/diffusers/tree/main/examples)目录下的训练脚本集合。
+
+我们支持两种类型的训练示例：
+
+- 官方训练示例
+- 研究型训练示例
+
+研究型训练示例位于[examples/research_projects](https://github.com/huggingface/diffusers/tree/main/examples/research_projects)，而官方训练示例包含[examples](https://github.com/huggingface/diffusers/tree/main/examples)目录下除`research_projects`和`community`外的所有文件夹。
+官方训练示例由Diffusers核心维护者维护，研究型训练示例则由社区维护。
+这与[6. 贡献社区pipeline](#6-contribute-a-community-pipeline)中关于官方pipeline与社区pipeline的原因相同：核心维护者不可能维护diffusion模型的所有可能训练方法。
+如果Diffusers核心维护者和社区认为某种训练范式过于实验性或不够普及，相应训练代码应放入`research_projects`文件夹并由作者维护。
+
+官方训练和研究型示例都包含一个目录，其中含有一个或多个训练脚本、`requirements.txt`文件和`README.md`文件。用户使用时需要先克隆代码库：
+
+```bash
+git clone https://github.com/huggingface/diffusers
+```
+
+并安装训练所需的所有额外依赖：
+
+```bash
+cd diffusers
+pip install -r examples/<your-example-folder>/requirements.txt
+```
+
+因此添加示例时，`requirements.txt`文件应定义训练示例所需的所有pip依赖项，安装完成后用户即可运行示例训练脚本。可参考[DreamBooth的requirements.txt文件](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/requirements.txt)。
+- 运行示例所需的所有代码应集中在单个Python文件中  
+- 用户应能通过命令行`python <your-example>.py --args`直接运行示例  
+- **示例**应保持简洁，主要展示如何使用Diffusers进行训练。示例脚本的目的**不是**创建最先进的diffusion模型，而是复现已知训练方案，避免添加过多自定义逻辑。因此，这些示例也力求成为优质的教学材料。
+
+提交示例时，强烈建议参考现有示例（如[dreambooth](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/train_dreambooth.py)）来了解规范格式。  
+我们强烈建议贡献者使用[Accelerate库](https://github.com/huggingface/accelerate)，因其与Diffusers深度集成。  
+当示例脚本完成后，请确保添加详细的`README.md`说明使用方法，包括：  
+- 运行示例的具体命令（示例参见[此处](https://github.com/huggingface/diffusers/tree/main/examples/dreambooth#running-locally-with-pytorch)）  
+- 训练结果链接（日志/模型等），展示用户可预期的效果（示例参见[此处](https://api.wandb.ai/report/patrickvonplaten/xm6cd5q5)）  
+- 若添加非官方/研究性训练示例，**必须注明**维护者信息（含Git账号），格式参照[此处](https://github.com/huggingface/diffusers/tree/main/examples/research_projects/intel_opts#diffusers-examples-with-intel-optimizations)  
+
+贡献官方训练示例时，还需在对应目录添加测试文件（如[examples/dreambooth/test_dreambooth.py](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/test_dreambooth.py)），非官方示例无需此步骤。
+
+### 8. 处理"Good second issue"类问题
+
+标有[Good second issue](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22Good+second+issue%22)标签的问题通常比[Good first issues](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)更复杂。  
+这类问题的描述通常不会提供详细解决指引，需要贡献者对库有较深理解。  
+若您想解决此类问题，可直接提交PR并关联对应issue。若已有未合并的PR，请分析原因后提交改进版。需注意，Good second issue类PR的合并难度通常高于good first issues。在需要帮助的时候请不要犹豫，大胆的向核心维护者询问。
+
+### 9. 添加管道、模型和调度器
+
+管道（pipelines）、模型（models）和调度器（schedulers）是Diffusers库中最重要的组成部分。它们提供了对最先进diffusion技术的便捷访问，使得社区能够构建强大的生成式AI应用。
+
+通过添加新的模型、管道或调度器，您可能为依赖Diffusers的任何用户界面开启全新的强大用例，这对整个生成式AI生态系统具有巨大价值。
+
+Diffusers针对这三类组件都有一些开放的功能请求——如果您还不确定要添加哪个具体组件，可以浏览以下链接：
+- [模型或管道](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+pipeline%2Fmodel%22)
+- [调度器](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+scheduler%22)
+
+在添加任何组件之前，强烈建议您阅读[设计哲学指南](philosophy)，以更好地理解这三类组件的设计理念。请注意，如果添加的模型、调度器或管道与我们的设计理念存在严重分歧，我们将无法合并，因为这会导致API不一致。如果您从根本上不同意某个设计选择，请改为提交[反馈问题](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feedback.md&title=)，以便讨论是否应该更改库中的特定设计模式/选择，以及是否更新我们的设计哲学。保持库内的一致性对我们非常重要。
+
+请确保在PR中添加原始代码库/论文的链接，并最好直接在PR中@原始作者，以便他们可以跟踪进展并在有疑问时提供帮助。
+
+如果您在PR过程中遇到不确定或卡住的情况，请随时留言请求初步审查或帮助。
+
+#### 复制机制（Copied from）
+
+在添加任何管道、模型或调度器代码时，理解`# Copied from`机制是独特且重要的。您会在整个Diffusers代码库中看到这种机制，我们使用它的原因是为了保持代码库易于理解和维护。用`# Copied from`机制标记代码会强制标记的代码与复制来源的代码完全相同。这使得每当您运行`make fix-copies`时，可以轻松更新并将更改传播到多个文件。
+
+例如，在下面的代码示例中，[`~diffusers.pipelines.stable_diffusion.StableDiffusionPipelineOutput`]是原始代码，而`AltDiffusionPipelineOutput`使用`# Copied from`机制来复制它。唯一的区别是将类前缀从`Stable`改为`Alt`。
+
+```py
+# 从 diffusers.pipelines.stable_diffusion.pipeline_output.StableDiffusionPipelineOutput 复制并将 Stable 替换为 Alt
+class AltDiffusionPipelineOutput(BaseOutput):
+    """
+    Output class for Alt Diffusion pipelines.
+
+    Args:
+        images (`List[PIL.Image.Image]` or `np.ndarray`)
+            List of denoised PIL images of length `batch_size` or NumPy array of shape `(batch_size, height, width,
+            num_channels)`.
+        nsfw_content_detected (`List[bool]`)
+            List indicating whether the corresponding generated image contains "not-safe-for-work" (nsfw) content or
+            `None` if safety checking could not be performed.
+    """
+```

+
+## 如何撰写优质问题
+
+**问题描述越清晰，被快速解决的可能性就越高。**
+
+1. 确保使用了正确的issue模板。您可以选择*错误报告*、*功能请求*、*API设计反馈*、*新模型/流水线/调度器添加*、*论坛*或空白issue。在[新建issue](https://github.com/huggingface/diffusers/issues/new/choose)时务必选择正确的模板。
+2. **精确描述**：为issue起一个恰当的标题。尽量用最简练的语言描述问题。提交issue时越精确，理解问题和潜在解决方案所需的时间就越少。确保一个issue只针对一个问题，不要将多个问题放在同一个issue中。如果发现多个问题，请分别创建多个issue。如果是错误报告，请尽可能精确描述错误类型——不应只写"diffusers出错"。
+3. **可复现性**：无法复现的代码片段 == 无法解决问题。如果遇到错误，维护人员必须能够**复现**它。确保包含一个可以复制粘贴到Python解释器中复现问题的代码片段。确保您的代码片段是可运行的，即没有缺少导入或图像链接等问题。issue应包含错误信息和可直接复制粘贴以复现相同错误的代码片段。如果issue涉及本地模型权重或无法被读者访问的本地数据，则问题无法解决。如果无法共享数据或模型，请尝试创建虚拟模型或虚拟数据。
+4. **最小化原则**：通过尽可能简洁的描述帮助读者快速理解问题。删除所有与问题无关的代码/信息。如果发现错误，请创建最简单的代码示例来演示问题，不要一发现错误就把整个工作流程都转储到issue中。例如，如果在训练模型时某个阶段出现错误或训练过程中遇到问题时，应首先尝试理解训练代码的哪部分导致了错误，并用少量代码尝试复现。建议使用模拟数据替代完整数据集进行测试。
+5. 添加引用链接。当提及特定命名、方法或模型时，请务必提供引用链接以便读者理解。若涉及具体PR或issue，请确保添加对应链接。不要假设读者了解你所指内容。issue中引用链接越丰富越好。
+6. 规范格式。请确保规范格式化issue内容：Python代码使用代码语法块，错误信息使用标准代码语法。详见[GitHub官方格式文档](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax)。
+7. 请将issue视为百科全书的精美词条，而非待解决的工单。每个规范撰写的issue不仅是向维护者有效传递问题的方式，更是帮助社区深入理解库特性的公共知识贡献。
+
+## 优质PR编写规范
+
+1. 保持风格统一。理解现有设计模式和语法规范，确保新增代码与代码库现有结构无缝衔接。显著偏离现有设计模式或用户界面的PR将不予合并。
+2. 聚焦单一问题。每个PR应当只解决一个明确问题，避免"顺手修复其他问题"的陷阱。包含多个无关修改的PR会极大增加审查难度。
+3. 如适用，建议添加代码片段演示新增功能的使用方法。
+4. PR标题应准确概括其核心贡献。
+5. 若PR针对某个issue，请在描述中注明issue编号以建立关联（也让关注该issue的用户知晓有人正在处理）；
+6. 进行中的PR请在标题添加`[WIP]`前缀。这既能避免重复劳动，也可与待合并PR明确区分；
+7. 文本表述与格式要求请参照[优质issue编写规范](#how-to-write-a-good-issue)；
+8. 确保现有测试用例全部通过；
+9. 必须添加高覆盖率测试。未经充分测试的代码不予合并。
+- 若新增`@slow`测试，请使用`RUN_SLOW=1 python -m pytest tests/test_my_new_model.py`确保通过。
+CircleCI不执行慢速测试，但GitHub Actions会每日夜间运行！
+10. 所有公开方法必须包含格式规范、兼容markdown的说明文档。可参考[`pipeline_latent_diffusion.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/latent_diffusion/pipeline_latent_diffusion.py) 
+11. 由于代码库快速增长，必须确保不会添加明显增加仓库体积的文件（如图片、视频等非文本文件）。建议优先使用托管在hf.co的`dataset`（例如[`hf-internal-testing`](https://huggingface.co/hf-internal-testing)或[huggingface/documentation-images](https://huggingface.co/datasets/huggingface/documentation-images)）存放这类文件。若为外部贡献，可将图片添加到PR中并请Hugging Face成员将其迁移至该数据集。
+
+## 提交PR流程
+
+编写代码前，强烈建议先搜索现有PR或issue，确认没有重复工作。如有疑问，建议先创建issue获取反馈。
+
+贡献至🧨 Diffusers需要基本的`git`技能。虽然`git`学习曲线较高，但其拥有最完善的手册。在终端输入`git --help`即可查阅，或参考书籍[Pro Git](https://git-scm.com/book/en/v2)。
+
+请按以下步骤操作（[支持的Python版本](https://github.com/huggingface/diffusers/blob/83bc6c94eaeb6f7704a2a428931cf2d9ad973ae9/setup.py#L270)）：
+
+1. 在[仓库页面](https://github.com/huggingface/diffusers)点击"Fork"按钮创建代码副本至您的GitHub账户
+
+2. 克隆fork到本地，并添加主仓库为远程源：
+ ```bash
+ $ git clone git@github.com:<您的GitHub账号>/diffusers.git
+ $ cd diffusers
+ $ git remote add upstream https://github.com/huggingface/diffusers.git
+ ```
+
+3. 创建新分支进行开发：
+ ```bash
+ $ git checkout -b 您的开发分支名称
+ ```
+**禁止**直接在`main`分支上修改
+
+4. 在虚拟环境中运行以下命令配置开发环境：
+ ```bash
+ $ pip install -e ".[dev]"
+ ```
+若已克隆仓库，可能需要先执行`git pull`获取最新代码
+
+5. 在您的分支上开发功能
+
+开发过程中应确保测试通过。可运行受影响测试：
+ ```bash
+ $ pytest tests/<待测文件>.py
+ ```
+执行测试前请安装测试依赖：
+ ```bash
+ $ pip install -e ".[test]"
+ ```
+也可运行完整测试套件（需高性能机器）：
+ ```bash
+ $ make test
+ ```
+
+🧨 Diffusers使用`black`和`isort`工具保持代码风格统一。修改后请执行自动化格式校正与代码验证，以下内容无法通过以下命令一次性自动化完成：
+
+```bash
+$ make style
+```
+
+🧨 Diffusers 还使用 `ruff` 和一些自定义脚本来检查代码错误。虽然质量控制流程会在 CI 中运行，但您也可以通过以下命令手动执行相同的检查：
+
+```bash
+$ make quality
+```
+
+当您对修改满意后，使用 `git add` 添加更改的文件，并通过 `git commit` 在本地记录这些更改：
+
+```bash
+$ git add modified_file.py
+$ git commit -m "关于您所做更改的描述性信息。"
+```
+
+定期将您的代码副本与原始仓库同步是一个好习惯。这样可以快速适应上游变更：
+
+```bash
+$ git pull upstream main
+```
+
+使用以下命令将更改推送到您的账户：
+
+```bash
+$ git push -u origin 此处替换为您的描述性分支名称
+```
+
+6. 确认无误后，请访问您 GitHub 账户中的派生仓库页面。点击「Pull request」将您的更改提交给项目维护者审核。
+
+7. 如果维护者要求修改，这很正常——核心贡献者也会遇到这种情况！为了让所有人能在 Pull request 中看到变更，请在本地分支继续工作并将修改推送到您的派生仓库，这些变更会自动出现在 Pull request 中。
+
+### 测试
+
+我们提供了全面的测试套件来验证库行为和多个示例。库测试位于 [tests 文件夹](https://github.com/huggingface/diffusers/tree/main/tests)。
+
+我们推荐使用 `pytest` 和 `pytest-xdist`，因为它们速度更快。在仓库根目录下运行以下命令执行库测试：
+
+```bash
+$ python -m pytest -n auto --dist=loadfile -s -v ./tests/
+```
+
+实际上，这就是 `make test` 的实现方式！
+
+您可以指定更小的测试范围来仅验证您正在开发的功能。
+
+默认情况下会跳过耗时测试。设置 `RUN_SLOW` 环境变量为 `yes` 可运行这些测试。注意：这将下载数十 GB 的模型文件——请确保您有足够的磁盘空间、良好的网络连接或充足的耐心！
+
+```bash
+$ RUN_SLOW=yes python -m pytest -n auto --dist=loadfile -s -v ./tests/
+```
+
+我们也完全支持 `unittest`，运行方式如下：
+
+```bash
+$ python -m unittest discover -s tests -t . -v
+$ python -m unittest discover -s examples -t examples -v
+```
+
+### 将派生仓库的 main 分支与上游（HuggingFace）main 分支同步
+
+为避免向上游仓库发送引用通知（这会给相关 PR 添加注释并向开发者发送不必要的通知），在同步派生仓库的 main 分支时，请遵循以下步骤：
+1. 尽可能避免通过派生仓库的分支和 PR 来同步上游，而是直接合并到派生仓库的 main 分支
+2. 如果必须使用 PR，请在检出分支后执行以下操作：
+```bash
+$ git checkout -b 您的同步分支名称
+$ git pull --squash --no-commit upstream main
+$ git commit -m '提交信息（不要包含 GitHub 引用）'
+$ git push --set-upstream origin 您的分支名称
+```

+# 🧨 Diffusers伦理准则
+
+## 前言
+
+[Diffusers](https://huggingface.co/docs/diffusers/index)不仅提供预训练的diffusion模型，还是一个模块化工具箱，支持推理和训练功能。
+
+鉴于该技术在实际场景中的应用及其可能对社会产生的负面影响，我们认为有必要制定项目伦理准则，以指导Diffusers库的开发、用户贡献和使用规范。
+
+该技术涉及的风险仍在持续评估中，主要包括但不限于：艺术家版权问题、深度伪造滥用、不当情境下的色情内容生成、非自愿的人物模仿、以及加剧边缘群体压迫的有害社会偏见。我们将持续追踪风险，并根据社区反馈动态调整本准则。
+
+## 适用范围
+
+Diffusers社区将在项目开发中贯彻以下伦理准则，并协调社区贡献的整合方式，特别是在涉及伦理敏感议题的技术决策时。
+
+## 伦理准则
+
+以下准则具有普遍适用性，但我们主要在处理涉及伦理敏感问题的技术决策时实施。同时，我们承诺将根据技术发展带来的新兴风险持续调整这些原则：
+
+- **透明度**：我们承诺以透明方式管理PR（拉取请求），向用户解释决策依据，并公开技术选择过程。
+

+</a>
+
+> [!TIP]
+> 鉴于当前已出现针对图像生成Diffusion模型的成熟评估框架（如[HEIM](https://crfm.stanford.edu/helm/heim/latest/)、[T2I-Compbench](https://huggingface.co/papers/2307.06350)、[GenEval](https://huggingface.co/papers/2310.11513)），本文档部分内容已过时。
+
+像 [Stable Diffusion](https://huggingface.co/docs/diffusers/stable_diffusion) 这类生成模型的评估本质上是主观的。但作为开发者和研究者，我们经常需要在众多可能性中做出审慎选择。那么当面对不同生成模型（如 GANs、Diffusion 等）时，该如何决策？
+
+定性评估容易产生偏差，可能导致错误结论；而定量指标又未必能准确反映图像质量。因此，通常需要结合定性与定量评估来获得更可靠的模型选择依据。
+
+本文档将系统介绍扩散模型的定性与定量评估方法（非穷尽列举）。对于定量方法，我们将重点演示如何结合 `diffusers` 库实现这些评估。
+
+文档所示方法同样适用于评估不同[噪声调度器](https://huggingface.co/docs/diffusers/main/en/api/schedulers/overview)在固定生成模型下的表现差异。
+
+## 评估场景
+
+我们涵盖以下Diffusion模型管线的评估：
+
+- 文本引导图像生成（如 [`StableDiffusionPipeline`](https://huggingface.co/docs/diffusers/main/en/api/pipelines/stable_diffusion/text2img)）
+- 基于文本和输入图像的引导生成（如 [`StableDiffusionImg2ImgPipeline`](https://huggingface.co/docs/diffusers/main/en/api/pipelines/stable_diffusion/img2img) 和 [`StableDiffusionInstructPix2PixPipeline`](https://huggingface.co/docs/diffusers/main/en/api/pipelines/pix2pix)）
+- 类别条件图像生成模型(如 [`DiTPipeline`](https://huggingface.co/docs/diffusers/main/en/api/pipe))
+
+## 定性评估
+
+定性评估通常涉及对生成图像的人工评判。评估维度包括构图质量、图文对齐度和空间关系等方面。标准化的提示词能为这些主观指标提供统一基准。DrawBench和PartiPrompts是常用的定性评估提示词数据集，分别由[Imagen](https://imagen.research.google/)和[Parti](https://parti.research.google/)团队提出。
+
+根据[Parti官方网站](https://parti.research.google/)说明：
+
+> PartiPrompts (P2)是我们发布的包含1600多个英文提示词的丰富集合，可用于测量模型在不同类别和挑战维度上的能力。
+
+![parti-prompts](https://huggingface.co/datasets/diffusers/docs-images/resolve/main/evaluation_diffusion_models/parti-prompts.png)
+
+PartiPrompts包含以下字段：
+- Prompt（提示词）
+- Category（类别，如"抽象"、"世界知识"等）
+- Challenge（难度等级，如"基础"、"复杂"、"文字与符号"等）
+
+这些基准测试支持对不同图像生成模型进行并排人工对比评估。为此，🧨 Diffusers团队构建了**Open Parti Prompts**——一个基于Parti Prompts的社区驱动型定性评估基准，用于比较顶尖开源diffusion模型：
+- [Open Parti Prompts游戏](https://huggingface.co/spaces/OpenGenAI/open-parti-prompts)：展示10个parti提示词对应的4张生成图像，用户选择最符合提示的图片
+- [Open Parti Prompts排行榜](https://huggingface.co/spaces/OpenGenAI/parti-prompts-leaderboard)：对比当前最优开源diffusion模型的性能榜单
+
+为进行手动图像对比，我们演示如何使用`diffusers`处理部分PartiPrompts提示词。
+
+以下是从不同挑战维度（基础、复杂、语言结构、想象力、文字与符号）采样的提示词示例（使用[PartiPrompts作为数据集](https://huggingface.co/datasets/nateraw/parti-prompts)）：
+
+```python
+from datasets import load_dataset
+
+# prompts = load_dataset("nateraw/parti-prompts", split="train")
+# prompts = prompts.shuffle()
+# sample_prompts = [prompts[i]["Prompt"] for i in range(5)]
+
+# Fixing these sample prompts in the interest of reproducibility.
+sample_prompts = [
+    "a corgi",
+    "a hot air balloon with a yin-yang symbol, with the moon visible in the daytime sky",
+    "a car with no windows",
+    "a cube made of porcupine",
+    'The saying "BE EXCELLENT TO EACH OTHER" written on a red brick wall with a graffiti image of a green alien wearing a tuxedo. A yellow fire hydrant is on a sidewalk in the foreground.',
+]
+```
+
+现在我们可以使用Stable Diffusion（[v1-4 checkpoint](https://huggingface.co/CompVis/stable-diffusion-v1-4)）生成这些提示词对应的图像：
+
+```python
+import torch
+
+seed = 0
+generator = torch.manual_seed(seed)
+
+images = sd_pipeline(sample_prompts, num_images_per_prompt=1, generator=generator).images
+```
+
+![parti-prompts-14](https://huggingface.co/datasets/diffusers/docs-images/resolve/main/evaluation_diffusion_models/parti-prompts-14.png)
+
+我们也可以通过设置`num_images_per_prompt`参数来比较同一提示词生成的不同图像。使用不同检查点([v1-5](https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5))运行相同流程后，结果如下：
+
+![parti-prompts-15](https://huggingface.co/datasets/diffusers/docs-images/resolve/main/evaluation_diffusion_models/parti-prompts-15.png)
+
+当使用多个待评估模型为所有提示词生成若干图像后，这些结果将提交给人类评估员进行打分。有关DrawBench和PartiPrompts基准测试的更多细节，请参阅各自的论文。
+
+<Tip>
+
+在模型训练过程中查看推理样本有助于评估训练进度。我们的[训练脚本](https://github.com/huggingface/diffusers/tree/main/examples/)支持此功能，并额外提供TensorBoard和Weights & Biases日志记录功能。
+
+</Tip>
+
+## 定量评估
+
+本节将指导您如何评估三种不同的扩散流程，使用以下指标：
+- CLIP分数
+- CLIP方向相似度
+- FID（弗雷歇起始距离）
+
+### 文本引导图像生成
+
+[CLIP分数](https://huggingface.co/papers/2104.08718)用于衡量图像-标题对的匹配程度。CLIP分数越高表明匹配度越高🔼。该分数是对"匹配度"这一定性概念的量化测量，也可以理解为图像与标题之间的语义相似度。研究发现CLIP分数与人类判断具有高度相关性。
+
+首先加载[`StableDiffusionPipeline`]：
+
+```python
+from diffusers import StableDiffusionPipeline
+import torch
+
+model_ckpt = "CompVis/stable-diffusion-v1-4"
+sd_pipeline = StableDiffusionPipeline.from_pretrained(model_ckpt, torch_dtype=torch.float16).to("cuda")
+```
+
+使用多个提示词生成图像：
+
+```python
+prompts = [
+    "a photo of an astronaut riding a horse on mars",
+    "A high tech solarpunk utopia in the Amazon rainforest",
+    "A pikachu fine dining with a view to the Eiffel Tower",
+    "A mecha robot in a favela in expressionist style",
+    "an insect robot preparing a delicious meal",
+    "A small cabin on top of a snowy mountain in the style of Disney, artstation",
+]
+
+images = sd_pipeline(prompts, num_images_per_prompt=1, output_type="np").images
+
+print(images.shape)
+# (6, 512, 512, 3)
+```
+
+然后计算CLIP分数：
+
+```python
+from torchmetrics.functional.multimodal import clip_score
+from functools import partial
+
+clip_score_fn = partial(clip_score, model_name_or_path="openai/clip-vit-base-patch16")
+
+def calculate_clip_score(images, prompts):
+    images_int = (images * 255).astype("uint8")
+    clip_score = clip_score_fn(torch.from_numpy(images_int).permute(0, 3, 1, 2), prompts).detach()
+    return round(float(clip_score), 4)
+
+sd_clip_score = calculate_clip_score(images, prompts)
+print(f"CLIP分数: {sd_clip_score}")
+# CLIP分数: 35.7038
+```
+
+上述示例中，我们为每个提示生成一张图像。如果为每个提示生成多张图像，则需要计算每个提示生成图像的平均分数。
+
+当需要比较两个兼容[`StableDiffusionPipeline`]的检查点时，应在调用管道时传入生成器。首先使用[v1-4 Stable Diffusion检查点](https://huggingface.co/CompVis/stable-diffusion-v1-4)以固定种子生成图像：
+
+```python
+seed = 0
+generator = torch.manual_seed(seed)
+
+images = sd_pipeline(prompts, num_images_per_prompt=1, generator=generator, output_type="np").images
+```
+
+然后加载[v1-5检查点](https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5)生成图像：
+
+```python
+model_ckpt_1_5 = "stable-diffusion-v1-5/stable-diffusion-v1-5"
+sd_pipeline_1_5 = StableDiffusionPipeline.from_pretrained(model_ckpt_1_5, torch_dtype=torch.float16).to("cuda")
+
+images_1_5 = sd_pipeline_1_5(prompts, num_images_per_prompt=1, generator=generator, output_type="np").images
+```
+
+最后比较两者的CLIP分数：
+
+```python
+sd_clip_score_1_4 = calculate_clip_score(images, prompts)
+print(f"v-1-4版本的CLIP分数: {sd_clip_score_1_4}")
+# v-1-4版本的CLIP分数: 34.9102
+
+sd_clip_score_1_5 = calculate_clip_score(images_1_5, prompts)
+print(f"v-1-5版本的CLIP分数: {sd_clip_score_1_5}")
+# v-1-5版本的CLIP分数: 36.2137
+```
+
+结果表明[v1-5](https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5)检查点性能优于前代。但需注意，我们用于计算CLIP分数的提示词数量较少。实际评估时应使用更多样化且数量更大的提示词集。
+
+<Tip warning={true}>
+
+该分数存在固有局限性：训练数据中的标题是从网络爬取，并提取自图片关联的`alt`等标签。这些描述未必符合人类描述图像的方式，因此我们需要人工"设计"部分提示词。
+
+</Tip>
+
+### 图像条件式文本生成图像
+
+这种情况下，生成管道同时接受输入图像和文本提示作为条件。以[`StableDiffusionInstructPix2PixPipeline`]为例，该管道接收编辑指令作为输入提示，并接受待编辑的输入图像。
+
+示例图示：
+
+![编辑指令](https://huggingface.co/datasets/diffusers/docs-images/resolve/main/evaluation_diffusion_models/edit-instruction.png)
+
+评估此类模型的策略之一是测量两幅图像间变化的连贯性（通过[CLIP](https://huggingface.co/docs/transformers/model_doc/clip)定义）中两个图像之间的变化与两个图像描述之间的变化的一致性（如论文[《CLIP-Guided Domain Adaptation of Image Generators》](https://huggingface.co/papers/2108.00946)所示）。这被称为“**CLIP方向相似度**”。  
+
+- **描述1**对应输入图像（图像1），即待编辑的图像。  
+- **描述2**对应编辑后的图像（图像2），应反映编辑指令。  
+
+以下是示意图：  
+
+![edit-consistency](https://huggingface.co/datasets/diffusers/docs-images/resolve/main/evaluation_diffusion_models/edit-consistency.png)  
+
+我们准备了一个小型数据集来实现该指标。首先加载数据集：  
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("sayakpaul/instructpix2pix-demo", split="train")
+dataset.features
+```  
+
+```bash
+{'input': Value(dtype='string', id=None),
+ 'edit': Value(dtype='string', id=None),
+ 'output': Value(dtype='string', id=None),
+ 'image': Image(decode=True, id=None)}
+```  
+
+数据字段说明：  
+
+- `input`：与`image`对应的原始描述。  
+- `edit`：编辑指令。  
+- `output`：反映`edit`指令的修改后描述。  
+
+查看一个样本：  
+
+```python
+idx = 0
+print(f"Original caption: {dataset[idx]['input']}")
+print(f"Edit instruction: {dataset[idx]['edit']}")
+print(f"Modified caption: {dataset[idx]['output']}")
+```  
+
+```bash
+Original caption: 2. FAROE ISLANDS: An archipelago of 18 mountainous isles in the North Atlantic Ocean between Norway and Iceland, the Faroe Islands has 'everything you could hope for', according to Big 7 Travel. It boasts 'crystal clear waterfalls, rocky cliffs that seem to jut out of nowhere and velvety green hills'
+Edit instruction: make the isles all white marble
+Modified caption: 2. WHITE MARBLE ISLANDS: An archipelago of 18 mountainous white marble isles in the North Atlantic Ocean between Norway and Iceland, the White Marble Islands has 'everything you could hope for', according to Big 7 Travel. It boasts 'crystal clear waterfalls, rocky cliffs that seem to jut out of nowhere and velvety green hills'
+```  
+
+对应的图像：  
+
+```python
+dataset[idx]["image"]
+```  
+
+![edit-dataset](https://huggingface.co/datasets/diffusers/docs-images/resolve/main/evaluation_diffusion_models/edit-dataset.png)  
+
+我们将根据编辑指令修改数据集中的图像，并计算方向相似度。  
+
+首先加载[`StableDiffusionInstructPix2PixPipeline`]：  
+
+```python
+from diffusers import StableDiffusionInstructPix2PixPipeline
+
+instruct_pix2pix_pipeline = StableDiffusionInstructPix2PixPipeline.from_pretrained(
+    "timbrooks/instruct-pix2pix", torch_dtype=torch.float16
+).to("cuda")
+```  
+
+执行编辑操作：  
+
+```python
+import numpy as np
+
+
+def edit_image(input_image, instruction):
+    image = instruct_pix2pix_pipeline(
+        instruction,
+        image=input_image,
+        output_type="np",
+        generator=generator,
+    ).images[0]
+    return image
+
+input_images = []
+original_captions = []
+modified_captions = []
+edited_images = []
+
+for idx in range(len(dataset)):
+    input_image = dataset[idx]["image"]
+    edit_instruction = dataset[idx]["edit"]
+    edited_image = edit_image(input_image, edit_instruction)
+
+    input_images.append(np.array(input_image))
+    original_captions.append(dataset[idx]["input"])
+    modified_captions.append(dataset[idx]["output"])
+    edited_images.append(edited_image)
+```
+
+为测量方向相似度，我们首先加载CLIP的图像和文本编码器：
+
+```python
+from transformers import (
+    CLIPTokenizer,
+    CLIPTextModelWithProjection,
+    CLIPVisionModelWithProjection,
+    CLIPImageProcessor,
+)
+
+clip_id = "openai/clip-vit-large-patch14"
+tokenizer = CLIPTokenizer.from_pretrained(clip_id)
+text_encoder = CLIPTextModelWithProjection.from_pretrained(clip_id).to("cuda")
+image_processor = CLIPImageProcessor.from_pretrained(clip_id)
+image_encoder = CLIPVisionModelWithProjection.from_pretrained(clip_id).to("cuda")
+```
+
+注意我们使用的是特定CLIP检查点——`openai/clip-vit-large-patch14`，因为Stable Diffusion预训练正是基于此CLIP变体。详见[文档](https://huggingface.co/docs/transformers/model_doc/clip)。
+
+接着准备计算方向相似度的PyTorch `nn.Module`：
+
+```python
+import torch.nn as nn
+import torch.nn.functional as F
+
+
+class DirectionalSimilarity(nn.Module):
+    def __init__(self, tokenizer, text_encoder, image_processor, image_encoder):
+        super().__init__()
+        self.tokenizer = tokenizer
+        self.text_encoder = text_encoder
+        self.image_processor = image_processor
+        self.image_encoder = image_encoder
+
+    def preprocess_image(self, image):
+        image = self.image_processor(image, return_tensors="pt")["pixel_values"]
+        return {"pixel_values": image.to("cuda")}
+
+    def tokenize_text(self, text):
+        inputs = self.tokenizer(
+            text,
+            max_length=self.tokenizer.model_max_length,
+            padding="max_length",
+            truncation=True,
+            return_tensors="pt",
+        )
+        return {"input_ids": inputs.input_ids.to("cuda")}
+
+    def encode_image(self, image):
+        preprocessed_image = self.preprocess_image(image)
+        image_features = self.image_encoder(**preprocessed_image).image_embeds
+        image_features = image_features / image_features.norm(dim=1, keepdim=True)
+        return image_features
+
+    def encode_text(self, text):
+        tokenized_text = self.tokenize_text(text)
+        text_features = self.text_encoder(**tokenized_text).text_embeds
+        text_features = text_features / text_features.norm(dim=1, keepdim=True)
+        return text_features
+
+    def compute_directional_similarity(self, img_feat_one, img_feat_two, text_feat_one, text_feat_two):
+        sim_direction = F.cosine_similarity(img_feat_two - img_feat_one, text_feat_two - text_feat_one)
+        return sim_direction
+
+    def forward(self, image_one, image_two, caption_one, caption_two):
+        img_feat_one = self.encode_image(image_one)
+        img_feat_two = self.encode_image(image_two)
+        text_feat_one = self.encode_text(caption_one)
+        text_feat_two = self.encode_text(caption_two)
+        directional_similarity = self.compute_directional_similarity(
+            img_feat_one, img_feat_two, text_feat_one, text_feat_two
+        )
+        return directional_similarity
+```
+
+现在让我们使用`DirectionalSimilarity`模块：
+
+```python
+dir_similarity = DirectionalSimilarity(tokenizer, text_encoder, image_processor, image_encoder)
+scores = []
+
+for i in range(len(input_images)):
+    original_image = input_images[i]
+    original_caption = original_captions[i]
+    edited_image = edited_images[i]
+    modified_caption = modified_captions[i]
+
+    similarity_score = dir_similarity(original_image, edited_image, original_caption, modified_caption)
+    scores.append(float(similarity_score.detach().cpu()))
+
+print(f"CLIP方向相似度: {np.mean(scores)}")
+# CLIP方向相似度: 0.0797976553440094
+```
+
+与CLIP分数类似，CLIP方向相似度数值越高越好。
+
+需要注意的是，`StableDiffusionInstructPix2PixPipeline`提供了两个控制参数`image_guidance_scale`和`guidance_scale`来调节最终编辑图像的质量。建议您尝试调整这两个参数，观察它们对方向相似度的影响。
+
+我们可以扩展这个度量标准来评估原始图像与编辑版本的相似度，只需计算`F.cosine_similarity(img_feat_two, img_feat_one)`。对于这类编辑任务，我们仍希望尽可能保留图像的主要语义特征（即保持较高的相似度分数）。
+
+该度量方法同样适用于类似流程，例如[`StableDiffusionPix2PixZeroPipeline`](https://huggingface.co/docs/diffusers/main/en/api/pipelines/pix2pix_zero#diffusers.StableDiffusionPix2PixZeroPipeline)。
+
+<Tip>
+
+CLIP分数和CLIP方向相似度都依赖CLIP模型，可能导致评估结果存在偏差。
+
+</Tip>
+
+***扩展IS、FID（后文讨论）或KID等指标存在困难***，当被评估模型是在大型图文数据集（如[LAION-5B数据集](https://laion.ai/blog/laion-5b/)）上预训练时。因为这些指标的底层都使用了在ImageNet-1k数据集上预训练的InceptionNet来提取图像特征。Stable Diffusion的预训练数据集与InceptionNet的预训练数据集可能重叠有限，因此不适合作为特征提取器。
+
+***上述指标更适合评估类别条件模型***，例如[DiT](https://huggingface.co/docs/diffusers/main/en/api/pipelines/dit)。该模型是在ImageNet-1k类别条件下预训练的。
+这是9篇文档中的第8部分。
+
+### 基于类别的图像生成
+
+基于类别的生成模型通常是在带有类别标签的数据集（如[ImageNet-1k](https://huggingface.co/datasets/imagenet-1k)）上进行预训练的。评估这些模型的常用指标包括Fréchet Inception Distance（FID）、Kernel Inception Distance（KID）和Inception Score（IS）。本文档重点介绍FID（[Heusel等人](https://huggingface.co/papers/1706.08500)），并展示如何使用[`DiTPipeline`](https://huggingface.co/docs/diffusers/api/pipelines/dit)计算该指标，该管道底层使用了[DiT模型](https://huggingface.co/papers/2212.09748)。
+
+FID旨在衡量两组图像数据集的相似程度。根据[此资源](https://mmgeneration.readthedocs.io/en/latest/quick_run.html#fid)：
+
+> Fréchet Inception Distance是衡量两组图像数据集相似度的指标。研究表明其与人类对视觉质量的主观判断高度相关，因此最常用于评估生成对抗网络（GAN）生成样本的质量。FID通过计算Inception网络特征表示所拟合的两个高斯分布之间的Fréchet距离来实现。
+
+这两个数据集本质上是真实图像数据集和生成图像数据集（本例中为人工生成的图像）。FID通常基于两个大型数据集计算，但本文档将使用两个小型数据集进行演示。
+
+首先下载ImageNet-1k训练集中的部分图像：
+
+```python
+from zipfile import ZipFile
+import requests
+
+
+def download(url, local_filepath):
+    r = requests.get(url)
+    with open(local_filepath, "wb") as f:
+        f.write(r.content)
+    return local_filepath
+
+dummy_dataset_url = "https://hf.co/datasets/sayakpaul/sample-datasets/resolve/main/sample-imagenet-images.zip"
+local_filepath = download(dummy_dataset_url, dummy_dataset_url.split("/")[-1])
+
+with ZipFile(local_filepath, "r") as zipper:
+    zipper.extractall(".")
+```
+
+```python
+from PIL import Image
+import os
+import numpy as np
+
+dataset_path = "sample-imagenet-images"
+image_paths = sorted([os.path.join(dataset_path, x) for x in os.listdir(dataset_path)])
+
+real_images = [np.array(Image.open(path).convert("RGB")) for path in image_paths]
+```
+
+这些是来自以下ImageNet-1k类别的10张图像："cassette_player"、"chain_saw"（2张）、"church"、"gas_pump"（3张）、"parachute"（2张）和"tench"。
+
+<p align="center">
+    <img src="https://huggingface.co/datasets/diffusers/docs-images/resolve/main/evaluation_diffusion_models/real-images.png" alt="真实图像"><br>
+    <em>真实图像</em>
+</p>
+
+加载图像后，我们对其进行轻量级预处理以便用于FID计算：
+
+```python
+from torchvision.transforms import functional as F
+import torch
+

+def preprocess_image(image):

+    image = image.permute(0, 3, 1, 2) / 255.0
+    return F.center_crop(image, (256, 256))
+
+real_images = torch.stack([dit_pipeline.preprocess_image(image) for image in real_images])
+print(real_images.shape)
+# torch.Size([10, 3, 256, 256])
+```
+
+我们现在加载[`DiTPipeline`](https://huggingface.co/docs/diffusers/api/pipelines/dit)来生成基于上述类别的条件图像。
+
+```python
+from diffusers import DiTPipeline, DPMSolverMultistepScheduler
+
+dit_pipeline = DiTPipeline.from_pretrained("facebook/DiT-XL-2-256", torch_dtype=torch.float16)
+dit_pipeline.scheduler = DPMSolverMultistepScheduler.from_config(dit_pipeline.scheduler.config)
+dit_pipeline = dit_pipeline.to("cuda")
+
+seed = 0
+generator = torch.manual_seed(seed)
+
+
+words = [
+    "cassette player",
+    "chainsaw",
+    "chainsaw",
+    "church",
+    "gas pump",
+    "gas pump",
+    "gas pump",
+    "parachute",
+    "parachute",
+    "tench",
+]
+
+class_ids = dit_pipeline.get_label_ids(words)
+output = dit_pipeline(class_labels=class_ids, generator=generator, output_type="np")
+
+fake_images = output.images
+fake_images = torch.tensor(fake_images)
+fake_images = fake_images.permute(0, 3, 1, 2)
+print(fake_images.shape)
+# torch.Size([10, 3, 256, 256])
+```
+
+现在，我们可以使用[`torchmetrics`](https://torchmetrics.readthedocs.io/)计算FID分数。
+
+```python
+from torchmetrics.image.fid import FrechetInceptionDistance
+
+fid = FrechetInceptionDistance(normalize=True)
+fid.update(real_images, real=True)
+fid.update(fake_images, real=False)
+
+print(f"FID分数: {float(fid.compute())}")
+# FID分数: 177.7147216796875
+```
+
+FID分数越低越好。以下因素会影响FID结果：
+
+- 图像数量（包括真实图像和生成图像）
+- 扩散过程中引入的随机性
+- 扩散过程的推理步数
+- 扩散过程中使用的调度器
+
+对于最后两点，最佳实践是使用不同的随机种子和推理步数进行多次评估，然后报告平均结果。
+
+<Tip warning={true}>
+
+FID结果往往具有脆弱性，因为它依赖于许多因素：
+
+* 计算过程中使用的特定Inception模型
+* 计算实现的准确性
+* 图像格式（PNG和JPG的起点不同）
+
+需要注意的是，FID通常在比较相似实验时最有用，但除非作者仔细公开FID测量代码，否则很难复现论文结果。
+
+这些注意事项同样适用于其他相关指标，如KID和IS。
+
+</Tip>
+
+最后，让我们可视化检查这些`fake_images`。

+# 设计哲学
+
+🧨 Diffusers 提供**最先进**的预训练扩散模型支持多模态任务。
+其目标是成为推理和训练通用的**模块化工具箱**。
+
+我们致力于构建一个经得起时间考验的库，因此对API设计极为重视。
+
+简而言之，Diffusers 被设计为 PyTorch 的自然延伸。因此，我们的多数设计决策都基于 [PyTorch 设计原则](https://pytorch.org/docs/stable/community/design.html#pytorch-design-philosophy)。以下是核心原则：
+
+## 可用性优先于性能
+
+- 尽管 Diffusers 包含众多性能优化特性（参见[内存与速度优化](https://huggingface.co/docs/diffusers/optimization/fp16)），模型默认总是以最高精度和最低优化级别加载。因此除非用户指定，扩散流程(pipeline)默认在CPU上以float32精度初始化。这确保了跨平台和加速器的可用性，意味着运行本库无需复杂安装。
+- Diffusers 追求**轻量化**，仅有少量必需依赖，但提供诸多可选依赖以提升性能（如`accelerate`、`safetensors`、`onnx`等）。我们竭力保持库的轻量级特性，使其能轻松作为其他包的依赖项。
+- Diffusers 偏好简单、自解释的代码而非浓缩的"魔法"代码。这意味着lambda函数等简写语法和高级PyTorch操作符通常不被采用。
+
+## 简洁优于简易
+
+正如PyTorch所言：**显式优于隐式**，**简洁优于复杂**。这一哲学体现在库的多个方面：
+- 我们遵循PyTorch的API设计，例如使用[`DiffusionPipeline.to`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.to)让用户自主管理设备。
+- 明确的错误提示优于静默纠正错误输入。Diffusers 旨在教育用户，而非单纯降低使用难度。
+- 暴露复杂的模型与调度器(scheduler)交互逻辑而非内部魔法处理。调度器/采样器与扩散模型分离且相互依赖最小化，迫使用户编写展开的去噪循环。但这种分离便于调试，并赋予用户更多控制权来调整去噪过程或切换模型/调度器。
+- 扩散流程中独立训练的组件（如文本编码器、UNet、变分自编码器）各有专属模型类。这要求用户处理组件间交互，且序列化格式将组件分存不同文件。但此举便于调试和定制，得益于组件分离，DreamBooth或Textual Inversion训练变得极为简单。
+
+## 可定制与贡献友好优于抽象
+
+库的大部分沿用了[Transformers库](https://github.com/huggingface/transformers)的重要设计原则：宁要重复代码，勿要仓促抽象。这一原则与[DRY原则](https://en.wikipedia.org/wiki/Don%27t_repeat_yourself)形成鲜明对比。
+
+简言之，正如Transformers对建模文件的做法，Diffusers对流程(pipeline)和调度器(scheduler)保持极低抽象度与高度自包含代码。函数、长代码块甚至类可能在多文件中重复，初看像是糟糕的松散设计。但该设计已被Transformers证明极其成功，对社区驱动的开源机器学习库意义重大：
+- 机器学习领域发展迅猛，范式、模型架构和算法快速迭代，难以定义长效代码抽象。
+- ML从业者常需快速修改现有代码进行研究，因此偏好自包含代码而非多重抽象。
+- 开源库依赖社区贡献，必须构建易于参与的代码库。抽象度越高、依赖越复杂、可读性越差，贡献难度越大。过度抽象的库会吓退贡献者。若贡献不会破坏核心功能，不仅吸引新贡献者，也更便于并行审查和修改。
+
+Hugging Face称此设计为**单文件政策**——即某个类的几乎所有代码都应写在单一自包含文件中。更多哲学探讨可参阅[此博文](https://huggingface.co/blog/transformers-design-philosophy)。
+
+Diffusers对流程和调度器完全遵循该哲学，但对diffusion模型仅部分适用。原因在于多数扩散流程（如[DDPM](https://huggingface.co/docs/diffusers/api/pipelines/ddpm)、[Stable Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/overview#stable-diffusion-pipelines)、[unCLIP (DALL·E 2)](https://huggingface.co/docs/diffusers/api/pipelines/unclip)和[Imagen](https://imagen.research.google/)）都基于相同扩散模型——[UNet](https://huggingface.co/docs/diffusers/api/models/unet2d-cond)。
+
+现在您应已理解🧨 Diffusers的设计理念🤗。我们力求在全库贯彻这些原则，但仍存在少数例外或欠佳设计。如有反馈，我们❤️欢迎在[GitHub提交](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feedback.md&title=)。
+
+## 设计哲学细节
+
+现在深入探讨设计细节。Diffusers主要包含三类：[流程(pipeline)](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines)、[模型](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models)和[调度器(scheduler)](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers)。以下是各类的具体设计决策。
+
+### 流程(Pipelines)
+
+流程设计追求易用性（因此不完全遵循[*简洁优于简易*](#简洁优于简易)），不要求功能完备，应视为使用[模型](#模型)和[调度器](#调度器schedulers)进行推理的示例。
+
+遵循原则：
+- 采用单文件政策。所有流程位于src/diffusers/pipelines下的独立目录。一个流程文件夹对应一篇扩散论文/项目/发布。如[`src/diffusers/pipelines/stable-diffusion`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines/stable_diffusion)可包含多个流程文件。若流程功能相似，可使用[# Copied from机制](https://github.com/huggingface/diffusers/blob/125d783076e5bd9785beb05367a2d2566843a271/src/diffusers/pipelines/stable_diffusion/pipeline_stable_diffusion_img2img.py#L251)。
+- 所有流程继承[`DiffusionPipeline`]。
+- 每个流程由不同模型和调度器组件构成，这些组件记录于[`model_index.json`文件](https://huggingface.co/stable-diffusion-v1-5/stable-diffusion-v1-5/blob/main/model_index.json)，可通过同名属性访问，并可用[`DiffusionPipeline.components`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.components)在流程间共享。
+- 所有流程应能通过[`DiffusionPipeline.from_pretrained`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.from_pretrained)加载。
+- 流程**仅**用于推理。
+- 流程代码应具备高可读性、自解释性和易修改性。
+- 流程应设计为可相互构建，便于集成到高层API。
+- 流程**非**功能完备的用户界面。完整UI推荐[InvokeAI](https://github.com/invoke-ai/InvokeAI)、[Diffuzers](https://github.com/abhishekkrthakur/diffuzers)或[lama-cleaner](https://github.com/Sanster/lama-cleaner)。
+- 每个流程应通过唯一的`__call__`方法运行，且参数命名应跨流程统一。
+- 流程应以其解决的任务命名。
+- 几乎所有新diffusion流程都应在新文件夹/文件中实现。
+
+### 模型
+
+模型设计为可配置的工具箱，是[PyTorch Module类](https://pytorch.org/docs/stable/generated/torch.nn.Module.html)的自然延伸，仅部分遵循**单文件政策**。
+
+遵循原则：
+- 模型对应**特定架构类型**。如[`UNet2DConditionModel`]类适用于所有需要2D图像输入且受上下文调节的UNet变体。
+- 所有模型位于[`src/diffusers/models`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models)，每种架构应有独立文件，如[`unets/unet_2d_condition.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/unets/unet_2d_condition.py)、[`transformers/transformer_2d.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/transformers/transformer_2d.py)等。
+- 模型**不**采用单文件政策，应使用小型建模模块如[`attention.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention.py)、[`resnet.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/resnet.py)、[`embeddings.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/embeddings.py)等。**注意**：这与Transformers的建模文件截然不同，表明模型未完全遵循单文件政策。
+- 模型意图暴露复杂度（类似PyTorch的`Module`类），并提供明确错误提示。
+- 所有模型继承`ModelMixin`和`ConfigMixin`。
+- 当不涉及重大代码变更、保持向后兼容性且显著提升内存/计算效率时，可对模型进行性能优化。
+- 模型默认应具备最高精度和最低性能设置。
+- 若新模型检查点可归类为现有架构，应适配现有架构而非新建文件。仅当架构根本性不同时才创建新文件。
+- 模型设计应便于未来扩展。可通过限制公开函数参数、配置参数和"预见"变更实现。例如：优先采用可扩展的`string`类型参数而非布尔型`is_..._type`参数。对现有架构的修改应保持最小化。
+- 模型设计需在代码可读性与多检查点支持间权衡。多数情况下应适配现有类，但某些例外（如[UNet块](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/unets/unet_2d_blocks.py)和[注意力处理器](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py)）需新建类以保证长期可读性。
+
+### 调度器(Schedulers)
+
+调度器负责引导推理去噪过程及定义训练噪声计划。它们设计为独立的可加载配置类，严格遵循**单文件政策**。
+
+遵循原则：
+- 所有调度器位于[`src/diffusers/schedulers`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers)。
+- 调度器**禁止**从大型工具文件导入，必须保持高度自包含。
+- 一个调度器Python文件对应一种算法（如论文定义的算法）。
+- 若调度器功能相似，可使用`# Copied from`机制。
+- 所有调度器继承`SchedulerMixin`和`ConfigMixin`。
+- 调度器可通过[`ConfigMixin.from_config`](https://huggingface.co/docs/diffusers/main/en/api/configuration#diffusers.ConfigMixin.from_config)轻松切换（详见[此处](../using-diffusers/schedulers)）。
+- 每个调度器必须包含`set_num_inference_steps`和`step`函数。在每次去噪过程前（即调用`step(...)`前）必须调用`set_num_inference_steps(...)`。
+- 每个调度器通过`timesteps`属性暴露需要"循环"的时间步，这是模型将被调用的时间步数组。
+- `step(...)`函数接收模型预测输出和"当前"样本(x_t)，返回"前一个"略去噪的样本(x_t-1)。
+- 鉴于扩散调度器的复杂性，`step`函数不暴露全部细节，可视为"黑盒"。
+- 几乎所有新调度器都应在新文件中实现。

+# AutoPipelineBlocks
+
+[`~modular_pipelines.AutoPipelineBlocks`] 是一种包含支持不同工作流程的块的多块类型。它根据运行时提供的输入自动选择要运行的子块。这通常用于将多个工作流程（文本到图像、图像到图像、修复）打包到一个管道中以便利。
+
+本指南展示如何创建 [`~modular_pipelines.AutoPipelineBlocks`]。
+
+创建三个 [`~modular_pipelines.ModularPipelineBlocks`] 用于文本到图像、图像到图像和修复。这些代表了管道中可用的不同工作流程。

+创建一个包含子块类及其对应块名称列表的[`~modular_pipelines.AutoPipelineBlocks`]类。
+
+你还需要包括`block_trigger_inputs`，一个触发相应块的输入名称列表。如果在运行时提供了触发输入，则选择该块运行。使用`None`来指定如果未检测到触发输入时运行的默认块。
+
+最后，重要的是包括一个`description`，清楚地解释哪些输入触发哪些工作流。这有助于用户理解如何运行特定的工作流。
+
+```py
+from diffusers.modular_pipelines import AutoPipelineBlocks
+
+class AutoImageBlocks(AutoPipelineBlocks):
+    # 选择子块类的列表
+    block_classes = [block_inpaint_cls, block_i2i_cls, block_t2i_cls]
+    # 每个块的名称，顺序相同
+    block_names = ["inpaint", "img2img", "text2img"]
+    # 决定运行哪个块的触发输入
+    # - "mask" 触发修复工作流
+    # - "image" 触发img2img工作流（但仅在未提供mask时）
+    # - 如果以上都没有，运行text2img工作流（默认）
+    block_trigger_inputs = ["mask", "image", None]
+    # 对于AutoPipelineBlocks来说，描述极其重要
+
+    def description(self):
+        return (
+            "Pipeline generates images given different types of conditions!\n"
+            + "This is an auto pipeline block that works for text2img, img2img and inpainting tasks.\n"
+            + " - inpaint workflow is run when `mask` is provided.\n"
+            + " - img2img workflow is run when `image` is provided (but only when `mask` is not provided).\n"
+            + " - text2img workflow is run when neither `image` nor `mask` is provided.\n"
+        )
+```
+
+包含`description`以避免任何关于如何运行块和需要什么输入的混淆**非常**重要。虽然[`~modular_pipelines.AutoPipelineBlocks`]很方便，但如果它没有正确解释，其条件逻辑可能难以理解。
+
+创建`AutoImageBlocks`的一个实例。
+
+```py
+auto_blocks = AutoImageBlocks()
+```
+
+对于更复杂的组合，例如在更大的管道中作为子块使用的嵌套[`~modular_pipelines.AutoPipelineBlocks`]块，使用[`~modular_pipelines.SequentialPipelineBlocks.get_execution_blocks`]方法根据你的输入提取实际运行的块。
+
+```py
+auto_blocks.get_execution_blocks("mask")
+```

+# 组件管理器
+
+[`ComponentsManager`] 是 Modular Diffusers 的模型注册和管理系统。它添加和跟踪模型，存储有用的元数据（模型大小、设备放置、适配器），防止重复模型实例，并支持卸载。
+
+本指南将展示如何使用 [`ComponentsManager`] 来管理组件和设备内存。
+
+## 添加组件
+
+[`ComponentsManager`] 应与 [`ModularPipeline`] 一起创建，在 [`~ModularPipeline.from_pretrained`] 或 [`~ModularPipelineBlocks.init_pipeline`] 中。
+
+> [!TIP]
+> `collection` 参数是可选的，但可以更轻松地组织和管理组件。
+
+<hfoptions id="create">
+<hfoption id="from_pretrained">
+
+```py
+from diffusers import ModularPipeline, ComponentsManager
+
+comp = ComponentsManager()
+pipe = ModularPipeline.from_pretrained("YiYiXu/modular-demo-auto", components_manager=comp, collection="test1")
+```
+
+</hfoption>
+<hfoption id="init_pipeline">
+
+```py
+from diffusers import ComponentsManager
+from diffusers.modular_pipelines import SequentialPipelineBlocks
+from diffusers.modular_pipelines.stable_diffusion_xl import TEXT2IMAGE_BLOCKS
+
+t2i_blocks = SequentialPipelineBlocks.from_blocks_dict(TEXT2IMAGE_BLOCKS)
+
+modular_repo_id = "YiYiXu/modular-loader-t2i-0704"
+components = ComponentsManager()
+t2i_pipeline = t2i_blocks.init_pipeline(modular_repo_id, components_manager=components)
+```
+
+</hfoption>
+</hfoptions>
+
+组件仅在调用 [`~ModularPipeline.load_components`] 或 [`~ModularPipeline.load_default_components`] 时加载和注册。以下示例使用 [`~ModularPipeline.load_default_components`] 创建第二个管道，重用第一个管道的所有组件，并将其分配到不同的集合。
+
+```py
+pipe.load_default_components()
+pipe2 = ModularPipeline.from_pretrained("YiYiXu/modular-demo-auto", components_manager=comp, collection="test2")
+```
+
+使用 [`~ModularPipeline.null_component_names`] 属性来识别需要加载的任何组件，使用 [`~ComponentsManager.get_components_by_names`] 检索它们，然后调用 [`~ModularPipeline.update_components`] 来添加缺失的组件。
+
+```py
+pipe2.null_component_names 
+['text_encoder', 'text_encoder_2', 'tokenizer', 'tokenizer_2', 'image_encoder', 'unet', 'vae', 'scheduler', 'controlnet']
+
+comp_dict = comp.get_components_by_names(names=pipe2.null_component_names)
+pipe2.update_components(**comp_dict)
+```
+
+要添加单个组件，请使用 [`~ComponentsManager.add`] 方法。这会使用唯一 id 注册一个组件。
+
+```py
+from diffusers import AutoModel
+
+text_encoder = AutoModel.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder")
+component_id = comp.add("text_encoder", text_encoder)
+comp
+```
+
+使用 [`~ComponentsManager.remove`] 通过其 id 移除一个组件。
+
+```py
+comp.remove("text_encoder_139917733042864")
+```
+
+## 检索组件
+
+[`ComponentsManager`] 提供了几种方法来检索已注册的组件。
+
+### get_one
+
+[`~ComponentsManager.get_one`] 方法返回单个组件，并支持对 `name` 参数进行模式匹配。如果多个组件匹配，[`~ComponentsManager.get_one`] 会返回错误。
+
+| 模式       | 示例                             | 描述                                   |
+|-------------|----------------------------------|-------------------------------------------|
+| exact       | `comp.get_one(name="unet")`      | 精确名称匹配                          |
+| wildcard    | `comp.get_one(name="unet*")`     | 名称以 "unet" 开头                |
+| exclusion   | `comp.get_one(name="!unet")`     | 排除名为 "unet" 的组件           |
+| or          | `comp.get_one(name="unet&#124;vae")`  | 名称为 "unet" 或 "vae"                   |
+
+[`~ComponentsManager.get_one`] 还通过 `collection` 参数或 `load_id` 参数过滤组件。
+
+```py
+comp.get_one(name="unet", collection="sdxl")
+```
+
+### get_components_by_names
+
+[`~ComponentsManager.get_components_by_names`] 方法接受一个名称列表，并返回一个将名称映射到组件的字典。这在 [`ModularPipeline`] 中特别有用，因为它们提供了所需组件名称的列表，并且返回的字典可以直接传递给 [`~ModularPipeline.update_components`]。
+
+```py
+component_dict = comp.get_components_by_names(names=["text_encoder", "unet", "vae"])
+{"text_encoder": component1, "unet": component2, "vae": component3}
+```
+
+## 重复检测
+
+建议使用 [`ComponentSpec`] 加载模型组件，以分配具有唯一 id 的组件，该 id 编码了它们的加载参数。这允许 [`ComponentsManager`] 自动检测并防止重复的模型实例，即使不同的对象代表相同的底层检查点。
+
+```py
+from diffusers import ComponentSpec, ComponentsManager
+from transformers import CLIPTextModel
+
+comp = ComponentsManager()
+
+# 为第一个文本编码器创建 ComponentSpec
+spec = ComponentSpec(name="text_encoder", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder", type_hint=AutoModel)
+# 为重复的文本编码器创建 ComponentSpec（它是相同的检查点，来自相同的仓库/子文件夹）
+spec_duplicated = ComponentSpec(name="text_encoder_duplicated", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder", ty
+pe_hint=CLIPTextModel)
+
+# 加载并添加两个组件 - 管理器会检测到它们是同一个模型
+comp.add("text_encoder", spec.load())
+comp.add("text_encoder_duplicated", spec_duplicated.load())
+```
+
+这会返回一个警告，附带移除重复项的说明。

+ComponentsManager: adding component 'text_encoder_duplicated_139917580682672', but it has duplicate load_id 'stabilityai/stable-diffusion-xl-base-1.0|text_encoder|null|null' with existing components: text_encoder_139918506246832. To remove a duplicate, call `components_manager.remove('<component_id>')`.

+
+您也可以不使用 [`ComponentSpec`] 添加组件，并且在大多数情况下，即使您以不同名称添加相同组件，重复检测仍然有效。
+
+然而，当您将相同组件加载到不同对象时，[`ComponentManager`] 无法检测重复项。在这种情况下，您应该使用 [`ComponentSpec`] 加载模型。
+
+```py
+text_encoder_2 = AutoModel.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder")
+comp.add("text_encoder", text_encoder_2)
+'text_encoder_139917732983664'
+```
+
+## 集合
+
+集合是为组件分配的标签，用于更好的组织和管理。使用 [`~ComponentsManager.add`] 中的 `collection` 参数将组件添加到集合中。
+
+每个集合中只允许每个名称有一个组件。添加第二个同名组件会自动移除第一个组件。
+
+```py
+from diffusers import ComponentSpec, ComponentsManager
+
+comp = ComponentsManager()
+# 为第一个 UNet 创建 ComponentSpec
+spec = ComponentSpec(name="unet", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="unet", type_hint=AutoModel)
+# 为另一个 UNet 创建 ComponentSpec
+spec2 = ComponentSpec(name="unet", repo="RunDiffusion/Juggernaut-XL-v9", subfolder="unet", type_hint=AutoModel, variant="fp16")
+
+# 将两个 UNet 添加到同一个集合 - 第二个将替换第一个
+comp.add("unet", spec.load(), collection="sdxl")
+comp.add("unet", spec2.load(), collection="sdxl")
+```
+
+这使得在基于节点的系统中工作变得方便，因为您可以：
+
+- 使用 `collection` 标签标记所有从一个节点加载的模型。
+- 当新检查点以相同名称加载时自动替换模型。
+- 当节点被移除时批量删除集合中的所有模型。
+
+## 卸载
+
+[`~ComponentsManager.enable_auto_cpu_offload`] 方法是一种全局卸载策略，适用于所有模型，无论哪个管道在使用它们。一旦启用，您无需担心设备放置，如果您添加或移除组件。
+
+```py
+comp.enable_auto_cpu_offload(device="cuda")
+```
+
+所有模型开始时都在 CPU 上，[`ComponentsManager`] 在需要它们之前将它们移动到适当的设备，并在 GPU 内存不足时将其他模型移回 CPU。
+
+您可以设置自己的规则来决定哪些模型要卸载。
