+# Diffusers Benchmarks
+
+Welcome to Diffusers Benchmarks. These benchmarks are use to obtain latency and memory information of the most popular models across different scenarios such as:
+
+* Base case i.e., when using `torch.bfloat16` and `torch.nn.functional.scaled_dot_product_attention`.
+* Base + `torch.compile()`
+* NF4 quantization
+* Layerwise upcasting
+
+Instead of full diffusion pipelines, only the forward pass of the respective model classes (such as `FluxTransformer2DModel`) is tested with the real checkpoints (such as `"black-forest-labs/FLUX.1-dev"`). 
+
+The entrypoint to running all the currently available benchmarks is in `run_all.py`. However, one can run the individual benchmarks, too, e.g., `python benchmarking_flux.py`. It should produce a CSV file containing various information about the benchmarks run.
+
+The benchmarks are run on a weekly basis and the CI is defined in [benchmark.yml](../.github/workflows/benchmark.yml).
+
+## Running the benchmarks manually
+
+First set up `torch` and install `diffusers` from the root of the directory:
+
+```py
+pip install -e ".[quality,test]"
+```
+
+Then make sure the other dependencies are installed:
+
+```sh
+cd benchmarks/
+pip install -r requirements.txt
+```
+
+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).
+
+Then you can either launch the entire benchmarking suite by running:
+
+```sh
+python run_all.py
+```
+
+Or, you can run the individual benchmarks.
+
+## Customizing the benchmarks
+
+We define "scenarios" to cover the most common ways in which these models are used. You can
+define a new scenario, modifying an existing benchmark file:
+
+```py
+BenchmarkScenario(
+    name=f"{CKPT_ID}-bnb-8bit",
+    model_cls=FluxTransformer2DModel,
+    model_init_kwargs={
+        "pretrained_model_name_or_path": CKPT_ID,
+        "torch_dtype": torch.bfloat16,
+        "subfolder": "transformer",
+        "quantization_config": BitsAndBytesConfig(load_in_8bit=True),
+    },
+    get_model_input_dict=partial(get_input_dict, device=torch_device, dtype=torch.bfloat16),
+    model_init_fn=model_init_fn,
+)
+```
+
+You can also configure a new model-level benchmark and add it to the existing suite. To do so, just defining a valid benchmarking file like `benchmarking_flux.py` should be enough.
+
+Happy benchmarking 🧨

+# SkyReels-V2: Infinite-length Film Generative model
+
+[SkyReels-V2](https://huggingface.co/papers/2504.13074) by the SkyReels Team.
+
+*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).*

+### A _Visual_ Demonstration
+
+        An example with these parameters:
+        base_num_frames=97, num_frames=97, num_inference_steps=30, ar_step=5, causal_block_size=5
+
+        vae_scale_factor_temporal -> 4
+        num_latent_frames: (97-1)//vae_scale_factor_temporal+1 = 25 frames -> 5 blocks of 5 frames each
+
+        base_num_latent_frames = (97-1)//vae_scale_factor_temporal+1 = 25 → blocks = 25//5 = 5 blocks
+        This 5 blocks means the maximum context length of the model is 25 frames in the latent space.
+
+        Asynchronous Processing Timeline:
+        ┌─────────────────────────────────────────────────────────────────┐
+        │ 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
+        ┌──── Iteration 1 (frames 1-97) ────┐
+        │ Processing window: 97 frames      │ → 5 blocks, async processing
+        │ Generates: frames 1-97            │
+        └───────────────────────────────────┘
+                    ┌────── Iteration 2 (frames 81-177) ──────┐
+                    │ Processing window: 97 frames            │
+                    │ Overlap: 17 frames (81-97) from prev    │ → 5 blocks, async processing
+                    │ Generates: frames 98-177                │
+                    └─────────────────────────────────────────┘
+                                ┌────── Iteration 3 (frames 161-257) ──────┐
+                                │ Processing window: 97 frames             │
+                                │ Overlap: 17 frames (161-177) from prev   │ → 5 blocks, async processing
+                                │ Generates: frames 178-257                │
+                                └──────────────────────────────────────────┘
+
+        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:
+        ┌──────────────────────────────────────────────┐
+        │ 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,

+        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.

+
+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.

 # GLIGEN (Grounded Language-to-Image Generation)
 
 The GLIGEN model was created by researchers and engineers from [University of Wisconsin-Madison, Columbia University, and Microsoft](https://github.com/gligen/GLIGEN). The [`StableDiffusionGLIGENPipeline`] and [`StableDiffusionGLIGENTextImagePipeline`] can generate photorealistic images conditioned on grounding inputs. Along with text and bounding boxes with [`StableDiffusionGLIGENPipeline`], if input images are given, [`StableDiffusionGLIGENTextImagePipeline`] can insert objects described by text at the region defined by bounding boxes. Otherwise, it'll generate an image described by the caption/prompt and insert objects described by text at the region defined by bounding boxes. It's trained on COCO2014D and COCO2014CD datasets, and the model uses a frozen CLIP ViT-L/14 text encoder to condition itself on grounding inputs.

 # Safe Stable Diffusion
 
 Safe Stable Diffusion was proposed in [Safe Latent Diffusion: Mitigating Inappropriate Degeneration in Diffusion Models](https://huggingface.co/papers/2211.05105) and mitigates inappropriate degeneration from Stable Diffusion models because they're trained on unfiltered web-crawled datasets. For instance Stable Diffusion may unexpectedly generate nudity, violence, images depicting self-harm, and otherwise offensive content. Safe Stable Diffusion is an extension of Stable Diffusion that drastically reduces this type of content.

 # 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.
+- easy inference with only a few lines of code
+- flexibility to mix-and-match pipeline components (models, schedulers)
+- loading and using adapters like LoRA

+# AutoPipelineBlocks
+
+<Tip warning={true}>
+
+🧪 **Experimental Feature**: Modular Diffusers is an experimental feature we are actively developing. The API may be subject to breaking changes.
+
+</Tip>
+
+`AutoPipelineBlocks` is a subclass of `ModularPipelineBlocks`. It is a multi-block that automatically selects which sub-blocks to run based on the inputs provided at runtime, creating conditional workflows that adapt to different scenarios. The main purpose is convenience and portability - for developers, you can package everything into one workflow, making it easier to share and use.
+
+In this tutorial, we will show you how to create an `AutoPipelineBlocks` and learn more about how the conditional selection works.
+
+<Tip>
+
+Other types of multi-blocks include [SequentialPipelineBlocks](sequential_pipeline_blocks.md) (for linear workflows) and [LoopSequentialPipelineBlocks](loop_sequential_pipeline_blocks.md) (for iterative workflows). For information on creating individual blocks, see the [PipelineBlock guide](pipeline_block.md).
+
+Additionally, like all `ModularPipelineBlocks`, `AutoPipelineBlocks` are definitions/specifications, not runnable pipelines. You need to convert them into a `ModularPipeline` to actually execute them. For information on creating and running pipelines, see the [Modular Pipeline guide](modular_pipeline.md).
+
+</Tip>
+
+For example, you might want to support text-to-image and image-to-image tasks. Instead of creating two separate pipelines, you can create an `AutoPipelineBlocks` that automatically chooses the workflow based on whether an `image` input is provided.
+
+Let's see an example. We'll use the helper function from the [PipelineBlock guide](./pipeline_block.md) to create our blocks:
+
+**Helper Function**
+
+```py
+from diffusers.modular_pipelines import PipelineBlock, InputParam, OutputParam
+import torch
+
+def make_block(inputs=[], intermediate_inputs=[], intermediate_outputs=[], block_fn=None, description=None):
+    class TestBlock(PipelineBlock):
+        model_name = "test"
+        
+        @property
+        def inputs(self):
+            return inputs
+            
+        @property
+        def intermediate_inputs(self):
+            return intermediate_inputs
+            
+        @property
+        def intermediate_outputs(self):
+            return intermediate_outputs
+            
+        @property
+        def description(self):
+            return description if description is not None else ""
+            
+        def __call__(self, components, state):
+            block_state = self.get_block_state(state)
+            if block_fn is not None:
+                block_state = block_fn(block_state, state)
+            self.set_block_state(state, block_state)
+            return components, state
+    
+    return TestBlock
+```
+
+Now let's create a dummy `AutoPipelineBlocks` that includes dummy text-to-image, image-to-image, and inpaint pipelines.
+
+
+```py
+from diffusers.modular_pipelines import AutoPipelineBlocks 
+
+# These are dummy blocks and we only focus on "inputs" for our purpose
+inputs = [InputParam(name="prompt")]
+# block_fn prints out which workflow is running so we can see the execution order at runtime
+block_fn = lambda x, y: print("running the text-to-image workflow")
+block_t2i_cls = make_block(inputs=inputs, block_fn=block_fn, description="I'm a text-to-image workflow!")
+
+inputs = [InputParam(name="prompt"), InputParam(name="image")]
+block_fn = lambda x, y: print("running the image-to-image workflow")
+block_i2i_cls = make_block(inputs=inputs, block_fn=block_fn, description="I'm a image-to-image workflow!")
+
+inputs = [InputParam(name="prompt"), InputParam(name="image"), InputParam(name="mask")]
+block_fn = lambda x, y: print("running the inpaint workflow")
+block_inpaint_cls = make_block(inputs=inputs, block_fn=block_fn, description="I'm a inpaint workflow!")
+
+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
+    @property
+    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"
+        )
+
+# Create the blocks
+auto_blocks = AutoImageBlocks()
+# convert to pipeline
+auto_pipeline = auto_blocks.init_pipeline()
+```
+
+Now we have created an `AutoPipelineBlocks` that contains 3 sub-blocks. Notice the warning message at the top - this automatically appears in every `ModularPipelineBlocks` that contains `AutoPipelineBlocks` to remind end users that dynamic block selection happens at runtime. 
+
+```py
+AutoImageBlocks(
+  Class: AutoPipelineBlocks
+
+  ====================================================================================================
+  This pipeline contains blocks that are selected at runtime based on inputs.
+  Trigger Inputs: ['mask', 'image']
+  ====================================================================================================
+
+
+  Description: Pipeline generates images given different types of conditions!
+      This is an auto pipeline block that works for text2img, img2img and inpainting tasks.
+       - inpaint workflow is run when `mask` is provided.
+       - img2img workflow is run when `image` is provided (but only when `mask` is not provided).
+       - text2img workflow is run when neither `image` nor `mask` is provided.
+      
+
+
+  Sub-Blocks:
+    • inpaint [trigger: mask] (TestBlock)
+       Description: I'm a inpaint workflow!
+
+    • img2img [trigger: image] (TestBlock)
+       Description: I'm a image-to-image workflow!
+
+    • text2img [default] (TestBlock)
+       Description: I'm a text-to-image workflow!
+
+)
+```
+
+Check out the documentation with `print(auto_pipeline.doc)`:
+
+```py
+>>> print(auto_pipeline.doc)
+class AutoImageBlocks
+
+  Pipeline generates images given different types of conditions!
+  This is an auto pipeline block that works for text2img, img2img and inpainting tasks.
+   - inpaint workflow is run when `mask` is provided.
+   - img2img workflow is run when `image` is provided (but only when `mask` is not provided).
+   - text2img workflow is run when neither `image` nor `mask` is provided.
+
+  Inputs:
+
+      prompt (`None`, *optional*):
+
+      image (`None`, *optional*):
+
+      mask (`None`, *optional*):
+```
+
+There is a fundamental trade-off of AutoPipelineBlocks: it trades clarity for convenience. While it is really easy for packaging multiple workflows, it can become confusing without proper documentation. e.g. if we just throw a pipeline at you and tell you that it contains 3 sub-blocks and takes 3 inputs `prompt`, `image` and `mask`, and ask you to run an image-to-image workflow: if you don't have any prior knowledge on how these pipelines work, you would be pretty clueless, right?
+
+This pipeline we just made though, has a docstring that shows all available inputs and workflows and explains how to use each with different inputs. So it's really helpful for users. For example, it's clear that you need to pass `image` to run img2img. This is why the description field is absolutely critical for AutoPipelineBlocks. We highly recommend you to explain the conditional logic very well for each `AutoPipelineBlocks` you would make. We also recommend to always test individual pipelines first before packaging them into AutoPipelineBlocks. 
+
+Let's run this auto pipeline with different inputs to see if the conditional logic works as described. Remember that we have added `print` in each `PipelineBlock`'s `__call__` method to print out its workflow name, so it should be easy to tell which one is running:
+
+```py
+>>> _ = auto_pipeline(image="image", mask="mask")
+running the inpaint workflow
+>>> _ = auto_pipeline(image="image")
+running the image-to-image workflow
+>>> _ = auto_pipeline(prompt="prompt")
+running the text-to-image workflow
+>>> _ = auto_pipeline(image="prompt", mask="mask")
+running the inpaint workflow
+```
+
+However, even with documentation, it can become very confusing when AutoPipelineBlocks are combined with other blocks. The complexity grows quickly when you have nested AutoPipelineBlocks or use them as sub-blocks in larger pipelines.
+
+Let's make another `AutoPipelineBlocks` - this one only contains one block, and it does not include `None` in its `block_trigger_inputs` (which corresponds to the default block to run when none of the trigger inputs are provided). This means this block will be skipped if the trigger input (`ip_adapter_image`) is not provided at runtime.
+
+```py
+from diffusers.modular_pipelines import SequentialPipelineBlocks, InsertableDict
+inputs = [InputParam(name="ip_adapter_image")]
+block_fn = lambda x, y: print("running the ip-adapter workflow")
+block_ipa_cls = make_block(inputs=inputs, block_fn=block_fn, description="I'm a IP-adapter workflow!")
+
+class AutoIPAdapter(AutoPipelineBlocks):
+    block_classes = [block_ipa_cls]
+    block_names = ["ip-adapter"]
+    block_trigger_inputs = ["ip_adapter_image"]
+    @property
+    def description(self):
+        return "Run IP Adapter step if `ip_adapter_image` is provided."
+```
+
+Now let's combine these 2 auto blocks together into a `SequentialPipelineBlocks`:
+
+```py
+auto_ipa_blocks = AutoIPAdapter()
+blocks_dict = InsertableDict()
+blocks_dict["ip-adapter"] = auto_ipa_blocks
+blocks_dict["image-generation"] = auto_blocks
+all_blocks = SequentialPipelineBlocks.from_blocks_dict(blocks_dict)
+pipeline = all_blocks.init_pipeline()
+```
+
+Let's take a look: now things get more confusing. In this particular example, you could still try to explain the conditional logic in the `description` field here - there are only 4 possible execution paths so it's doable. However, since this is a `SequentialPipelineBlocks` that could contain many more blocks, the complexity can quickly get out of hand as the number of blocks increases.
+
+```py
+>>> all_blocks
+SequentialPipelineBlocks(
+  Class: ModularPipelineBlocks
+
+  ====================================================================================================
+  This pipeline contains blocks that are selected at runtime based on inputs.
+  Trigger Inputs: ['image', 'mask', 'ip_adapter_image']
+  Use `get_execution_blocks()` with input names to see selected blocks (e.g. `get_execution_blocks('image')`).
+  ====================================================================================================
+
+
+  Description: 
+
+
+  Sub-Blocks:
+    [0] ip-adapter (AutoIPAdapter)
+       Description: Run IP Adapter step if `ip_adapter_image` is provided.
+                   
+
+    [1] image-generation (AutoImageBlocks)
+       Description: Pipeline generates images given different types of conditions!
+                   This is an auto pipeline block that works for text2img, img2img and inpainting tasks.
+                    - inpaint workflow is run when `mask` is provided.
+                    - img2img workflow is run when `image` is provided (but only when `mask` is not provided).
+                    - text2img workflow is run when neither `image` nor `mask` is provided.
+                   
+
+)
+
+```
+
+This is when the `get_execution_blocks()` method comes in handy - it basically extracts a `SequentialPipelineBlocks` that only contains the blocks that are actually run based on your inputs.
+
+Let's try some examples:
+
+`mask`: we expect it to skip the first ip-adapter since `ip_adapter_image` is not provided, and then run the inpaint for the second block.
+
+```py
+>>> all_blocks.get_execution_blocks('mask')
+SequentialPipelineBlocks(
+  Class: ModularPipelineBlocks
+
+  Description: 
+
+
+  Sub-Blocks:
+    [0] image-generation (TestBlock)
+       Description: I'm a inpaint workflow!
+
+)
+```
+
+Let's also actually run the pipeline to confirm:
+
+```py
+>>> _ = pipeline(mask="mask")
+skipping auto block: AutoIPAdapter
+running the inpaint workflow
+```
+
+Try a few more:
+
+```py
+print(f"inputs: ip_adapter_image:")
+blocks_select = all_blocks.get_execution_blocks('ip_adapter_image')
+print(f"expected_execution_blocks: {blocks_select}")
+print(f"actual execution blocks:")
+_ = pipeline(ip_adapter_image="ip_adapter_image", prompt="prompt")
+# expect to see ip-adapter + text2img
+
+print(f"inputs: image:")
+blocks_select = all_blocks.get_execution_blocks('image')
+print(f"expected_execution_blocks: {blocks_select}")
+print(f"actual execution blocks:")
+_ = pipeline(image="image", prompt="prompt")
+# expect to see img2img
+
+print(f"inputs: prompt:")
+blocks_select = all_blocks.get_execution_blocks('prompt')
+print(f"expected_execution_blocks: {blocks_select}")
+print(f"actual execution blocks:")
+_ = pipeline(prompt="prompt")
+# expect to see text2img (prompt is not a trigger input so fallback to default)
+
+print(f"inputs: mask + ip_adapter_image:")
+blocks_select = all_blocks.get_execution_blocks('mask','ip_adapter_image')
+print(f"expected_execution_blocks: {blocks_select}")
+print(f"actual execution blocks:")
+_ = pipeline(mask="mask", ip_adapter_image="ip_adapter_image")
+# expect to see ip-adapter + inpaint
+```
+
+In summary, `AutoPipelineBlocks` is a good tool for packaging multiple workflows into a single, convenient interface and it can greatly simplify the user experience. However, always provide clear descriptions explaining the conditional logic, test individual pipelines first before combining them, and use `get_execution_blocks()` to understand runtime behavior in complex compositions.

+# Components Manager
+
+<Tip warning={true}>
+
+🧪 **Experimental Feature**: This is an experimental feature we are actively developing. The API may be subject to breaking changes.
+
+</Tip>
+
+The Components Manager is a central model registry and management system in diffusers. It lets you add models then reuse them across multiple pipelines and workflows. It tracks all models in one place with useful metadata such as model size, device placement and loaded adapters (LoRA, IP-Adapter). It has mechanisms in place to prevent duplicate model instances, enables memory-efficient sharing. Most significantly, it offers offloading that works across pipelines — unlike regular DiffusionPipeline offloading (i.e. `enable_model_cpu_offload` and `enable_sequential_cpu_offload`) which is limited to one pipeline with predefined sequences, the Components Manager automatically manages your device memory across all your models and workflows. 
+
+
+## Basic Operations
+
+Let's start with the most basic operations. First, create a Components Manager:
+
+```py
+from diffusers import ComponentsManager
+comp = ComponentsManager()
+```
+
+Use the `add(name, component)` method to register a component. It returns a unique ID that combines the component name with the object's unique identifier (using Python's `id()` function):
+
+```py
+from diffusers import AutoModel
+text_encoder = AutoModel.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder")
+# Returns component_id like 'text_encoder_139917733042864'
+component_id = comp.add("text_encoder", text_encoder)
+```
+
+You can view all registered components and their metadata:
+
+```py
+>>> comp
+Components:
+===============================================================================================================================================
+Models:
+-----------------------------------------------------------------------------------------------------------------------------------------------
+Name_ID                      | Class                     | Device: act(exec)    | Dtype           | Size (GB)  | Load ID         | Collection
+-----------------------------------------------------------------------------------------------------------------------------------------------
+text_encoder_139917733042864 | CLIPTextModel             | cpu                  | torch.float32   | 0.46       | N/A             | N/A
+-----------------------------------------------------------------------------------------------------------------------------------------------
+
+Additional Component Info:
+==================================================
+```
+
+And remove components using their unique ID:
+
+```py
+comp.remove("text_encoder_139917733042864")
+```
+
+## Duplicate Detection
+
+The Components Manager automatically detects and prevents duplicate model instances to save memory and avoid confusion. Let's walk through how this works in practice.
+
+When you try to add the same object twice, the manager will warn you and return the existing ID:
+
+```py
+>>> comp.add("text_encoder", text_encoder)
+'text_encoder_139917733042864'
+>>> comp.add("text_encoder", text_encoder)
+ComponentsManager: component 'text_encoder' already exists as 'text_encoder_139917733042864'
+'text_encoder_139917733042864'
+```
+
+Even if you add the same object under a different name, it will still be detected as a duplicate:
+
+```py
+>>> comp.add("clip", text_encoder)
+ComponentsManager: adding component 'clip' as 'clip_139917733042864', but it is duplicate of 'text_encoder_139917733042864'
+To remove a duplicate, call `components_manager.remove('<component_id>')`.
+'clip_139917733042864'
+```
+
+However, there's a more subtle case where duplicate detection becomes tricky. When you load the same model into different objects, the manager can't detect duplicates unless you use `ComponentSpec`. For example:
+
+```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'
+```
+
+This creates a problem - you now have two copies of the same model consuming double the memory:
+
+```py
+>>> comp
+Components:
+===============================================================================================================================================
+Models:
+-----------------------------------------------------------------------------------------------------------------------------------------------
+Name_ID                      | Class                     | Device: act(exec)    | Dtype           | Size (GB)  | Load ID         | Collection
+-----------------------------------------------------------------------------------------------------------------------------------------------
+text_encoder_139917733042864 | CLIPTextModel             | cpu                  | torch.float32   | 0.46       | N/A             | N/A
+clip_139917733042864         | CLIPTextModel             | cpu                  | torch.float32   | 0.46       | N/A             | N/A
+text_encoder_139917732983664 | CLIPTextModel             | cpu                  | torch.float32   | 0.46       | N/A             | N/A
+-----------------------------------------------------------------------------------------------------------------------------------------------
+
+Additional Component Info:
+==================================================
+```
+
+We recommend using `ComponentSpec` to load your models. Models loaded with `ComponentSpec` get tagged with a unique ID that encodes their loading parameters, allowing the Components Manager to detect 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 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())
+```
+
+Now the manager detects the duplicate and warns you:
+
+```out
+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'
+```
+
+Both models now show the same `load_id`, making it clear they're the same model:
+
+```py
+>>> comp
+Components:
+======================================================================================================================================================================================================
+Models:
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
+Name_ID                                 | Class                     | Device: act(exec)    | Dtype           | Size (GB)  | Load ID                                                         | Collection
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
+text_encoder_139918506246832            | CLIPTextModel             | cpu                  | torch.float32   | 0.46       | stabilityai/stable-diffusion-xl-base-1.0|text_encoder|null|null | N/A
+text_encoder_duplicated_139917580682672 | CLIPTextModel             | cpu                  | torch.float32   | 0.46       | stabilityai/stable-diffusion-xl-base-1.0|text_encoder|null|null | N/A
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
+
+Additional Component Info:
+==================================================
+```
+
+## Collections
+
+Collections are labels you can assign to components for better organization and management. You add a component under a collection by passing the `collection=` parameter when you add the component to the manager, i.e. `add(name, component, collection=...)`. Within each collection, only one component per name is allowed - if you add a second component with the same name, the first one is automatically removed.
+
+Here's how collections work in practice:
+
+```py
+comp = ComponentsManager()
+# Create ComponentSpec for the first UNet (SDXL base)
+spec = ComponentSpec(name="unet", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="unet", type_hint=AutoModel)
+# Create ComponentSpec for a different UNet (Juggernaut-XL)
+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")
+```
+
+The manager automatically removes the old UNet and adds the new one:
+
+```out
+ComponentsManager: removing existing unet from collection 'sdxl': unet_139917723891888
+'unet_139917723893136'
+```
+
+Only one UNet remains in the collection:
+
+```py
+>>> comp
+Components:

+
+For example, in node-based systems, you can mark all models loaded from one node with the same collection label, automatically replace models when user loads new checkpoints under same name, batch delete all models in a collection when a node is removed.
+
+## Retrieving Components
+
+The Components Manager provides several methods to retrieve registered components.
+
+The `get_one()` method returns a single component and supports pattern matching for the `name` parameter. You can use:
+- exact matches like `comp.get_one(name="unet")`
+- wildcards like `comp.get_one(name="unet*")` for components starting with "unet"
+- exclusion patterns like `comp.get_one(name="!unet")` to exclude components named "unet"
+- OR patterns like `comp.get_one(name="unet|vae")` to match either "unet" OR "vae". 
+
+Optionally, You can add collection and load_id as filters e.g. `comp.get_one(name="unet", collection="sdxl")`. If multiple components match, `get_one()` throws an error.
+
+Another useful method is `get_components_by_names()`, which takes a list of names and returns a dictionary mapping names to components. This is particularly helpful with modular pipelines since they provide lists of required component names, and the returned dictionary can be directly passed to `pipeline.update_components()`.
+
+```py
+# Get components by name list
+component_dict = comp.get_components_by_names(names=["text_encoder", "unet", "vae"])
+# Returns: {"text_encoder": component1, "unet": component2, "vae": component3}
+```
+
+## Using Components Manager with Modular Pipelines
+
+The Components Manager integrates seamlessly with Modular Pipelines. All you need to do is pass a Components Manager instance to `from_pretrained()` or `init_pipeline()` with an optional `collection` parameter:
+
+```py
+from diffusers import ModularPipeline, ComponentsManager
+comp = ComponentsManager()
+pipe = ModularPipeline.from_pretrained("YiYiXu/modular-demo-auto", components_manager=comp, collection="test1")
+```
+
+By default, modular pipelines don't load components immediately, so both the pipeline and Components Manager start empty:
+
+```py
+>>> comp
+Components:
+==================================================
+No components registered.
+==================================================
+```
+
+When you load components on the pipeline, they are automatically registered in the Components Manager:
+
+```py
+>>> pipe.load_components(names="unet")
+>>> comp
+Components:
+==============================================================================================================================================================
+Models:
+--------------------------------------------------------------------------------------------------------------------------------------------------------------
+Name_ID              | Class                     | Device: act(exec)    | Dtype           | Size (GB)  | Load ID                                | Collection
+--------------------------------------------------------------------------------------------------------------------------------------------------------------
+unet_139917726686304 | UNet2DConditionModel      | cpu                  | torch.float32   | 9.56       | SG161222/RealVisXL_V4.0|unet|null|null | test1
+--------------------------------------------------------------------------------------------------------------------------------------------------------------
+
+Additional Component Info:
+==================================================
+```
+
+Now let's load all default components and then create a second pipeline that reuses all components from the first one. We pass the same Components Manager to the second pipeline but with a different collection:
+
+```py
+# Load all default components 
+>>> pipe.load_default_components()
+
+# Create a second pipeline using the same Components Manager but with a different collection
+>>> pipe2 = ModularPipeline.from_pretrained("YiYiXu/modular-demo-auto", components_manager=comp, collection="test2")
+```
+
+As mentioned earlier, `ModularPipeline` has a property `null_component_names` that returns a list of component names it needs to load. We can conveniently use this list with the `get_components_by_names` method on the Components Manager:
+
+```py
+# Get the list of components that pipe2 needs to load
+>>> pipe2.null_component_names 
+['text_encoder', 'text_encoder_2', 'tokenizer', 'tokenizer_2', 'image_encoder', 'unet', 'vae', 'scheduler', 'controlnet']
+
+# Retrieve all required components from the Components Manager
+>>> comp_dict = comp.get_components_by_names(names=pipe2.null_component_names)
+
+# Update the pipeline with the retrieved components
+>>> pipe2.update_components(**comp_dict)
+```
+
+The warnings that follow are expected and indicate that the Components Manager is correctly identifying that these components already exist and will be reused rather than creating duplicates:
+
+```out
+ComponentsManager: component 'text_encoder' already exists as 'text_encoder_139917586016400'
+ComponentsManager: component 'text_encoder_2' already exists as 'text_encoder_2_139917699973424'
+ComponentsManager: component 'tokenizer' already exists as 'tokenizer_139917580599504'
+ComponentsManager: component 'tokenizer_2' already exists as 'tokenizer_2_139915763443904'
+ComponentsManager: component 'image_encoder' already exists as 'image_encoder_139917722468304'
+ComponentsManager: component 'unet' already exists as 'unet_139917580609632'
+ComponentsManager: component 'vae' already exists as 'vae_139917722459040'
+ComponentsManager: component 'scheduler' already exists as 'scheduler_139916266559408'
+ComponentsManager: component 'controlnet' already exists as 'controlnet_139917722454432'
+```
+
+
+The pipeline is now fully loaded:
+
+```py
+# null_component_names return empty list, meaning everything are loaded
+>>> pipe2.null_component_names
+[]
+```
+
+No new components were added to the Components Manager - we're reusing everything. All models are now associated with both `test1` and `test2` collections, showing that these components are shared across multiple pipelines:

+## Automatic Memory Management
+
+The Components Manager provides a global offloading strategy across all models, regardless of which pipeline is using them:
+
+```py
+comp.enable_auto_cpu_offload(device="cuda")
+```
+
+When enabled, all models start on CPU. The manager moves models to the device right before they're used and moves other models back to CPU when GPU memory runs low. You can set your own rules for which models to offload first. This works smoothly as you add or remove components. Once it's on, you don't need to worry about device placement - you can focus on your workflow.
+
+
+
+## Practical Example: Building Modular Workflows with Component Reuse
+
+Now that we've covered the basics of the Components Manager, let's walk through a practical example that shows how to build workflows in a modular setting and use the Components Manager to reuse components across multiple pipelines. This example demonstrates the true power of Modular Diffusers by working with multiple pipelines that can share components. 
+
+In this example, we'll generate latents from a text-to-image pipeline, then refine them with an image-to-image pipeline.
+
+Let's create a modular text-to-image workflow by separating it into three workflows: `text_blocks` for encoding prompts, `t2i_blocks` for generating latents, and `decoder_blocks` for creating final images.
+
+```py
+import torch
+from diffusers.modular_pipelines import SequentialPipelineBlocks
+from diffusers.modular_pipelines.stable_diffusion_xl import ALL_BLOCKS
+
+# Create modular blocks and separate text encoding and decoding steps
+t2i_blocks = SequentialPipelineBlocks.from_blocks_dict(ALL_BLOCKS["text2img"])
+text_blocks = t2i_blocks.sub_blocks.pop("text_encoder")
+decoder_blocks = t2i_blocks.sub_blocks.pop("decode")
+```
+
+Now we will convert them into runnalbe pipelines and set up the Components Manager with auto offloading and organize components under a "t2i" collection
+
+Since we now have 3 different workflows that share components, we create a separate pipeline that serves as a dedicated loader to load all the components, register them to the component manager, and then reuse them across different workflows.
+
+```py
+from diffusers import ComponentsManager, ModularPipeline
+
+# Set up Components Manager with auto offloading
+components = ComponentsManager()
+components.enable_auto_cpu_offload(device="cuda")
+
+# Create a new pipeline to load the components
+t2i_repo = "YiYiXu/modular-demo-auto"
+t2i_loader_pipe = ModularPipeline.from_pretrained(t2i_repo, components_manager=components, collection="t2i")
+
+# convert the 3 blocks into pipelines and attach the same components manager to all 3
+text_node = text_blocks.init_pipeline(t2i_repo, components_manager=components)
+decoder_node = decoder_blocks.init_pipeline(t2i_repo, components_manager=components)
+t2i_pipe = t2i_blocks.init_pipeline(t2i_repo, components_manager=components)
+```
+
+Load all components into the loader pipeline, they should all be automatically registered to Components Manager under the "t2i" collection:
+
+```py
+# Load all components (including IP-Adapter and ControlNet for later use)
+t2i_loader_pipe.load_default_components(torch_dtype=torch.float16)
+```
+
+Now distribute the loaded components to each pipeline:
+
+```py
+# Get VAE for decoder (using get_one since there's only one)
+vae = components.get_one(load_id="SG161222/RealVisXL_V4.0|vae|null|null")
+decoder_node.update_components(vae=vae)
+
+# Get text components for text node (using get_components_by_names for multiple components)
+text_components = components.get_components_by_names(text_node.null_component_names)
+text_node.update_components(**text_components)
+
+# Get remaining components for t2i pipeline
+t2i_components = components.get_components_by_names(t2i_pipe.null_component_names)
+t2i_pipe.update_components(**t2i_components)
+```
+
+Now we can generate images using our modular workflow:
+
+```py
+# Generate text embeddings
+prompt = "an astronaut"
+text_embeddings = text_node(prompt=prompt, output=["prompt_embeds","negative_prompt_embeds", "pooled_prompt_embeds", "negative_pooled_prompt_embeds"])
+
+# Generate latents and decode to image
+generator = torch.Generator(device="cuda").manual_seed(0)
+latents_t2i = t2i_pipe(**text_embeddings, num_inference_steps=25, generator=generator, output="latents")
+image = decoder_node(latents=latents_t2i, output="images")[0]
+image.save("modular_part2_t2i.png")
+```
+
+Let's add a LoRA:
+
+```py
+# Load LoRA weights 
+>>> t2i_loader_pipe.load_lora_weights("CiroN2022/toy-face", weight_name="toy_face_sdxl.safetensors", adapter_name="toy_face")
+>>> components
+Components:
+============================================================================================================================================================
+...
+Additional Component Info:
+==================================================
+
+unet:
+  Adapters: ['toy_face']
+```
+
+You can see that the Components Manager tracks adapters metadata for all models it manages, and in our case, only Unet has lora loaded. This means we can reuse existing text embeddings. 
+
+```py
+# Generate with LoRA (reusing existing text embeddings)
+generator = torch.Generator(device="cuda").manual_seed(0)
+latents_lora = t2i_pipe(**text_embeddings, num_inference_steps=25, generator=generator, output="latents")
+image = decoder_node(latents=latents_lora, output="images")[0]
+image.save("modular_part2_lora.png")
+```
+
+
+Now let's create a refiner pipeline that reuses components from our text-to-image workflow:
+
+```py
+# Create refiner blocks (removing image_encoder and decode since we work with latents)
+refiner_blocks = SequentialPipelineBlocks.from_blocks_dict(ALL_BLOCKS["img2img"])
+refiner_blocks.sub_blocks.pop("image_encoder")
+refiner_blocks.sub_blocks.pop("decode")
+
+# Create refiner pipeline with different repo and collection,
+# Attach the same component manager to it
+refiner_repo = "YiYiXu/modular_refiner"
+refiner_pipe = refiner_blocks.init_pipeline(refiner_repo, components_manager=components, collection="refiner")
+```
+
+We pass the **same Components Manager** (`components`) to the refiner pipeline, but with a **different collection** (`"refiner"`). This allows the refiner to access and reuse components from the "t2i" collection while organizing its own components (like the refiner UNet) under the "refiner" collection. 
+
+```py
+# Load only the refiner UNet (different from t2i UNet)
+refiner_pipe.load_components(names="unet", torch_dtype=torch.float16)
+
+# Reuse components from t2i pipeline using pattern matching
+reuse_components = components.search_components("text_encoder_2|scheduler|vae|tokenizer_2")
+refiner_pipe.update_components(**reuse_components)
+```
+
+When we reuse components from the "t2i" collection, they automatically get added to the "refiner" collection as well. You can verify this by checking the Components Manager - you'll see components like `vae`, `scheduler`, etc. listed under both collections, indicating they're shared between workflows.
+
+Now we can refine any of our generated latents:
+
+```py
+# Refine all our different latents
+refined_latents = refiner_pipe(image_latents=latents_t2i, prompt=prompt, num_inference_steps=10, output="latents")
+refined_image = decoder_node(latents=refined_latents, output="images")[0]
+refined_image.save("modular_part2_t2i_refine_out.png")
+
+refined_latents = refiner_pipe(image_latents=latents_lora, prompt=prompt, num_inference_steps=10, output="latents")
+refined_image = decoder_node(latents=refined_latents, output="images")[0]
+refined_image.save("modular_part2_lora_refine_out.png")
+```
+
+
+Here are the results from our modular pipeline examples.

+# End-to-End Developer Guide: Building with Modular Diffusers
+
+<Tip warning={true}>
+
+🧪 **Experimental Feature**: Modular Diffusers is an experimental feature we are actively developing. The API may be subject to breaking changes.
+
+</Tip>
+
+
+In this tutorial we will walk through the process of adding a new pipeline to the modular framework using differential diffusion as our example. We'll cover the complete workflow from implementation to deployment: implementing the new pipeline, ensuring compatibility with existing tools, sharing the code on Hugging Face Hub, and deploying it as a UI node. 
+
+We'll also demonstrate the 4-step framework process we use for implementing new basic pipelines in the modular system.
+
+1. **Start with an existing pipeline as a base**
+   - Identify which existing pipeline is most similar to the one you want to implement
+   - Determine what part of the pipeline needs modification
+
+2. **Build a working pipeline structure first**
+   - Assemble the complete pipeline structure
+   - Use existing blocks wherever possible
+   - For new blocks, create placeholders (e.g. you can copy from similar blocks and change the name) without implementing custom logic just yet
+
+3. **Set up an example**
+   - Create a simple inference script with expected inputs/outputs
+
+4. **Implement your custom logic and test incrementally**
+   - Add the custom logics the blocks you want to change
+   - Test incrementally, and inspect pipeline states and debug as needed
+
+Let's see how this works with the Differential Diffusion example.
+
+
+## Differential Diffusion Pipeline
+
+### Start with an existing pipeline
+
+Differential diffusion (https://differential-diffusion.github.io/) is an image-to-image workflow, so it makes sense for us to start with the preset of pipeline blocks used to build img2img pipeline (`IMAGE2IMAGE_BLOCKS`) and see how we can build this new pipeline with them. 
+
+```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)
+... ])
+```
+
+Note that "denoise" (`StableDiffusionXLDenoiseStep`) is a `LoopSequentialPipelineBlocks` that contains 3 loop blocks (more on LoopSequentialPipelineBlocks [here](https://huggingface.co/docs/diffusers/modular_diffusers/write_own_pipeline_block#loopsequentialpipelineblocks))
+
+```py
+>>> denoise_blocks = IMAGE2IMAGE_BLOCKS["denoise"]()
+>>> print(denoise_blocks)
+```

+```
+
+Let's compare standard image-to-image and differential diffusion! The key difference in algorithm is that standard image-to-image diffusion applies uniform noise across all pixels based on a single `strength` parameter, but differential diffusion uses a change map where each pixel value determines when that region starts denoising. Regions with lower values get "frozen" earlier by replacing them with noised original latents, preserving more of the original image.
+
+Therefore, the key differences when it comes to pipeline implementation would be:
+1. The `prepare_latents` step (which prepares the change map and pre-computes noised latents for all timesteps) 
+2. The `denoise` step (which selectively applies denoising based on the change map)
+3. Since differential diffusion doesn't use the `strength` parameter, we'll use the text-to-image `set_timesteps` step instead of the image-to-image version
+
+To implement differntial diffusion, we can reuse most blocks from image-to-image and text-to-image workflows, only modifying the `prepare_latents` step and the first part of the `denoise` step (i.e. `before_denoiser (StableDiffusionXLLoopBeforeDenoiser)`). 
+
+Here's a flowchart showing the pipeline structure and the changes we need to make:

+
+
+### Build a Working Pipeline Structure
+
+ok now we've identified the blocks to modify, let's build the pipeline skeleton first - at this stage, our goal is to get the pipeline struture working end-to-end (even though it's just doing the img2img behavior). I would simply create placeholder blocks by copying from existing ones:
+
+```py
+>>> # Copy existing blocks as placeholders
+>>> class SDXLDiffDiffPrepareLatentsStep(PipelineBlock):
+...     """Copied from StableDiffusionXLImg2ImgPrepareLatentsStep - will modify later"""
+...     # ... same implementation as StableDiffusionXLImg2ImgPrepareLatentsStep
+... 
+>>> class SDXLDiffDiffLoopBeforeDenoiser(PipelineBlock):
+...     """Copied from StableDiffusionXLLoopBeforeDenoiser - will modify later"""
+...     # ... same implementation as StableDiffusionXLLoopBeforeDenoiser
+```
+
+`SDXLDiffDiffLoopBeforeDenoiser` is the be part of the denoise loop we need to change. Let's use it to assemble a `SDXLDiffDiffDenoiseStep`.
+
+```py
+>>> class SDXLDiffDiffDenoiseStep(StableDiffusionXLDenoiseLoopWrapper):
+...     block_classes = [SDXLDiffDiffLoopBeforeDenoiser, StableDiffusionXLLoopDenoiser, StableDiffusionXLLoopAfterDenoiser]
+...     block_names = ["before_denoiser", "denoiser", "after_denoiser"]
+```
+
+Now we can put together our differential diffusion pipeline.
+
+```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)
+>>> # At this point, the pipeline works exactly like img2img since our blocks are just copies
+```
+
+### Set up an example
+
+ok, so now our blocks should be able to compile without an error, we can move on to the next step. Let's setup a simple example so we can run the pipeline as we build it. diff-diff use same model checkpoints as SDXL so we can fetch the models from a regular SDXL repo.
+
+```py
+>>> dd_pipeline = dd_blocks.init_pipeline("YiYiXu/modular-demo-auto", collection="diffdiff")
+>>> dd_pipeline.load_default_componenets(torch_dtype=torch.float16)
+>>> dd_pipeline.to("cuda")
+```
+
+We will use this example script:
+
+```py
+>>> 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"
+>>> 
+>>> image = dd_pipeline(
+...     prompt=prompt,
+...     negative_prompt=negative_prompt,
+...     num_inference_steps=25,
+...     diffdiff_map=mask,
+...     image=image,
+...     output="images"
+... )[0]
+>>> 
+>>> image.save("diffdiff_out.png")
+```
+
+If you run the script right now, you will get a complaint about unexpected input `diffdiff_map`. 
+and you would get the same result as the original img2img pipeline.
+
+### implement your custom logic and test incrementally
+
+Let's modify the pipeline so that we can get expected result with this example script.
+
+We'll start with the `prepare_latents` step. The main changes are:
+- Requires a new user input `diffdiff_map`
+- Requires new component `mask_processor` to process the `diffdiff_map`
+- Requires new intermediate inputs: 
+  - Need `timestep` instead of `latent_timestep` to precompute all the latents
+  - Need `num_inference_steps` to create the `diffdiff_masks`
+- create a new output `diffdiff_masks` and `original_latents`
+
+<Tip>
+
+💡  use `print(dd_pipeline.doc)` to check compiled inputs and outputs of the built piepline. 
+
+e.g. after we added `diffdiff_map` as an input in this step, we can run `print(dd_pipeline.doc)` to verify that it shows up in the docstring as a user input. 
+
+</Tip>
+
+Once we make sure all the variables we need are available in the block state, we can implement the diff-diff logic inside `__call__`. We created 2 new variables: the change map `diffdiff_mask` and the pre-computed noised latents for all timesteps `original_latents`.
+
+<Tip>
+
+💡  Implement incrementally! Run the example script as you go, and insert `print(state)` and `print(block_state)` everywhere inside the `__call__` method to inspect the intermediate results. This helps you understand what's going on and what each line you just added does.
+
+</Tip>
+
+Here are the key changes we made to implement differential diffusion:
+
+**1. Modified `prepare_latents` step:**
+```diff

++       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
+```
+
+**2. Modified `before_denoiser` step:**
+```diff
+class SDXLDiffDiffLoopBeforeDenoiser(PipelineBlock):
+    @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[Tuple[str, Any]]:
++       return [
++           InputParam("denoising_start"),
++       ]
+
+    @property
+    def intermediate_inputs(self) -> List[str]:
+        return [
+            InputParam("latents", required=True, type_hint=torch.Tensor),
++           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 ...
+```
+
+That's all there is to it! We've just created a simple sequential pipeline by mix-and-match some existing and new pipeline blocks.
+
+Now we use the process we've prepred in step2 to build the pipeline and inspect it.

+
+## Adding IP-adapter
+
+We provide an auto IP-adapter block that you can plug-and-play into your modular workflow. It's an `AutoPipelineBlocks`, so it will only run when the user passes an IP adapter image. In this tutorial, we'll focus on how to package it into your differential diffusion workflow. To learn more about `AutoPipelineBlocks`, see [here](./auto_pipeline_blocks.md)
+
+We talked about how to add IP-adapter into your workflow in the [Modular Pipeline Guide](./modular_pipeline.md). Let's just go ahead to create the IP-adapter block.
+
+```py
+>>> from diffusers.modular_pipelines.stable_diffusion_xl.encoders import StableDiffusionXLAutoIPAdapterStep
+>>> ip_adapter_block = StableDiffusionXLAutoIPAdapterStep()
+```
+
+We can directly add the ip-adapter block instance to the `diffdiff_blocks` that we created before. The `sub_blocks` attribute is a `InsertableDict`, so we're able to insert the it at specific position (index `0` here).
+
+```py
+>>> dd_blocks.sub_blocks.insert("ip_adapter", ip_adapter_block, 0)
+```
+
+Take a look at the new diff-diff pipeline with ip-adapter! 
+
+```py
+>>> print(dd_blocks)
+```
+
+The pipeline now lists ip-adapter as its first block, and tells you that it will run only if `ip_adapter_image` is provided. It also includes the two new components from ip-adpater: `image_encoder` and `feature_extractor`
+
+```out

+```
+
+Let's test it out. We used an orange image to condition the generation via ip-addapter and we can see a slight orange color and texture in the final output.

+
+## Working with ControlNets
+
+What about controlnet? Can differential diffusion work with controlnet? The key differences between a regular pipeline and a ControlNet pipeline are:
+1. A ControlNet input step that prepares the control condition
+2. Inside the denoising loop, a modified denoiser step where the control image is first processed through ControlNet, then control information is injected into the UNet
+
+From looking at the code workflow: differential diffusion only modifies the "before denoiser" step, while ControlNet operates within the "denoiser" itself. Since they intervene at different points in the pipeline, they should work together without conflicts.
+
+Intuitively, these two techniques are orthogonal and should combine naturally: differential diffusion controls how much the inference process can deviate from the original in each region, while ControlNet controls in what direction that change occurs.
+
+With this understanding, let's assemble the diffdiff-controlnet loop by combining the diffdiff before-denoiser step and controlnet denoiser step.
+
+```py
+>>> class SDXLDiffDiffControlNetDenoiseStep(StableDiffusionXLDenoiseLoopWrapper):
+...     block_classes = [SDXLDiffDiffLoopBeforeDenoiser, StableDiffusionXLControlNetLoopDenoiser, StableDiffusionXLDenoiseLoopAfterDenoiser]
+...     block_names = ["before_denoiser", "denoiser", "after_denoiser"]
+>>> 
+>>> controlnet_denoise_block = SDXLDiffDiffControlNetDenoiseStep()
+>>> # print(controlnet_denoise)
+```
+
+We provide a auto controlnet input block that you can directly put into your workflow to proceess the `control_image`: similar to auto ip-adapter block, this step will only run if `control_image` input is passed from user. It work with both controlnet and controlnet union.
+
+
+```py
+>>> from diffusers.modular_pipelines.stable_diffusion_xl.modular_blocks import StableDiffusionXLAutoControlNetInputStep
+>>> control_input_block = StableDiffusionXLAutoControlNetInputStep()
+>>> print(control_input_block)
+```
+
+```out

+      This is an auto pipeline block that works for both controlnet and controlnet_union.
+       (it should be called right before the denoise step) - `StableDiffusionXLControlNetUnionInputStep` is called to prepare the controlnet input when `control_mode` and `control_image` are provided.
+       - `StableDiffusionXLControlNetInputStep` is called to prepare the controlnet input when `control_image` is provided. - if neither `control_mode` nor `control_image` is provided, step will be skipped.
+
+
+  Components:
+      controlnet (`ControlNetUnionModel`)
+      control_image_processor (`VaeImageProcessor`)
+
+  Sub-Blocks:
+    • controlnet_union [trigger: control_mode] (StableDiffusionXLControlNetUnionInputStep)
+       Description: step that prepares inputs for the ControlNetUnion model
+
+    • controlnet [trigger: control_image] (StableDiffusionXLControlNetInputStep)
+       Description: step that prepare inputs for controlnet
+
+)
+
+```
+
+Let's assemble the blocks and run an example using controlnet + differential diffusion. We used a tomato as `control_image`, so you can see that in the output, the right half that transformed into a pear had a tomato-like shape.
+
+```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]
+```
+
+Optionally, We can combine `SDXLDiffDiffControlNetDenoiseStep` and `SDXLDiffDiffDenoiseStep` into a `AutoPipelineBlocks` so that same workflow can work with or without controlnet. 
+
+
+```py
+>>> class SDXLDiffDiffAutoDenoiseStep(AutoPipelineBlocks):
+...     block_classes = [SDXLDiffDiffControlNetDenoiseStep, SDXLDiffDiffDenoiseStep]
+...     block_names = ["controlnet_denoise", "denoise"]
+...     block_trigger_inputs = ["controlnet_cond", None]
+```
+
+`SDXLDiffDiffAutoDenoiseStep` will run the ControlNet denoise step if `control_image` input is provided, otherwise it will run the regular denoise step.
+
+<Tip>
+
+ Note that it's perfectly fine not to use `AutoPipelineBlocks`. In fact, we recommend only using `AutoPipelineBlocks` to package your workflow at the end once you've verified all your pipelines work as expected.
+
+</Tip>
+
+Now you can create the differential diffusion preset that works with ip-adapter & controlnet.
+
+```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)
+>>> 
+>>> print(DIFFDIFF_AUTO_BLOCKS)
+```
+
+to use
+
+```py
+>>> dd_auto_blocks = SequentialPipelineBlocks.from_blocks_dict(DIFFDIFF_AUTO_BLOCKS)
+>>> dd_pipeline = dd_auto_blocks.init_pipeline(...)
+```
+## Creating a Modular Repo
+
+You can easily share your differential diffusion workflow on the Hub by creating a modular repo. This is one created using the code we just wrote together: https://huggingface.co/YiYiXu/modular-diffdiff
+
+To create a Modular Repo and share on hub, you just need to run `save_pretrained()` along with the `push_to_hub=True` flag. Note that if your pipeline contains custom block, you need to manually upload the code to the hub. But we are working on a command line tool to help you upload it very easily.
+
+```py
+dd_pipeline.save_pretrained("YiYiXu/test_modular_doc", push_to_hub=True)
+```
+
+With a modular repo, it is very easy for the community to use the workflow you just created! Here is an example to use the differential-diffusion pipeline we just created and shared.
+
+```py
+>>> from diffusers.modular_pipelines import ModularPipeline, ComponentsManager
+>>> import torch
+>>> from diffusers.utils import load_image
+>>> 
+>>> repo_id = "YiYiXu/modular-diffdiff-0704"
+>>> 
+>>> components = ComponentsManager()
+>>> 
+>>> diffdiff_pipeline = ModularPipeline.from_pretrained(repo_id, trust_remote_code=True, components_manager=components, collection="diffdiff")
+>>> diffdiff_pipeline.load_default_components(torch_dtype=torch.float16)
+>>> components.enable_auto_cpu_offload()
+```
+
+see more usage example on model card.

+# LoopSequentialPipelineBlocks
+
+<Tip warning={true}>
+
+🧪 **Experimental Feature**: Modular Diffusers is an experimental feature we are actively developing. The API may be subject to breaking changes.
+
+</Tip>
+
+`LoopSequentialPipelineBlocks` is a subclass of `ModularPipelineBlocks`. It is a multi-block that composes other blocks together in a loop, creating iterative workflows where blocks run multiple times with evolving state. It's particularly useful for denoising loops requiring repeated execution of the same blocks.
+
+<Tip>
+
+Other types of multi-blocks include [SequentialPipelineBlocks](./sequential_pipeline_blocks.md) (for linear workflows) and [AutoPipelineBlocks](./auto_pipeline_blocks.md) (for conditional block selection). For information on creating individual blocks, see the [PipelineBlock guide](./pipeline_block.md).
+
+Additionally, like all `ModularPipelineBlocks`, `LoopSequentialPipelineBlocks` are definitions/specifications, not runnable pipelines. You need to convert them into a `ModularPipeline` to actually execute them. For information on creating and running pipelines, see the [Modular Pipeline guide](modular_pipeline.md).
+
+</Tip>
+
+You could create a loop using `PipelineBlock` like this:
+
+```python
+class DenoiseLoop(PipelineBlock):
+    def __call__(self, components, state):
+        block_state = self.get_block_state(state)
+        for t in range(block_state.num_inference_steps):
+            # ... loop logic here
+            pass
+        self.set_block_state(state, block_state)
+        return components, state
+```
+
+But in this tutorial, we will focus on how to use `LoopSequentialPipelineBlocks` to create a "composable" denoising loop where you can add or remove blocks within the loop or reuse the same loop structure with different block combinations.
+
+It involves two parts: a **loop wrapper** and **loop blocks**
+
+* The **loop wrapper** (`LoopSequentialPipelineBlocks`) defines the loop structure, e.g. it defines the iteration variables, and loop configurations such as progress bar.
+
+* The **loop blocks** are basically standard pipeline blocks you add to the loop wrapper.
+  - they run sequentially for each iteration of the loop
+  - they receive the current iteration index as an additional parameter
+  - they share the same block_state throughout the entire loop
+
+Unlike regular `SequentialPipelineBlocks` where each block gets its own state, loop blocks share a single state that persists and evolves across iterations.
+
+We will build a simple loop block to demonstrate these concepts. Creating a loop block involves three steps:
+1. defining the loop wrapper class
+2. creating the loop blocks
+3. adding the loop blocks to the loop wrapper class to create the loop wrapper instance
+
+**Step 1: Define the Loop Wrapper**
+
+To create a `LoopSequentialPipelineBlocks` class, you need to define:
+
+* `loop_inputs`: User input variables (equivalent to `PipelineBlock.inputs`)
+* `loop_intermediate_inputs`: Intermediate variables needed from the mutable pipeline state (equivalent to `PipelineBlock.intermediates_inputs`)
+* `loop_intermediate_outputs`: New intermediate variables this block will add to the mutable pipeline state (equivalent to `PipelineBlock.intermediates_outputs`)
+* `__call__` method: Defines the loop structure and iteration logic
+
+Here is an example of a loop wrapper:
+
+```py
+import torch
+from diffusers.modular_pipelines import LoopSequentialPipelineBlocks, PipelineBlock, 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
+```
+
+**Step 2: Create Loop Blocks**
+
+Loop blocks are standard `PipelineBlock`s, but their `__call__` method works differently:
+* It receives the iteration variable (e.g., `i`) passed by the loop wrapper
+* It works directly with `block_state` instead of pipeline state
+* No need to call `self.get_block_state()` or `self.set_block_state()`
+
+```py
+class LoopBlock(PipelineBlock):
+    # this is used to identify the model family, we won't worry about it in this example
+    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
+```
+
+**Step 3: Combine Everything**
+
+Finally, assemble your loop by adding the block(s) to the wrapper:
+
+```py
+loop = LoopWrapper.from_blocks_dict({"block1": LoopBlock})
+```
+
+Now you've created a loop with one step:
+
+```py
+>>> loop
+LoopWrapper(
+  Class: LoopSequentialPipelineBlocks
+
+  Description: I'm a loop!!
+
+  Sub-Blocks:
+    [0] block1 (LoopBlock)
+       Description: I'm a block used inside the `LoopWrapper` class
+
+)
+```
+
+It has two inputs: `x` (used at each step within the loop) and `num_steps` used to define the loop.
+
+```py
+>>> print(loop.doc)
+class LoopWrapper
+
+  I'm a loop!!
+
+  Inputs:
+
+      x (`None`, *optional*):
+
+      num_steps (`None`, *optional*):
+
+  Outputs:
+
+      x (`None`):
+```
+
+**Running the Loop:**
+
+```py
+# run the loop
+loop_pipeline = loop.init_pipeline()
+x = loop_pipeline(num_steps=10, x=0, output="x")
+assert x == 10
+```
+
+**Adding Multiple Blocks:**
+
+We can add multiple blocks to run within each iteration. Let's run the loop block twice within each iteration:
+
+```py
+loop = LoopWrapper.from_blocks_dict({"block1": LoopBlock(), "block2": LoopBlock})
+loop_pipeline = loop.init_pipeline()
+x = loop_pipeline(num_steps=10, x=0, output="x")
+assert x == 20  # Each iteration runs 2 blocks, so 10 iterations * 2 = 20
+```
+
+**Key Differences from SequentialPipelineBlocks:**
+
+The main difference is that loop blocks share the same `block_state` across all iterations, allowing values to accumulate and evolve throughout the loop. Loop blocks could receive additional arguments (like the current iteration index) depending on the loop wrapper's implementation, since the wrapper defines how loop blocks are called. You can easily add, remove, or reorder blocks within the loop without changing the loop logic itself.
+
+The officially supported denoising loops in Modular Diffusers are implemented using `LoopSequentialPipelineBlocks`. You can explore the actual implementation to see how these concepts work in practice:
+
+```py
+from diffusers.modular_pipelines.stable_diffusion_xl.denoise import StableDiffusionXLDenoiseStep
+StableDiffusionXLDenoiseStep()
+```

+# PipelineState and BlockState
+
+<Tip warning={true}>
+
+🧪 **Experimental Feature**: Modular Diffusers is an experimental feature we are actively developing. The API may be subject to breaking changes.
+
+</Tip>
+
+In Modular Diffusers, `PipelineState` and `BlockState` are the core data structures that enable blocks to communicate and share data. The concept is fundamental to understand how blocks interact with each other and the pipeline system.
+
+In the modular diffusers system, `PipelineState` acts as the global state container that all pipeline blocks operate on. It maintains the complete runtime state of the pipeline and provides a structured way for blocks to read from and write to shared data.
+
+A `PipelineState` consists of two distinct states:
+
+- **The immutable state** (i.e. the `inputs` dict) contains a copy of values provided by users. Once a value is added to the immutable state, it cannot be changed. Blocks can read from the immutable state but cannot write to it.
+
+- **The mutable state** (i.e. the `intermediates` dict) contains variables that are passed between blocks and can be modified by them.
+
+Here's an example of what a `PipelineState` looks like:
+
+```py
+PipelineState(
+  inputs={
+    'prompt': 'a cat'
+    'guidance_scale': 7.0
+    'num_inference_steps': 25
+  },
+  intermediates={
+    'prompt_embeds': Tensor(dtype=torch.float32, shape=torch.Size([1, 1, 1, 1]))
+    'negative_prompt_embeds': None
+  },
+)
+```
+
+Each pipeline blocks define what parts of that state they can read from and write to through their `inputs`, `intermediate_inputs`, and `intermediate_outputs` properties. At run time, they gets a local view (`BlockState`) of the relevant variables it needs from `PipelineState`, performs its operations, and then updates `PipelineState` with any changes.
+
+For example, if a block defines an input `image`, inside the block's `__call__` method, the `BlockState` would contain:
+
+```py
+BlockState(
+    image: <PIL.Image.Image image mode=RGB size=512x512 at 0x7F3ECC494640>
+)
+```
+
+You can access the variables directly as attributes: `block_state.image`.
+
+We will explore more on how blocks interact with pipeline state through their `inputs`, `intermediate_inputs`, and `intermediate_outputs` properties, see the [PipelineBlock guide](./pipeline_block.md).

+# Getting Started with Modular Diffusers
+
+<Tip warning={true}>
+
+🧪 **Experimental Feature**: Modular Diffusers is an experimental feature we are actively developing. The API may be subject to breaking changes.
+
+</Tip>
+
+With Modular Diffusers, we introduce a unified pipeline system that simplifies how you work with diffusion models. Instead of creating separate pipelines for each task, Modular Diffusers lets you:
+
+**Write Only What's New**: You won't need to write an entire pipeline from scratch every time you have a new use case. You can create pipeline blocks just for your new workflow's unique aspects and reuse existing blocks for existing functionalities. 
+
+**Assemble Like LEGO®**: You can mix and match between blocks in flexible ways. This allows you to write dedicated blocks unique to specific workflows, and then assemble different blocks into a pipeline that can be used more conveniently for multiple workflows.

+# PipelineBlock
+
+<Tip warning={true}>
+
+🧪 **Experimental Feature**: Modular Diffusers is an experimental feature we are actively developing. The API may be subject to breaking changes.
+
+</Tip>
+
+In Modular Diffusers, you build your workflow using `ModularPipelineBlocks`. We support 4 different types of blocks: `PipelineBlock`, `SequentialPipelineBlocks`, `LoopSequentialPipelineBlocks`, and `AutoPipelineBlocks`. Among them, `PipelineBlock` is the most fundamental building block of the whole system - it's like a brick in a Lego system. These blocks are designed to easily connect with each other, allowing for modular construction of creative and potentially very complex workflows.
+
+<Tip>
+
+**Important**: `PipelineBlock`s are definitions/specifications, not runnable pipelines. They define what a block should do and what data it needs, but you need to convert them into a `ModularPipeline` to actually execute them. For information on creating and running pipelines, see the [Modular Pipeline guide](./modular_pipeline.md).
+
+</Tip>
+
+In this tutorial, we will focus on how to write a basic `PipelineBlock` and how it interacts with the pipeline state.
+
+## PipelineState
+
+Before we dive into creating `PipelineBlock`s, make sure you have a basic understanding of `PipelineState`. It acts as the global state container that all blocks operate on - each block gets a local view (`BlockState`) of the relevant variables it needs from `PipelineState`, performs its operations, and then updates `PipelineState` with any changes. See the [PipelineState and BlockState guide](./modular_diffusers_states.md) for more details.
+
+## Define a `PipelineBlock`
+
+To write a `PipelineBlock` class, you need to define a few properties that determine how your block interacts with the pipeline state. Understanding these properties is crucial - they define what data your block can access and what it can produce.
+
+The three main properties you need to define are:
+- `inputs`: Immutable values from the user that cannot be modified
+- `intermediate_inputs`: Mutable values from previous blocks that can be read and modified  
+- `intermediate_outputs`: New values your block creates for subsequent blocks and user access
+
+Let's explore each one and understand how they work with the pipeline state.
+
+**Inputs: Immutable User Values**
+
+Inputs are variables your block needs from the immutable pipeline state - these are user-provided values that cannot be modified by any block. You define them using `InputParam`:
+
+```py
+user_inputs = [
+    InputParam(name="image", type_hint="PIL.Image", description="raw input image to process")
+]
+```
+
+When you list something as an input, you're saying "I need this value directly from the end user, and I will talk to them directly, telling them what I need in the 'description' field. They will provide it and it will come to me unchanged."
+
+This is especially useful for raw values that serve as the "source of truth" in your workflow. For example, with a raw image, many workflows require preprocessing steps like resizing that a previous block might have performed. But in many cases, you also want the raw PIL image. In some inpainting workflows, you need the original image to overlay with the generated result for better control and consistency.
+
+**Intermediate Inputs: Mutable Values from Previous Blocks, or Users**
+
+Intermediate inputs are variables your block needs from the mutable pipeline state - these are values that can be read and modified. They're typically created by previous blocks, but could also be directly provided by the user if not the case:
+
+```py
+user_intermediate_inputs = [
+    InputParam(name="processed_image", type_hint="torch.Tensor", description="image that has been preprocessed and normalized"),
+]
+```
+
+When you list something as an intermediate input, you're saying "I need this value, but I want to work with a different block that has already created it. I already know for sure that I can get it from this other block, but it's okay if other developers want use something different."
+
+**Intermediate Outputs: New Values for Subsequent Blocks and User Access**
+
+Intermediate outputs are new variables your block creates and adds to the mutable pipeline state. They serve two purposes:
+
+1. **For subsequent blocks**: They can be used as intermediate inputs by other blocks in the pipeline
+2. **For users**: They become available as final outputs that users can access when running the pipeline
+
+```py
+user_intermediate_outputs = [
+    OutputParam(name="image_latents", description="latents representing the image")
+]
+```
+
+Intermediate inputs and intermediate outputs work together like Lego studs and anti-studs - they're the connection points that make blocks modular. When one block produces an intermediate output, it becomes available as an intermediate input for subsequent blocks. This is where the "modular" nature of the system really shines - blocks can be connected and reconnected in different ways as long as their inputs and outputs match.
+
+Additionally, all intermediate outputs are accessible to users when they run the pipeline, typically you would only need the final images, but they are also able to access intermediate results like latents, embeddings, or other processing steps.
+
+**The `__call__` Method Structure**
+
+Your `PipelineBlock`'s `__call__` method should follow this structure:
+
+```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
+    # You can 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
+```
+
+The `block_state` object contains all the variables you defined in `inputs` and `intermediate_inputs`, making them easily accessible for your computation.
+
+**Components and Configs**
+
+You can define the components and pipeline-level configs your block needs using `ComponentSpec` and `ConfigSpec`:
+
+```py
+from diffusers import ComponentSpec, ConfigSpec
+
+# Define components your block needs
+expected_components = [
+    ComponentSpec(name="unet", type_hint=UNet2DConditionModel),
+    ComponentSpec(name="scheduler", type_hint=EulerDiscreteScheduler)
+]
+
+# Define pipeline-level configs
+expected_config = [
+    ConfigSpec("force_zeros_for_empty_prompt", True)
+]
+```
+
+**Components**: In the `ComponentSpec`, you must provide a `name` and ideally a `type_hint`. You can also specify a `default_creation_method` to indicate whether the component should be loaded from a pretrained model or created with default configurations. The actual loading details (`repo`, `subfolder`, `variant` and `revision` fields) are typically specified when creating the pipeline, as we covered in the [Modular Pipeline Guide](./modular_pipeline.md).
+
+**Configs**: Pipeline-level settings that control behavior across all blocks.
+
+When you convert your blocks into a pipeline using `blocks.init_pipeline()`, the pipeline collects all component requirements from the blocks and fetches the loading specs from the modular repository. The components are then made available to your block as the first argument of the `__call__` method. You can access any component you need using dot notation:
+
+```py
+def __call__(self, components, state):
+    # Access components using dot notation
+    unet = components.unet
+    vae = components.vae
+    scheduler = components.scheduler
+```
+
+That's all you need to define in order to create a `PipelineBlock`. There is no hidden complexity. In fact we are going to create a helper function that take exactly these variables as input and return a pipeline block. We will use this helper function through out the tutorial to create test blocks
+
+Note that for `__call__` method, the only part you should implement differently is the part between `self.get_block_state()` and `self.set_block_state()`, which can be abstracted into a simple function that takes `block_state` and returns the updated state. Our helper function accepts a `block_fn` that does exactly that.
+
+**Helper Function**
+
+```py
+from diffusers.modular_pipelines import PipelineBlock, InputParam, OutputParam
+import torch
+
+def make_block(inputs=[], intermediate_inputs=[], intermediate_outputs=[], block_fn=None, description=None):
+    class TestBlock(PipelineBlock):
+        model_name = "test"
+        
+        @property
+        def inputs(self):
+            return inputs
+            
+        @property
+        def intermediate_inputs(self):

+            return description if description is not None else ""
+            
+        def __call__(self, components, state):
+            block_state = self.get_block_state(state)
+            if block_fn is not None:
+                block_state = block_fn(block_state, state)
+            self.set_block_state(state, block_state)
+            return components, state
+    
+    return TestBlock
+```
+
+## Example: Creating a Simple Pipeline Block
+
+Let's create a simple block to see how these definitions interact with the pipeline state. To better understand what's happening, we'll print out the states before and after updates to inspect them:
+
+```py
+inputs = [
+    InputParam(name="image", type_hint="PIL.Image", description="raw input image to process")
+]
+
+intermediate_inputs = [InputParam(name="batch_size", type_hint=int)]
+
+intermediate_outputs = [
+    OutputParam(name="image_latents", description="latents representing the image")
+]
+
+def image_encoder_block_fn(block_state, pipeline_state):
+    print(f"pipeline_state (before update): {pipeline_state}")
+    print(f"block_state (before update): {block_state}")
+    
+    # Simulate processing the image
+    block_state.image = torch.randn(1, 3, 512, 512)
+    block_state.batch_size = block_state.batch_size * 2
+    block_state.processed_image = [torch.randn(1, 3, 512, 512)] * block_state.batch_size
+    block_state.image_latents = torch.randn(1, 4, 64, 64)
+    
+    print(f"block_state (after update): {block_state}")
+    return block_state
+
+# Create a block with our definitions
+image_encoder_block_cls = make_block(
+    inputs=inputs, 
+    intermediate_inputs=intermediate_inputs,
+    intermediate_outputs=intermediate_outputs, 
+    block_fn=image_encoder_block_fn,
+    description="Encode raw image into its latent presentation"
+)
+image_encoder_block = image_encoder_block_cls()
+pipe = image_encoder_block.init_pipeline()
+```
+
+Let's check the pipeline's docstring to see what inputs it expects:
+```py
+>>> print(pipe.doc)
+class TestBlock
+
+  Encode raw image into its latent presentation
+
+  Inputs:
+
+      image (`PIL.Image`, *optional*):
+          raw input image to process
+
+      batch_size (`int`, *optional*):
+
+  Outputs:
+
+      image_latents (`None`):
+          latents representing the image
+```
+
+Notice that `batch_size` appears as an input even though we defined it as an intermediate input. This happens because no previous block provided it, so the pipeline makes it available as a user input. However, unlike regular inputs, this value goes directly into the mutable intermediate state.
+
+Now let's run the pipeline:
+
+```py
+from diffusers.utils import load_image
+
+image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/image_of_squirrel_painting.png")
+state = pipe(image=image, batch_size=2)
+print(f"pipeline_state (after update): {state}")
+```
+```out
+pipeline_state (before update): PipelineState(
+  inputs={
+    image: <PIL.Image.Image image mode=RGB size=512x512 at 0x7F3ECC494550>
+  },
+  intermediates={
+    batch_size: 2
+  },
+)
+block_state (before update): BlockState(
+    image: <PIL.Image.Image image mode=RGB size=512x512 at 0x7F3ECC494640>
+    batch_size: 2
+)
+
+block_state (after update): BlockState(
+    image: Tensor(dtype=torch.float32, shape=torch.Size([1, 3, 512, 512]))
+    batch_size: 4
+    processed_image: List[4] of Tensors with shapes [torch.Size([1, 3, 512, 512]), torch.Size([1, 3, 512, 512]), torch.Size([1, 3, 512, 512]), torch.Size([1, 3, 512, 512])]
+    image_latents: Tensor(dtype=torch.float32, shape=torch.Size([1, 4, 64, 64]))
+)
+pipeline_state (after update): PipelineState(
+  inputs={
+    image: <PIL.Image.Image image mode=RGB size=512x512 at 0x7F3ECC494550>
+  },
+  intermediates={
+    batch_size: 4
+    image_latents: Tensor(dtype=torch.float32, shape=torch.Size([1, 4, 64, 64]))
+  },
+)
+```
+
+**Key Observations:**
+
+1. **Before the update**: `image` (the input) goes to the immutable inputs dict, while `batch_size` (the intermediate_input) goes to the mutable intermediates dict, and both are available in `block_state`.
+
+2. **After the update**:
+   - **`image` (inputs)** changed in `block_state` but not in `pipeline_state` - this change is local to the block only. 
+   - **`batch_size (intermediate_inputs)`** was updated in both `block_state` and `pipeline_state` - this change affects subsequent blocks (we didn't need to declare it as an intermediate output since it was already in the intermediates dict)
+   - **`image_latents (intermediate_outputs)`** was added to `pipeline_state` because it was declared as an intermediate output
+   - **`processed_image`** was not added to `pipeline_state` because it wasn't declared as an intermediate output

+# SequentialPipelineBlocks
+
+<Tip warning={true}>
+
+🧪 **Experimental Feature**: Modular Diffusers is an experimental feature we are actively developing. The API may be subject to breaking changes.
+
+</Tip>
+
+`SequentialPipelineBlocks` is a subclass of `ModularPipelineBlocks`. Unlike `PipelineBlock`, it is a multi-block that composes other blocks together in sequence, creating modular workflows where data flows from one block to the next. It's one of the most common ways to build complex pipelines by combining simpler building blocks.
+
+<Tip>
+
+Other types of multi-blocks include [AutoPipelineBlocks](auto_pipeline_blocks.md) (for conditional block selection) and [LoopSequentialPipelineBlocks](loop_sequential_pipeline_blocks.md) (for iterative workflows). For information on creating individual blocks, see the [PipelineBlock guide](pipeline_block.md).
+
+Additionally, like all `ModularPipelineBlocks`, `SequentialPipelineBlocks` are definitions/specifications, not runnable pipelines. You need to convert them into a `ModularPipeline` to actually execute them. For information on creating and running pipelines, see the [Modular Pipeline guide](modular_pipeline.md).
+
+</Tip>
+
+In this tutorial, we will focus on how to create `SequentialPipelineBlocks` and how blocks connect and work together.
+
+The key insight is that blocks connect through their intermediate inputs and outputs - the "studs and anti-studs" we discussed in the [PipelineBlock guide](pipeline_block.md). When one block produces an intermediate output, it becomes available as an intermediate input for subsequent blocks.
+
+Let's explore this through an example. We will use the same helper function from the PipelineBlock guide to create blocks.
+
+```py
+from diffusers.modular_pipelines import PipelineBlock, InputParam, OutputParam
+import torch
+
+def make_block(inputs=[], intermediate_inputs=[], intermediate_outputs=[], block_fn=None, description=None):
+    class TestBlock(PipelineBlock):
+        model_name = "test"
+        
+        @property
+        def inputs(self):
+            return inputs
+            
+        @property
+        def intermediate_inputs(self):
+            return intermediate_inputs
+            
+        @property
+        def intermediate_outputs(self):
+            return intermediate_outputs
+            
+        @property
+        def description(self):
+            return description if description is not None else ""
+            
+        def __call__(self, components, state):
+            block_state = self.get_block_state(state)
+            if block_fn is not None:
+                block_state = block_fn(block_state, state)
+            self.set_block_state(state, block_state)
+            return components, state
+    
+    return TestBlock
+```
+
+Let's create a block that produces `batch_size`, which we'll call "input_block":
+
+```py
+def input_block_fn(block_state, pipeline_state):
+    
+    batch_size = len(block_state.prompt)
+    block_state.batch_size = batch_size * block_state.num_images_per_prompt
+    
+    return block_state
+
+input_block_cls = make_block(
+    inputs=[
+        InputParam(name="prompt", type_hint=list, description="list of text prompts"),
+        InputParam(name="num_images_per_prompt", type_hint=int, description="number of images per prompt")
+    ],
+    intermediate_outputs=[
+        OutputParam(name="batch_size", description="calculated batch size")
+    ],
+    block_fn=input_block_fn,
+    description="A block that determines batch_size based on the number of prompts and num_images_per_prompt argument."
+)
+input_block = input_block_cls()
+```
+
+Now let's create a second block that uses the `batch_size` from the first block:
+
+```py
+def image_encoder_block_fn(block_state, pipeline_state):
+    # Simulate processing the image
+    block_state.image = torch.randn(1, 3, 512, 512)
+    block_state.batch_size = block_state.batch_size * 2
+    block_state.image_latents = torch.randn(1, 4, 64, 64)
+    return block_state
+
+image_encoder_block_cls = make_block(
+    inputs=[
+        InputParam(name="image", type_hint="PIL.Image", description="raw input image to process")
+    ],
+    intermediate_inputs=[
+        InputParam(name="batch_size", type_hint=int)
+    ],
+    intermediate_outputs=[
+        OutputParam(name="image_latents", description="latents representing the image")
+    ],
+    block_fn=image_encoder_block_fn,
+    description="Encode raw image into its latent presentation"
+)
+image_encoder_block = image_encoder_block_cls()
+```
+
+Now let's connect these blocks to create a `SequentialPipelineBlocks`:
+
+```py
+from diffusers.modular_pipelines import SequentialPipelineBlocks, InsertableDict
+
+# Define a dict mapping block names to block instances
+blocks_dict = InsertableDict()
+blocks_dict["input"] = input_block
+blocks_dict["image_encoder"] = image_encoder_block
+
+# Create the SequentialPipelineBlocks
+blocks = SequentialPipelineBlocks.from_blocks_dict(blocks_dict)
+```
+
+Now you have a `SequentialPipelineBlocks` with 2 blocks:
+
+```py
+>>> blocks
+SequentialPipelineBlocks(
+  Class: ModularPipelineBlocks
+
+  Description: 
+
+
+  Sub-Blocks:
+    [0] input (TestBlock)
+       Description: A block that determines batch_size based on the number of prompts and num_images_per_prompt argument.
+
+    [1] image_encoder (TestBlock)
+       Description: Encode raw image into its latent presentation
+
+)
+```
+
+When you inspect `blocks.doc`, you can see that `batch_size` is not listed as an input. The pipeline automatically detects that the `input_block` can produce `batch_size` for the `image_encoder_block`, so it doesn't ask the user to provide it.
+
+```py
+>>> print(blocks.doc)
+class SequentialPipelineBlocks
+
+  Inputs:
+
+      prompt (`None`, *optional*):
+
+      num_images_per_prompt (`None`, *optional*):
+
+      image (`PIL.Image`, *optional*):
+          raw input image to process
+
+  Outputs:
+
+      batch_size (`None`):
+
+      image_latents (`None`):
+          latents representing the image
+```
+
+At runtime, you have data flow like this:
+
+![Data Flow Diagram](https://huggingface.co/datasets/YiYiXu/testing-images/resolve/main/modular_quicktour/Editor%20_%20Mermaid%20Chart-2025-06-30-092631.png)
+
+**How SequentialPipelineBlocks Works:**
+
+1. Blocks are executed in the order they're registered in the `blocks_dict`
+2. Outputs from one block become available as intermediate inputs to all subsequent blocks
+3. The pipeline automatically figures out which values need to be provided by the user and which will be generated by previous blocks
+4. Each block maintains its own behavior and operates through its defined interface, while collectively these interfaces determine what the entire pipeline accepts and produces
+
+What happens within each block follows the same pattern we described earlier: each block gets its own `block_state` with the relevant inputs and intermediate inputs, performs its computation, and updates the pipeline state with its intermediate outputs.

 Compilation is slow the first time, but once compiled, it is significantly faster. Try to only use the compiled pipeline on the same type of inference operations. Calling the compiled pipeline on a different image size retriggers compilation which is slow and inefficient.
 
+### Dynamic shape compilation
+
+> [!TIP]
+> Make sure to always use the nightly version of PyTorch for better support.
+
+`torch.compile` keeps track of input shapes and conditions, and if these are different, it recompiles the model. For example, if a model is compiled on a 1024x1024 resolution image and used on an image with a different resolution, it triggers recompilation.
+
+To avoid recompilation, add `dynamic=True` to try and generate a more dynamic kernel to avoid recompilation when conditions change.
+
+```diff
++ torch.fx.experimental._config.use_duck_shape = False
++ pipeline.unet = torch.compile(
+    pipeline.unet, fullgraph=True, dynamic=True
+)
+```
+
+Specifying `use_duck_shape=False` instructs the compiler if it should use the same symbolic variable to represent input sizes that are the same. For more details, check out this [comment](https://github.com/huggingface/diffusers/pull/11327#discussion_r2047659790).
+
+Not all models may benefit from dynamic compilation out of the box and may require changes. Refer to this [PR](https://github.com/huggingface/diffusers/pull/11297/) that improved the [`AuraFlowPipeline`] implementation to benefit from dynamic compilation.
+
+Feel free to open an issue if dynamic compilation doesn't work as expected for a Diffusers model.

 ### Regional compilation
 
-[Regional compilation](https://docs.pytorch.org/tutorials/recipes/regional_compilation.html) reduces the cold start compilation time by only compiling a specific repeated region (or block) of the model instead of the entire model. The compiler reuses the cached and compiled code for the other blocks.
+[Regional compilation](https://docs.pytorch.org/tutorials/recipes/regional_compilation.html) trims cold-start latency by only compiling the *small and frequently-repeated block(s)* of a model - typically a transformer layer - and enables reusing compiled artifacts for every subsequent occurrence.
+For many diffusion architectures, this delivers the same runtime speedups as full-graph compilation and reduces compile time by 8–10x.
 
-[Accelerate](https://huggingface.co/docs/accelerate/index) provides the [compile_regions](https://github.com/huggingface/accelerate/blob/273799c85d849a1954a4f2e65767216eb37fa089/src/accelerate/utils/other.py#L78) method for automatically compiling the repeated blocks of a `nn.Module` sequentially. The rest of the model is compiled separately.
+Use the [`~ModelMixin.compile_repeated_blocks`] method, a helper that wraps `torch.compile`, on any component such as the transformer model as shown below.
+
+```py
+# pip install -U diffusers
+import torch
+from diffusers import StableDiffusionXLPipeline
+
+pipeline = StableDiffusionXLPipeline.from_pretrained(
+    "stabilityai/stable-diffusion-xl-base-1.0",
+    torch_dtype=torch.float16,
+).to("cuda")
+
+# compile only the repeated transformer layers inside the UNet
+pipeline.unet.compile_repeated_blocks(fullgraph=True)
+```
+
+To enable regional compilation for a new model, add a `_repeated_blocks` attribute to a model class containing the class names (as strings) of the blocks you want to compile.
+
+```py
+class MyUNet(ModelMixin):
+    _repeated_blocks = ("Transformer2DModel",)  # ← compiled by default

 Optimizing models often involves trade-offs between [inference speed](./fp16) and [memory-usage](./memory).

+# 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.

 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*.

+
+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.

+# Batch inference
+
+Batch inference processes multiple prompts at a time to increase throughput. It is more efficient because processing multiple prompts at once maximizes GPU usage versus processing a single prompt and underutilizing the GPU.
+
+The downside is increased latency because you must wait for the entire batch to complete, and more GPU memory is required for large batches.

+
+Use a list comprehension to iterate over the batch size specified in `range()` to create a unique `Generator` object for each image in the batch.
+
+Don't multiply the `Generator` by the batch size because that only creates one `Generator` object that is used sequentially for each image in the batch.
+
+```py
+generator = [torch.Generator(device="cuda").manual_seed(0)] * 3
+```
+
+Pass the `generator` to the pipeline.

+from diffusers import DiffusionPipeline
+

+    "stabilityai/stable-diffusion-xl-base-1.0",

-The inference pipeline supports and enables a wide range of techniques that are divided into two categories:
-
-* 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.

-Define four different `Generator`s and assign each `Generator` a seed (`0` to `3`). Then generate a batch of images and pick one to iterate on.

-> [!WARNING]
-> Use a list comprehension that iterates over the batch size specified in `range()` to create a unique `Generator` object for each image in the batch. If you multiply the `Generator` by the batch size integer, it only creates *one* `Generator` object that is used sequentially for each image in the batch.

-Let's improve the first image (you can choose any image you want) which corresponds to the `Generator` with seed `0`. Add some additional text to your prompt and then make sure you reuse the same `Generator` with seed `0`. All the generated images should resemble the first image.

+Use the `torch_dtype` argument in [`~ModelMixin.from_pretrained`] to specify the dtype to load a model in.

+```py
+from diffusers import AutoModel

+unet = AutoModel.from_pretrained(
+    "stabilityai/stable-diffusion-xl-base-1.0", subfolder="unet", torch_dtype=torch.float16

+
+You can also use the [torch.Tensor.to](https://docs.pytorch.org/docs/stable/generated/torch.Tensor.to.html) method to convert to the specified dtype on the fly. It converts *all* weights unlike the `torch_dtype` argument that respects the `_keep_in_fp32_modules`. This is important for models whose layers must remain in fp32 for numerical stability and best generation quality (see example [here](https://github.com/huggingface/diffusers/blob/f864a9a352fa4a220d860bfdd1782e3e5af96382/src/diffusers/models/transformers/transformer_wan.py#L374)).
