A Diffusion Transformer model for 3D video-like data from [ChronoEdit: Towards Temporal Reasoning for Image Editing and World Simulation](https://huggingface.co/papers/2510.04290) from NVIDIA and University of Toronto, by Jay Zhangjie Wu, Xuanchi Ren, Tianchang Shen, Tianshi Cao, Kai He, Yifan Lu, Ruiyuan Gao, Enze Xie, Shiyi Lan, Jose M. Alvarez, Jun Gao, Sanja Fidler, Zian Wang, Huan Ling.
> **TL;DR:** ChronoEdit reframes image editing as a video generation task, using input and edited images as start/end frames to leverage pretrained video models with temporal consistency. A temporal reasoning stage introduces reasoning tokens to ensure physically plausible edits and visualize the editing trajectory.
The model can be loaded with the following code snippet.

# SanaVideoTransformer3DModel
A Diffusion Transformer model for 3D data (video) from [SANA-Video: Efficient Video Generation with Block Linear Diffusion Transformer](https://huggingface.co/papers/2509.24695) from NVIDIA and MIT HAN Lab, by Junsong Chen, Yuyang Zhao, Jincheng Yu, Ruihang Chu, Junyu Chen, Shuai Yang, Xianbang Wang, Yicheng Pan, Daquan Zhou, Huan Ling, Haozhe Liu, Hongwei Yi, Hao Zhang, Muyang Li, Yukang Chen, Han Cai, Sanja Fidler, Ping Luo, Song Han, Enze Xie.
The abstract from the paper is:
*We introduce SANA-Video, a small diffusion model that can efficiently generate videos up to 720x1280 resolution and minute-length duration. SANA-Video synthesizes high-resolution, high-quality and long videos with strong text-video alignment at a remarkably fast speed, deployable on RTX 5090 GPU. Two core designs ensure our efficient, effective and long video generation: (1) Linear DiT: We leverage linear attention as the core operation, which is more efficient than vanilla attention given the large number of tokens processed in video generation. (2) Constant-Memory KV cache for Block Linear Attention: we design block-wise autoregressive approach for long video generation by employing a constant-memory state, derived from the cumulative properties of linear attention. This KV cache provides the Linear DiT with global context at a fixed memory cost, eliminating the need for a traditional KV cache and enabling efficient, minute-long video generation. In addition, we explore effective data filters and model training strategies, narrowing the training cost to 12 days on 64 H100 GPUs, which is only 1% of the cost of MovieGen. Given its low cost, SANA-Video achieves competitive performance compared to modern state-of-the-art small diffusion models (e.g., Wan 2.1-1.3B and SkyReel-V2-1.3B) while being 16x faster in measured latency. Moreover, SANA-Video can be deployed on RTX 5090 GPUs with NVFP4 precision, accelerating the inference speed of generating a 5-second 720p video from 71s to 29s (2.4x speedup). In summary, SANA-Video enables low-cost, high-quality video generation.*
The model can be loaded with the following code snippet.
```python
from diffusers import SanaVideoTransformer3DModel
import torch
transformer = SanaVideoTransformer3DModel.from_pretrained("Efficient-Large-Model/SANA-Video_2B_480p_diffusers", subfolder="transformer", torch_dtype=torch.bfloat16)

# Bria Fibo
Text-to-image models have mastered imagination - but not control. FIBO changes that.
FIBO is trained on structured JSON captions up to 1,000+ words and designed to understand and control different visual parameters such as lighting, composition, color, and camera settings, enabling precise and reproducible outputs.
With only 8 billion parameters, FIBO provides a new level of image quality, prompt adherence and proffesional control.
FIBO is trained exclusively on a structured prompt and will not work with freeform text prompts.
you can use the [FIBO-VLM-prompt-to-JSON](https://huggingface.co/briaai/FIBO-VLM-prompt-to-JSON) model or the [FIBO-gemini-prompt-to-JSON](https://huggingface.co/briaai/FIBO-gemini-prompt-to-JSON) to convert your freeform text prompt to a structured JSON prompt.
> [!NOTE]
> Avoid using freeform text prompts directly with FIBO because it does not produce the best results.
Refer to the Bria Fibo Hugging Face [page](https://huggingface.co/briaai/FIBO) to learn more.
## Usage
_As the model is gated, before using it with diffusers you first need to go to the [Bria Fibo Hugging Face page](https://huggingface.co/briaai/FIBO), fill in the form and accept the gate. Once you are in, you need to login so that your system knows youve accepted the gate._

# ChronoEdit
[ChronoEdit: Towards Temporal Reasoning for Image Editing and World Simulation](https://huggingface.co/papers/2510.04290) from NVIDIA and University of Toronto, by Jay Zhangjie Wu, Xuanchi Ren, Tianchang Shen, Tianshi Cao, Kai He, Yifan Lu, Ruiyuan Gao, Enze Xie, Shiyi Lan, Jose M. Alvarez, Jun Gao, Sanja Fidler, Zian Wang, Huan Ling.
> **TL;DR:** ChronoEdit reframes image editing as a video generation task, using input and edited images as start/end frames to leverage pretrained video models with temporal consistency. A temporal reasoning stage introduces reasoning tokens to ensure physically plausible edits and visualize the editing trajectory.
*Recent advances in large generative models have greatly enhanced both image editing and in-context image generation, yet a critical gap remains in ensuring physical consistency, where edited objects must remain coherent. This capability is especially vital for world simulation related tasks. In this paper, we present ChronoEdit, a framework that reframes image editing as a video generation problem. First, ChronoEdit treats the input and edited images as the first and last frames of a video, allowing it to leverage large pretrained video generative models that capture not only object appearance but also the implicit physics of motion and interaction through learned temporal consistency. Second, ChronoEdit introduces a temporal reasoning stage that explicitly performs editing at inference time. Under this setting, target frame is jointly denoised with reasoning tokens to imagine a plausible editing trajectory that constrains the solution space to physically viable transformations. The reasoning tokens are then dropped after a few steps to avoid the high computational cost of rendering a full video. To validate ChronoEdit, we introduce PBench-Edit, a new benchmark of image-prompt pairs for contexts that require physical consistency, and demonstrate that ChronoEdit surpasses state-of-the-art baselines in both visual fidelity and physical plausibility. Project page for code and models: [this https URL](https://research.nvidia.com/labs/toronto-ai/chronoedit).*
The ChronoEdit pipeline is developed by the ChronoEdit Team. The original code is available on [GitHub](https://github.com/nv-tlabs/ChronoEdit), and pretrained models can be found in the [nvidia/ChronoEdit](https://huggingface.co/collections/nvidia/chronoedit) collection on Hugging Face.

Flux.2 is the recent series of image generation models from Black Forest Labs, preceded by the [Flux.1](./flux.md) series. It is an entirely new model with a new architecture and pre-training done from scratch!
Original model checkpoints for Flux can be found [here](https://huggingface.co/black-forest-labs). Original inference code can be found [here](https://github.com/black-forest-labs/flux2).
> [!TIP]
> Flux2 can be quite expensive to run on consumer hardware devices. However, you can perform a suite of optimizations to run it faster and in a more memory-friendly manner. Check out [this section](https://huggingface.co/blog/sd3#memory-optimizations-for-sd3) for more details. Additionally, Flux can benefit from quantization for memory efficiency with a trade-off in inference latency. Refer to [this blog post](https://huggingface.co/blog/quanto-diffusers) to learn more.
>
> [Caching](../../optimization/cache) may also speed up inference by storing and reusing intermediate outputs.
## Caption upsampling
Flux.2 can potentially generate better better outputs with better prompts. We can "upsample"
an input prompt by setting the `caption_upsample_temperature` argument in the pipeline call arguments.
The [official implementation](https://github.com/black-forest-labs/flux2/blob/5a5d316b1b42f6b59a8c9194b77c8256be848432/src/flux2/text_encoder.py#L140) recommends this value to be 0.15.

# HunyuanVideo-1.5
HunyuanVideo-1.5 is a lightweight yet powerful video generation model that achieves state-of-the-art visual quality and motion coherence with only 8.3 billion parameters, enabling efficient inference on consumer-grade GPUs. This achievement is built upon several key components, including meticulous data curation, an advanced DiT architecture with selective and sliding tile attention (SSTA), enhanced bilingual understanding through glyph-aware text encoding, progressive pre-training and post-training, and an efficient video super-resolution network. Leveraging these designs, we developed a unified framework capable of high-quality text-to-video and image-to-video generation across multiple durations and resolutions. Extensive experiments demonstrate that this compact and proficient model establishes a new state-of-the-art among open-source models.
You can find all the original HunyuanVideo checkpoints under the [Tencent](https://huggingface.co/tencent) organization.

Refer to the [Attention backends](../../optimization/attention_backends) guide for more details about using a different backend.
```py
pipe.transformer.set_attention_backend("flash_hub") # or your preferred backend
```
- [`HunyuanVideo15Pipeline`] use guider and does not take `guidance_scale` parameter at runtime.
You can check the default guider configuration using `pipe.guider`:
```py
>>> pipe.guider
ClassifierFreeGuidance {
"_class_name": "ClassifierFreeGuidance",
"_diffusers_version": "0.36.0.dev0",
"enabled": true,
"guidance_rescale": 0.0,
"guidance_scale": 6.0,
"start": 0.0,
"stop": 1.0,
"use_original_formulation": false
}
State:
step: None
num_inference_steps: None
timestep: None
count_prepared: 0
enabled: True
num_conditions: 2
```
To update guider configuration, you can run `pipe.guider = pipe.guider.new(...)`
```py
pipe.guider = pipe.guider.new(guidance_scale=5.0)
```

# HunyuanImage2.1
HunyuanImage-2.1 is a 17B text-to-image model that is capable of generating 2K (2048 x 2048) resolution images
HunyuanImage-2.1 comes in the following variants:
| model type | model id |
|:----------:|:--------:|
| HunyuanImage-2.1 | [hunyuanvideo-community/HunyuanImage-2.1-Diffusers](https://huggingface.co/hunyuanvideo-community/HunyuanImage-2.1-Diffusers) |
| HunyuanImage-2.1-Distilled | [hunyuanvideo-community/HunyuanImage-2.1-Distilled-Diffusers](https://huggingface.co/hunyuanvideo-community/HunyuanImage-2.1-Distilled-Diffusers) |
| HunyuanImage-2.1-Refiner | [hunyuanvideo-community/HunyuanImage-2.1-Refiner-Diffusers](https://huggingface.co/hunyuanvideo-community/HunyuanImage-2.1-Refiner-Diffusers) |
> [!TIP]
> [Caching](../../optimization/cache) may also speed up inference by storing and reusing intermediate outputs.
## HunyuanImage-2.1
HunyuanImage-2.1 applies [Adaptive Projected Guidance (APG)](https://huggingface.co/papers/2410.02416) combined with Classifier-Free Guidance (CFG) in the denoising loop. `HunyuanImagePipeline` has a `guider` component (read more about [Guider](../modular_diffusers/guiders.md)) and does not take a `guidance_scale` parameter at runtime. To change guider-related parameters, e.g., `guidance_scale`, you can update the `guider` configuration instead.
```python
import torch
from diffusers import HunyuanImagePipeline
pipe = HunyuanImagePipeline.from_pretrained(
"hunyuanvideo-community/HunyuanImage-2.1-Diffusers",
torch_dtype=torch.bfloat16
)
pipe = pipe.to("cuda")
```
You can inspect the `guider` object:
```py
>>> pipe.guider
AdaptiveProjectedMixGuidance {
"_class_name": "AdaptiveProjectedMixGuidance",
"_diffusers_version": "0.36.0.dev0",
"adaptive_projected_guidance_momentum": -0.5,
"adaptive_projected_guidance_rescale": 10.0,
"adaptive_projected_guidance_scale": 10.0,
"adaptive_projected_guidance_start_step": 5,
"enabled": true,
"eta": 0.0,
"guidance_rescale": 0.0,
"guidance_scale": 3.5,
"start": 0.0,
"stop": 1.0,
"use_original_formulation": false
}
State:
step: None
num_inference_steps: None
timestep: None
count_prepared: 0
enabled: True
num_conditions: 2
momentum_buffer: None
is_apg_enabled: False
is_cfg_enabled: True
```
To update the guider with a different configuration, use the `new()` method. For example, to generate an image with `guidance_scale=5.0` while keeping all other default guidance parameters:
```py
import torch
from diffusers import HunyuanImagePipeline
pipe = HunyuanImagePipeline.from_pretrained(
"hunyuanvideo-community/HunyuanImage-2.1-Diffusers",
torch_dtype=torch.bfloat16
)
pipe = pipe.to("cuda")
# Update the guider configuration
pipe.guider = pipe.guider.new(guidance_scale=5.0)
prompt = (
"A cute, cartoon-style anthropomorphic penguin plush toy with fluffy fur, standing in a painting studio, "
"wearing a red knitted scarf and a red beret with the word 'Tencent' on it, holding a paintbrush with a "
"focused expression as it paints an oil painting of the Mona Lisa, rendered in a photorealistic photographic style."
)
image = pipe(
prompt=prompt,
num_inference_steps=50,
height=2048,
width=2048,
).images[0]
image.save("image.png")
```
## HunyuanImage-2.1-Distilled
use `distilled_guidance_scale` with the guidance-distilled checkpoint,
```py
import torch
from diffusers import HunyuanImagePipeline
pipe = HunyuanImagePipeline.from_pretrained("hunyuanvideo-community/HunyuanImage-2.1-Distilled-Diffusers", torch_dtype=torch.bfloat16)
pipe = pipe.to("cuda")
prompt = (
"A cute, cartoon-style anthropomorphic penguin plush toy with fluffy fur, standing in a painting studio, "
"wearing a red knitted scarf and a red beret with the word 'Tencent' on it, holding a paintbrush with a "
"focused expression as it paints an oil painting of the Mona Lisa, rendered in a photorealistic photographic style."
)
out = pipe(
prompt,
num_inference_steps=8,
distilled_guidance_scale=3.25,
height=2048,
width=2048,
generator=generator,
).images[0]
```

- LTX-Video 0.9.8 distilled model is similar to the 0.9.7 variant. It is guidance and timestep-distilled, and similar inference code can be used as above. An improvement of this version is that it supports generating very long videos. Additionally, it supports using tone mapping to improve the quality of the generated video using the `tone_map_compression_ratio` parameter. The default value of `0.6` is recommended.

# Ovis-Image
![concepts](https://github.com/AIDC-AI/Ovis-Image/blob/main/docs/imgs/ovis_image_case.png)
Ovis-Image is a 7B text-to-image model specifically optimized for high-quality text rendering, designed to operate efficiently under stringent computational constraints.
[Ovis-Image Technical Report](https://arxiv.org/abs/2511.22982) from Alibaba Group, by Guo-Hua Wang, Liangfu Cao, Tianyu Cui, Minghao Fu, Xiaohao Chen, Pengxin Zhan, Jianshan Zhao, Lan Li, Bowen Fu, Jiaqi Liu, Qing-Guo Chen.
The abstract from the paper is:
*We introduce Ovis-Image, a 7B text-to-image model specifically optimized for high-quality text rendering, designed to operate efficiently under stringent computational constraints. Built upon our previous Ovis-U1 framework, Ovis-Image integrates a diffusion-based visual decoder with the stronger Ovis 2.5 multimodal backbone, leveraging a text-centric training pipeline that combines large-scale pre-training with carefully tailored post-training refinements. Despite its compact architecture, Ovis-Image achieves text rendering performance on par with significantly larger open models such as Qwen-Image and approaches closed-source systems like Seedream and GPT4o. Crucially, the model remains deployable on a single high-end GPU with moderate memory, narrowing the gap between frontier-level text rendering and practical deployment. Our results indicate that combining a strong multimodal backbone with a carefully designed, text-focused training recipe is sufficient to achieve reliable bilingual text rendering without resorting to oversized or proprietary models.*
**Highlights**:
* **Strong text rendering at a compact 7B scale**: Ovis-Image is a 7B text-to-image model that delivers text rendering quality comparable to much larger 20B-class systems such as Qwen-Image and competitive with leading closed-source models like GPT4o in text-centric scenarios, while remaining small enough to run on widely accessible hardware.
* **High fidelity on text-heavy, layout-sensitive prompts**: The model excels on prompts that demand tight alignment between linguistic content and rendered typography (e.g., posters, banners, logos, UI mockups, infographics), producing legible, correctly spelled, and semantically consistent text across diverse fonts, sizes, and aspect ratios without compromising overall visual quality.
* **Efficiency and deployability**: With its 7B parameter budget and streamlined architecture, Ovis-Image fits on a single high-end GPU with moderate memory, supports low-latency interactive use, and scales to batch production serving, bringing nearfrontier text rendering to applications where tens-of-billionsparameter models are impractical.

# PRX
PRX generates high-quality images from text using a simplified MMDIT architecture where text tokens don't update through transformer blocks. It employs flow matching with discrete scheduling for efficient sampling and uses Google's T5Gemma-2B-2B-UL2 model for multi-language text encoding. The ~1.3B parameter transformer delivers fast inference without sacrificing quality. You can choose between Flux VAE (8x compression, 16 latent channels) for balanced quality and speed or DC-AE (32x compression, 32 latent channels) for latent compression and faster processing.
## Available models
PRX offers multiple variants with different VAE configurations, each optimized for specific resolutions. Base models excel with detailed prompts, capturing complex compositions and subtle details. Fine-tuned models trained on the [Alchemist dataset](https://huggingface.co/datasets/yandex/alchemist) improve aesthetic quality, especially with simpler prompts.

*This paper presents SANA-Sprint, an efficient diffusion model for ultra-fast text-to-image (T2I) generation. SANA-Sprint is built on a pre-trained foundation model and augmented with hybrid distillation, dramatically reducing inference steps from 20 to 1-4. We introduce three key innovations: (1) We propose a training-free approach that transforms a pre-trained flow-matching model for continuous-time consistency distillation (sCM), eliminating costly training from scratch and achieving high training efficiency. Our hybrid distillation strategy combines sCM with latent adversarial distillation (LADD): sCM ensures alignment with the teacher model, while LADD enhances single-step generation fidelity. (2) SANA-Sprint is a unified step-adaptive model that achieves high-quality generation in 1-4 steps, eliminating step-specific training and improving efficiency. (3) We integrate ControlNet with SANA-Sprint for real-time interactive image generation, enabling instant visual feedback for user interaction. SANA-Sprint establishes a new Pareto frontier in speed-quality tradeoffs, achieving state-of-the-art performance with 7.59 FID and 0.74 GenEval in only 1 step — outperforming FLUX-schnell (7.94 FID / 0.71 GenEval) while being 10× faster (0.1s vs 1.1s on H100). It also achieves 0.1s (T2I) and 0.25s (ControlNet) latency for 1024×1024 images on H100, and 0.31s (T2I) on an RTX 4090, showcasing its exceptional efficiency and potential for AI-powered consumer applications (AIPC). Code and pre-trained models will be open-sourced.*

[SANA-Video: Efficient Video Generation with Block Linear Diffusion Transformer](https://huggingface.co/papers/2509.24695) from NVIDIA and MIT HAN Lab, by Junsong Chen, Yuyang Zhao, Jincheng Yu, Ruihang Chu, Junyu Chen, Shuai Yang, Xianbang Wang, Yicheng Pan, Daquan Zhou, Huan Ling, Haozhe Liu, Hongwei Yi, Hao Zhang, Muyang Li, Yukang Chen, Han Cai, Sanja Fidler, Ping Luo, Song Han, Enze Xie.
The abstract from the paper is:
*We introduce SANA-Video, a small diffusion model that can efficiently generate videos up to 720x1280 resolution and minute-length duration. SANA-Video synthesizes high-resolution, high-quality and long videos with strong text-video alignment at a remarkably fast speed, deployable on RTX 5090 GPU. Two core designs ensure our efficient, effective and long video generation: (1) Linear DiT: We leverage linear attention as the core operation, which is more efficient than vanilla attention given the large number of tokens processed in video generation. (2) Constant-Memory KV cache for Block Linear Attention: we design block-wise autoregressive approach for long video generation by employing a constant-memory state, derived from the cumulative properties of linear attention. This KV cache provides the Linear DiT with global context at a fixed memory cost, eliminating the need for a traditional KV cache and enabling efficient, minute-long video generation. In addition, we explore effective data filters and model training strategies, narrowing the training cost to 12 days on 64 H100 GPUs, which is only 1% of the cost of MovieGen. Given its low cost, SANA-Video achieves competitive performance compared to modern state-of-the-art small diffusion models (e.g., Wan 2.1-1.3B and SkyReel-V2-1.3B) while being 16x faster in measured latency. Moreover, SANA-Video can be deployed on RTX 5090 GPUs with NVFP4 precision, accelerating the inference speed of generating a 5-second 720p video from 71s to 29s (2.4x speedup). In summary, SANA-Video enables low-cost, high-quality video generation. [this https URL](https://github.com/NVlabs/SANA).*

## Quantization
Quantization helps reduce the memory requirements of very large models by storing model weights in a lower precision data type. However, quantization may have varying impact on video quality depending on the video model.
Refer to the [Quantization](../../quantization/overview) overview to learn more about supported quantization backends and selecting a quantization backend that supports your use case. The example below demonstrates how to load a quantized [`SanaVideoPipeline`] for inference with bitsandbytes.

The black mask signifies that the model will not generate new content for that area, and only use those parts for conditioning the generation process. For parts/frames that should be generated by the model, the mask should be white in color.

### Wan-Animate: Unified Character Animation and Replacement with Holistic Replication
[Wan-Animate](https://huggingface.co/papers/2509.14055) by the Wan Team.
*We introduce Wan-Animate, a unified framework for character animation and replacement. Given a character image and a reference video, Wan-Animate can animate the character by precisely replicating the expressions and movements of the character in the video to generate high-fidelity character videos. Alternatively, it can integrate the animated character into the reference video to replace the original character, replicating the scene's lighting and color tone to achieve seamless environmental integration. Wan-Animate is built upon the Wan model. To adapt it for character animation tasks, we employ a modified input paradigm to differentiate between reference conditions and regions for generation. This design unifies multiple tasks into a common symbolic representation. We use spatially-aligned skeleton signals to replicate body motion and implicit facial features extracted from source images to reenact expressions, enabling the generation of character videos with high controllability and expressiveness. Furthermore, to enhance environmental integration during character replacement, we develop an auxiliary Relighting LoRA. This module preserves the character's appearance consistency while applying the appropriate environmental lighting and color tone. Experimental results demonstrate that Wan-Animate achieves state-of-the-art performance. We are committed to open-sourcing the model weights and its source code.*
The project page: https://humanaigc.github.io/wan-animate
This model was mostly contributed by [M. Tolga Cangöz](https://github.com/tolgacangoz).
#### Usage
The Wan-Animate pipeline supports two modes of operation:
1. **Animation Mode** (default): Animates a character image based on motion and expression from reference videos
2. **Replacement Mode**: Replaces a character in a background video with a new character while preserving the scene
##### Prerequisites
Before using the pipeline, you need to preprocess your reference video to extract:
- **Pose video**: Contains skeletal keypoints representing body motion
- **Face video**: Contains facial feature representations for expression control
For replacement mode, you additionally need:
- **Background video**: The original video containing the scene
- **Mask video**: A mask indicating where to generate content (white) vs. preserve original (black)
> [!NOTE]
> Raw videos should not be used for inputs such as `pose_video`, which the pipeline expects to be preprocessed to extract the proper information. Preprocessing scripts to prepare these inputs are available in the [original Wan-Animate repository](https://github.com/Wan-Video/Wan2.2?tab=readme-ov-file#1-preprocessing). Integration of these preprocessing steps into Diffusers is planned for a future release.
The example below demonstrates how to use the Wan-Animate pipeline:

#### Key Parameters
- **mode**: Choose between `"animate"` (default) or `"replace"`
- **prev_segment_conditioning_frames**: Number of frames for temporal guidance (1 or 5 recommended). Using 5 provides better temporal consistency but requires more memory
- **guidance_scale**: Controls how closely the output follows the text prompt. Higher values (5-7) produce results more aligned with the prompt. For Wan-Animate, CFG is disabled by default (`guidance_scale=1.0`) but can be enabled to support negative prompts and finer control over facial expressions. (Note that CFG will only target the text prompt and face conditioning.)

</div>
[Z-Image](https://huggingface.co/papers/2511.22699) is a powerful and highly efficient image generation model with 6B parameters. Currently there's only one model with two more to be released:
|Model|Hugging Face|
|---|---|
|Z-Image-Turbo|https://huggingface.co/Tongyi-MAI/Z-Image-Turbo|
## Z-Image-Turbo
Z-Image-Turbo is a distilled version of Z-Image that matches or exceeds leading competitors with only 8 NFEs (Number of Function Evaluations). It offers sub-second inference latency on enterprise-grade H800 GPUs and fits comfortably within 16G VRAM consumer devices. It excels in photorealistic image generation, bilingual text rendering (English & Chinese), and robust instruction adherence.
## Image-to-image
Use [`ZImageImg2ImgPipeline`] to transform an existing image based on a text prompt.
```python
import torch
from diffusers import ZImageImg2ImgPipeline
from diffusers.utils import load_image
pipe = ZImageImg2ImgPipeline.from_pretrained("Tongyi-MAI/Z-Image-Turbo", torch_dtype=torch.bfloat16)
pipe.to("cuda")
url = "https://raw.githubusercontent.com/CompVis/stable-diffusion/main/assets/stable-samples/img2img/sketch-mountains-input.jpg"
init_image = load_image(url).resize((1024, 1024))
prompt = "A fantasy landscape with mountains and a river, detailed, vibrant colors"
image = pipe(
prompt,
image=init_image,
strength=0.6,
num_inference_steps=9,

# Building Custom Blocks
[ModularPipelineBlocks](./pipeline_block) are the fundamental building blocks of a [`ModularPipeline`]. You can create custom blocks by defining their inputs, outputs, and computation logic. This guide demonstrates how to create and use a custom block.
> [!TIP]
> Explore the [Modular Diffusers Custom Blocks](https://huggingface.co/collections/diffusers/modular-diffusers-custom-blocks) collection for official custom modular blocks like Nano Banana.
## Project Structure
Your custom block project should use the following structure:
```shell
.
├── block.py
└── modular_config.json
```
- `block.py` contains the custom block implementation
- `modular_config.json` contains the metadata needed to load the block
## Example: Florence 2 Inpainting Block
In this example we will create a custom block that uses the [Florence 2](https://huggingface.co/docs/transformers/model_doc/florence2) model to process an input image and generate a mask for inpainting.
The first step is to define the components that the block will use. In this case, we will need to use the `Florence2ForConditionalGeneration` model and its corresponding processor `AutoProcessor`. When defining components, we must specify the name of the component within our pipeline, model class via `type_hint`, and provide a `pretrained_model_name_or_path` for the component if we intend to load the model weights from a specific repository on the Hub.
```py
# Inside block.py
from diffusers.modular_pipelines import (
ModularPipelineBlocks,
ComponentSpec,
)
from transformers import AutoProcessor, Florence2ForConditionalGeneration
class Florence2ImageAnnotatorBlock(ModularPipelineBlocks):
@property
def expected_components(self):
return [
ComponentSpec(
name="image_annotator",
type_hint=Florence2ForConditionalGeneration,
pretrained_model_name_or_path="florence-community/Florence-2-base-ft",
),
ComponentSpec(
name="image_annotator_processor",
type_hint=AutoProcessor,
pretrained_model_name_or_path="florence-community/Florence-2-base-ft",
),
]
```
Next, we define the inputs and outputs of the block. The inputs include the image to be annotated, the annotation task, and the annotation prompt. The outputs include the generated mask image and annotations.
```py
from typing import List, Union
from PIL import Image, ImageDraw
import torch
import numpy as np
from diffusers.modular_pipelines import (
PipelineState,
ModularPipelineBlocks,
InputParam,
ComponentSpec,
OutputParam,
)
from transformers import AutoProcessor, Florence2ForConditionalGeneration
class Florence2ImageAnnotatorBlock(ModularPipelineBlocks):
@property
def expected_components(self):
return [
ComponentSpec(
name="image_annotator",
type_hint=Florence2ForConditionalGeneration,
pretrained_model_name_or_path="florence-community/Florence-2-base-ft",
),
ComponentSpec(
name="image_annotator_processor",
type_hint=AutoProcessor,
pretrained_model_name_or_path="florence-community/Florence-2-base-ft",
),
]
@property
def inputs(self) -> List[InputParam]:
return [
InputParam(
"image",
type_hint=Union[Image.Image, List[Image.Image]],
required=True,
description="Image(s) to annotate",
),
InputParam(
"annotation_task",
type_hint=Union[str, List[str]],
required=True,
default="<REFERRING_EXPRESSION_SEGMENTATION>",
description="""Annotation Task to perform on the image.
Supported Tasks:
<OD>
<REFERRING_EXPRESSION_SEGMENTATION>
<CAPTION>
<DETAILED_CAPTION>
<MORE_DETAILED_CAPTION>
<DENSE_REGION_CAPTION>
<CAPTION_TO_PHRASE_GROUNDING>

""",
),
InputParam(
"annotation_prompt",
type_hint=Union[str, List[str]],
required=True,
description="""Annotation Prompt to provide more context to the task.

""",
),
InputParam(
"annotation_output_type",
type_hint=str,
required=True,
default="mask_image",
description="""Output type from annotation predictions. Availabe options are
mask_image:
-black and white mask image for the given image based on the task type
mask_overlay:

bounding_box:

""",
),
InputParam(
"annotation_overlay",
type_hint=bool,
required=True,
default=False,
description="",
),
]
@property
def intermediate_outputs(self) -> List[OutputParam]:
return [
OutputParam(
"mask_image",
type_hint=Image,

"annotations",
type_hint=dict,
description="Annotations Predictions for input Image(s)",
),
OutputParam(
"image",
type_hint=Image,
description="Annotated input Image(s)",
),
]
```
Now we implement the `__call__` method, which contains the logic for processing the input image and generating the mask.
```py

```
Once we have defined our custom block, we can save it to the Hub, using either the CLI or the [`push_to_hub`] method. This will make it easy to share and reuse our custom block with other pipelines.
<hfoptions id="share">
<hfoption id="hf CLI">
```shell
# In the folder with the `block.py` file, run:
diffusers-cli custom_block
```
Then upload the block to the Hub:
```shell
hf upload <your repo id> . .
```
</hfoption>
<hfoption id="push_to_hub">
```py
from block import Florence2ImageAnnotatorBlock
block = Florence2ImageAnnotatorBlock()
block.push_to_hub("<your repo id>")
```
</hfoption>
</hfoptions>
## Using Custom Blocks
Load the custom block with [`~ModularPipelineBlocks.from_pretrained`] and set `trust_remote_code=True`.
```py
import torch
from diffusers.modular_pipelines import ModularPipelineBlocks, SequentialPipelineBlocks
from diffusers.modular_pipelines.stable_diffusion_xl import INPAINT_BLOCKS
from diffusers.utils import load_image
# Fetch the Florence2 image annotator block that will create our mask
image_annotator_block = ModularPipelineBlocks.from_pretrained("diffusers/florence-2-custom-block", trust_remote_code=True)
my_blocks = INPAINT_BLOCKS.copy()
# insert the annotation block before the image encoding step
my_blocks.insert("image_annotator", image_annotator_block, 1)
# Create our initial set of inpainting blocks
blocks = SequentialPipelineBlocks.from_blocks_dict(my_blocks)
repo_id = "diffusers/modular-stable-diffusion-xl-base-1.0"
pipe = blocks.init_pipeline(repo_id)
pipe.load_components(torch_dtype=torch.float16, device_map="cuda", trust_remote_code=True)
image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/car.jpg?download=true")
image = image.resize((1024, 1024))
prompt = ["A red car"]
annotation_task = "<REFERRING_EXPRESSION_SEGMENTATION>"
annotation_prompt = ["the car"]
output = pipe(
prompt=prompt,
image=image,
annotation_task=annotation_task,
annotation_prompt=annotation_prompt,
annotation_output_type="mask_image",
num_inference_steps=35,
guidance_scale=7.5,
strength=0.95,
output="images"
)
output[0].save("florence-inpainting.png")
```
## Editing Custom Blocks
By default, custom blocks are saved in your cache directory. Use the `local_dir` argument to download and edit a custom block in a specific folder.
```py
import torch
from diffusers.modular_pipelines import ModularPipelineBlocks, SequentialPipelineBlocks
from diffusers.modular_pipelines.stable_diffusion_xl import INPAINT_BLOCKS
from diffusers.utils import load_image
# Fetch the Florence2 image annotator block that will create our mask
image_annotator_block = ModularPipelineBlocks.from_pretrained("diffusers/florence-2-custom-block", trust_remote_code=True, local_dir="/my-local-folder")
```
Any changes made to the block files in this folder will be reflected when you load the block again.

2. Data type checks confirm tensors have matching dtypes and use either bfloat16 or float16.
3. Shape checks validate tensor dimensions and prevent mixing attention masks with causal flags.
Enable these checks by setting the `DIFFUSERS_ATTN_CHECKS` environment variable. Checks add overhead to every attention operation, so they're disabled by default.
```bash
export DIFFUSERS_ATTN_CHECKS=yes
```
The checks are run now before every attention operation.

key = torch.randn(1, 10, 8, 64, dtype=torch.bfloat16, device="cuda")

with attention_backend("flash"):
output = dispatch_attention_fn(query, key, value)

## TaylorSeer Cache
[TaylorSeer Cache](https://huggingface.co/papers/2403.06923) accelerates diffusion inference by using Taylor series expansions to approximate and cache intermediate activations across denoising steps. The method predicts future outputs based on past computations, reusing them at specified intervals to reduce redundant calculations.
This caching mechanism delivers strong results with minimal additional memory overhead. For detailed performance analysis, see [our findings here](https://github.com/huggingface/diffusers/pull/12648#issuecomment-3610615080).
To enable TaylorSeer Cache, create a [`TaylorSeerCacheConfig`] and pass it to your pipeline's transformer:
- `cache_interval`: Number of steps to reuse cached outputs before performing a full forward pass
- `disable_cache_before_step`: Initial steps that use full computations to gather data for approximations
- `max_order`: Approximation accuracy (in theory, higher values improve quality but increase memory usage but we recommend it should be set to `1`)
```python
import torch
from diffusers import FluxPipeline, TaylorSeerCacheConfig
pipe = FluxPipeline.from_pretrained(
"black-forest-labs/FLUX.1-dev",
torch_dtype=torch.bfloat16,
)
pipe.to("cuda")

# AutoModel
The [`AutoModel`] class automatically detects and loads the correct model class (UNet, transformer, VAE) from a `config.json` file. You don't need to know the specific model class name ahead of time. It supports data types and device placement, and works across model types and libraries.
The example below loads a transformer from Diffusers and a text encoder from Transformers. Use the `subfolder` parameter to specify where to load the `config.json` file from.
```py
import torch
from diffusers import AutoModel, DiffusionPipeline
transformer = AutoModel.from_pretrained(
"Qwen/Qwen-Image", subfolder="transformer", torch_dtype=torch.bfloat16, device_map="cuda"
)
text_encoder = AutoModel.from_pretrained(
"Qwen/Qwen-Image", subfolder="text_encoder", torch_dtype=torch.bfloat16, device_map="cuda"
)
```
[`AutoModel`] also loads models from the [Hub](https://huggingface.co/models) that aren't included in Diffusers. Set `trust_remote_code=True` in [`AutoModel.from_pretrained`] to load custom models.
```py
import torch
from diffusers import AutoModel
transformer = AutoModel.from_pretrained(
"custom/custom-transformer-model", trust_remote_code=True, torch_dtype=torch.bfloat16, device_map="cuda"
)
```
If the custom model inherits from the [`ModelMixin`] class, it gets access to the same features as Diffusers model classes, like [regional compilation](../optimization/fp16#regional-compilation) and [group offloading](../optimization/memory#group-offloading).

[InstructPix2Pix](../api/pipelines/pix2pix) is fine-tuned from Stable Diffusion to support editing input images. It takes as inputs an image and a prompt describing an edit, and it outputs the edited image.
InstructPix2Pix has been explicitly trained to work well with [InstructGPT](https://openai.com/blog/instruction-following/)-like prompts.
## Pix2Pix Zero
[Paper](https://huggingface.co/papers/2302.03027)
[Pix2Pix Zero](../api/pipelines/pix2pix_zero) allows modifying an image so that one concept or subject is translated to another one while preserving general image semantics.
The denoising process is guided from one conceptual embedding towards another conceptual embedding. The intermediate latents are optimized during the denoising process to push the attention maps towards reference attention maps. The reference attention maps are from the denoising process of the input image and are used to encourage semantic preservation.
Pix2Pix Zero can be used both to edit synthetic images as well as real images.
- To edit synthetic images, one first generates an image given a caption.
Next, we generate image captions for the concept that shall be edited and for the new target concept. We can use a model like [Flan-T5](https://huggingface.co/docs/transformers/model_doc/flan-t5) for this purpose. Then, "mean" prompt embeddings for both the source and target concepts are created via the text encoder. Finally, the pix2pix-zero algorithm is used to edit the synthetic image.
- To edit a real image, one first generates an image caption using a model like [BLIP](https://huggingface.co/docs/transformers/model_doc/blip). Then one applies DDIM inversion on the prompt and image to generate "inverse" latents. Similar to before, "mean" prompt embeddings for both source and target concepts are created and finally the pix2pix-zero algorithm in combination with the "inverse" latents is used to edit the image.
> [!TIP]
> Pix2Pix Zero is the first model that allows "zero-shot" image editing. This means that the model
> can edit an image in less than a minute on a consumer GPU as shown [here](../api/pipelines/pix2pix_zero#usage-example).
As mentioned above, Pix2Pix Zero includes optimizing the latents (and not any of the UNet, VAE, or the text encoder) to steer the generation toward a specific concept. This means that the overall
pipeline might require more memory than a standard [StableDiffusionPipeline](../api/pipelines/stable_diffusion/text2img).
> [!TIP]
> An important distinction between methods like InstructPix2Pix and Pix2Pix Zero is that the former
> involves fine-tuning the pre-trained weights while the latter does not. This means that you can
> apply Pix2Pix Zero to any of the available Stable Diffusion models.

## Model Editing
[Paper](https://huggingface.co/papers/2303.08084)
The [text-to-image model editing pipeline](../api/pipelines/model_editing) helps you mitigate some of the incorrect implicit assumptions a pre-trained text-to-image
diffusion model might make about the subjects present in the input prompt. For example, if you prompt Stable Diffusion to generate images for "A pack of roses", the roses in the generated images
are more likely to be red. This pipeline helps you change that assumption.
