2ca3cadb35 [perf] Cache version checks
I recently noticed that we are spending a non-negligible amount of time in `version.parse` when running pipelines (approx. ~50ms per step for the QwenImageEdit pipeline on a ZeroGPU Space for instance, which in this case represents almost 10% of the actual compute). The calls to those version checks originate from:
- 4588bbeb42/src/diffusers/hooks/hooks.py (L277)

Maybe that the issue can otherwise be solved from root (why do we need to unwrap the modules at each call?) or maybe that my particular setup triggered this? (I patched the forward method at the blocks level but I don't feel like it has an incidence over _set_context)

# 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.
its not recommended to use freeform text prompts directly with FIBO, as it will not produce the best results.
you can learn more about FIBO in [Bria Fibo Hugging Face page](https://huggingface.co/briaai/FIBO).
## 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._
Use the command below to log in:

# 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.

"The mouses pose should be natural—perhaps sitting upright with paws resting lightly on the rim or submerged in the tea.

# 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,

- 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.

# 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.

The general rule of thumb to keep in mind when preparing inputs for the VACE pipeline is that the input images, or frames of a video that you want to use for conditioning, should have a corresponding mask that is black in color. 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.)

> 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,

ComponentSpec,

class Florence2ImageAnnotatorBlock(ModularPipelineBlocks):

return [

),

name="image_annotator_processor",
type_hint=AutoProcessor,

),
]
@property
def inputs(self) -> List[InputParam]:
return [
InputParam(

),
InputParam(
"annotation_task",

required=True,
default="<REFERRING_EXPRESSION_SEGMENTATION>",
description="""Annotation Task to perform on the image.

),
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

-black and white mask image for the given image based on the task type

""",
),
InputParam(
"annotation_overlay",
type_hint=bool,
required=True,
default=False,
description="",

]
@property
def intermediate_outputs(self) -> List[OutputParam]:
return [

OutputParam(
"image",
type_hint=Image,

```

```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.

The attention dispatcher includes debugging checks that catch common errors before they cause problems.
1. Device checks verify that query, key, and value tensors live on the same device.
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.

# 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.

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

Once you have generated an image, you can pass it to the SDXL refiner model to enhance final generation quality.
Generate an image from the base model, and set the model output to **latent** space:

# Prompt techniques
[[open-in-colab]]
# Prompting
Prompts are important because they describe what you want a diffusion model to generate. The best prompts are detailed, specific, and well-structured to help the model realize your vision. But crafting a great prompt takes time and effort and sometimes it may not be enough because language and words can be imprecise. This is where you need to boost your prompt with other techniques, such as prompt enhancing and prompt weighting, to get the results you want.
Prompts describes what a model should generate. Good prompts are detailed, specific, and structured and they generate better images and videos.
This guide will show you how you can use these prompt techniques to generate high-quality images with lower effort and adjust the weight of certain keywords in a prompt.
This guide shows you how to write effective prompts and introduces techniques that make them stronger.
## Prompt engineering
## Writing good prompts
> [!TIP]
> This is not an exhaustive guide on prompt engineering, but it will help you understand the necessary parts of a good prompt. We encourage you to continue experimenting with different prompts and combine them in new ways to see what works best. As you write more prompts, you'll develop an intuition for what works and what doesn't!
Every effective prompt needs three core elements.
New diffusion models do a pretty good job of generating high-quality images from a basic prompt, but it is still important to create a well-written prompt to get the best results. Here are a few tips for writing a good prompt:
1. <span class="underline decoration-sky-500 decoration-2 underline-offset-4">Subject</span> - what you want to generate. Start your prompt here.
2. <span class="underline decoration-pink-500 decoration-2 underline-offset-4">Style</span> - the medium or aesthetic. How should it look?
3. <span class="underline decoration-green-500 decoration-2 underline-offset-4">Context</span> - details about actions, setting, and mood.
Use these elements as a structured narrative, not a keyword list. Modern models understand language better than keyword matching. Start simple, then add details.
Context is especially important for creating better prompts. Try adding lighting, artistic details, and mood.
1. What is the image *medium*? Is it a photo, a painting, a 3D illustration, or something else?
2. What is the image *subject*? Is it a person, animal, object, or scene?
3. What *details* would you like to see in the image? This is where you can get really creative and have a lot of fun experimenting with different words to bring your image to life. For example, what is the lighting like? What is the vibe and aesthetic? What kind of art or illustration style are you looking for? The more specific and precise words you use, the better the model will understand what you want to generate.

Be specific and add context. Use photography terms like lens type, focal length, camera angles, and depth of field.
## Prompt enhancing with GPT2
Prompt enhancing is a technique for quickly improving prompt quality without spending too much effort constructing one. It uses a model like GPT2 pretrained on Stable Diffusion text prompts to automatically enrich a prompt with additional important keywords to generate high-quality images.
The technique works by curating a list of specific keywords and forcing the model to generate those words to enhance the original prompt. This way, your prompt can be "a cat" and GPT2 can enhance the prompt to "cinematic film still of a cat basking in the sun on a roof in Turkey, highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain quality sharp focus beautiful detailed intricate stunning amazing epic".
> [!TIP]
> Try a [prompt enhancer](https://huggingface.co/models?sort=downloads&search=prompt+enhancer) to help improve your prompt structure.
> You should also use a [*offset noise*](https://www.crosslabs.org//blog/diffusion-with-offset-noise) LoRA to improve the contrast in bright and dark images and create better lighting overall. This [LoRA](https://hf.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_offset_example-lora_1.0.safetensors) is available from [stabilityai/stable-diffusion-xl-base-1.0](https://hf.co/stabilityai/stable-diffusion-xl-base-1.0).
## Prompt weighting
Prompt weighting makes some words stronger and others weaker. It scales attention scores so you control how much influence each concept has.
Diffusers handles this through `prompt_embeds` and `pooled_prompt_embeds` arguments which take scaled text embedding vectors. Use the [sd_embed](https://github.com/xhinker/sd_embed) library to generate these embeddings. It also supports longer prompts.
> [!NOTE]
> The sd_embed library only supports Stable Diffusion, Stable Diffusion XL, Stable Diffusion 3, Stable Cascade, and Flux. Prompt weighting doesn't necessarily help for newer models like Flux which already has very good prompt adherence.
```py
!uv pip install git+https://github.com/xhinker/sd_embed.git@main
```
Format weighted text with numerical multipliers or parentheses. More parentheses mean stronger weighting.
| format | multiplier |
|---|---|
| `(cat)` | increase by 1.1x |
| `((cat))` | increase by 1.21x |
| `(cat:1.5)` | increase by 1.5x |
| `(cat:0.5)` | decrease by 4x |
Create a weighted prompt and pass it to [get_weighted_text_embeddings_sdxl](https://github.com/xhinker/sd_embed/blob/4a47f71150a22942fa606fb741a1c971d95ba56f/src/sd_embed/embedding_funcs.py#L405) to generate embeddings.
> [!TIP]
> You could also pass negative prompts to `negative_prompt_embeds` and `negative_pooled_prompt_embeds`.
Start by defining certain styles and a list of words (you can check out a more comprehensive list of [words](https://hf.co/LykosAI/GPT-Prompt-Expansion-Fooocus-v2/blob/main/positive.txt) and [styles](https://github.com/lllyasviel/Fooocus/tree/main/sdxl_styles) used by Fooocus) to enhance a prompt with.
```py
import torch
from diffusers import DiffusionPipeline
from sd_embed.embedding_funcs import get_weighted_text_embeddings_sdxl
from transformers import GenerationConfig, GPT2LMHeadModel, GPT2Tokenizer, LogitsProcessor, LogitsProcessorList
from diffusers import StableDiffusionXLPipeline
pipeline = DiffusionPipeline.from_pretrained(
"Lykon/dreamshaper-xl-1-0", torch_dtype=torch.bfloat16, device_map="cuda"
)
styles = {
"cinematic": "cinematic film still of {prompt}, highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain",
"anime": "anime artwork of {prompt}, anime style, key visual, vibrant, studio anime, highly detailed",
"photographic": "cinematic photo of {prompt}, 35mm photograph, film, professional, 4k, highly detailed",
"comic": "comic of {prompt}, graphic illustration, comic art, graphic novel art, vibrant, highly detailed",
"lineart": "line art drawing {prompt}, professional, sleek, modern, minimalist, graphic, line art, vector graphics",
"pixelart": " pixel-art {prompt}, low-res, blocky, pixel art style, 8-bit graphics",
}
prompt = """

Gentle ripples reflect pastel skies, while (sunlight:1.1) casts soft highlights. The illustration is smooth and polished
with elegant, sketchy lines and subtle gradients, evoking a ((whimsical, nostalgic, dreamy lofi atmosphere:2.0)),

"""
prompt_embeds, _, pooled_prompt_embeds, *_ = get_weighted_text_embeddings_sdxl(pipeline, prompt=prompt)
words = [
"aesthetic", "astonishing", "beautiful", "breathtaking", "composition", "contrasted", "epic", "moody", "enhanced",
"exceptional", "fascinating", "flawless", "glamorous", "glorious", "illumination", "impressive", "improved",
"inspirational", "magnificent", "majestic", "hyperrealistic", "smooth", "sharp", "focus", "stunning", "detailed",
"intricate", "dramatic", "high", "quality", "perfect", "light", "ultra", "highly", "radiant", "satisfying",
"soothing", "sophisticated", "stylish", "sublime", "terrific", "touching", "timeless", "wonderful", "unbelievable",
"elegant", "awesome", "amazing", "dynamic", "trendy",
]
```
Pass the embeddings to `prompt_embeds` and `pooled_prompt_embeds` to generate your image.
You may have noticed in the `words` list, there are certain words that can be paired together to create something more meaningful. For example, the words "high" and "quality" can be combined to create "high quality". Let's pair these words together and remove the words that can't be paired.
```py
image = pipeline(prompt_embeds=prompt_embeds, pooled_prompt_embeds=pooled_prompt_embeds).images[0]
word_pairs = ["highly detailed", "high quality", "enhanced quality", "perfect composition", "dynamic light"]
def find_and_order_pairs(s, pairs):
words = s.split()
found_pairs = []
for pair in pairs:
pair_words = pair.split()
if pair_words[0] in words and pair_words[1] in words:
found_pairs.append(pair)
words.remove(pair_words[0])
words.remove(pair_words[1])
for word in words[:]:
for pair in pairs:
if word in pair.split():
words.remove(word)
break
ordered_pairs = ", ".join(found_pairs)
remaining_s = ", ".join(words)
return ordered_pairs, remaining_s
```
Next, implement a custom [`~transformers.LogitsProcessor`] class that assigns tokens in the `words` list a value of 0 and assigns tokens not in the `words` list a negative value so they aren't picked during generation. This way, generation is biased towards words in the `words` list. After a word from the list is used, it is also assigned a negative value so it isn't picked again.
```py
class CustomLogitsProcessor(LogitsProcessor):
def __init__(self, bias):
super().__init__()
self.bias = bias
def __call__(self, input_ids, scores):
if len(input_ids.shape) == 2:
last_token_id = input_ids[0, -1]
self.bias[last_token_id] = -1e10
return scores + self.bias
word_ids = [tokenizer.encode(word, add_prefix_space=True)[0] for word in words]
bias = torch.full((tokenizer.vocab_size,), -float("Inf")).to("cuda")
bias[word_ids] = 0
processor = CustomLogitsProcessor(bias)
processor_list = LogitsProcessorList([processor])
```
Combine the prompt and the `cinematic` style prompt defined in the `styles` dictionary earlier.
```py
prompt = "a cat basking in the sun on a roof in Turkey"
style = "cinematic"
prompt = styles[style].format(prompt=prompt)
prompt
"cinematic film still of a cat basking in the sun on a roof in Turkey, highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain"
```
Load a GPT2 tokenizer and model from the [Gustavosta/MagicPrompt-Stable-Diffusion](https://huggingface.co/Gustavosta/MagicPrompt-Stable-Diffusion) checkpoint (this specific checkpoint is trained to generate prompts) to enhance the prompt.
```py
tokenizer = GPT2Tokenizer.from_pretrained("Gustavosta/MagicPrompt-Stable-Diffusion")
model = GPT2LMHeadModel.from_pretrained("Gustavosta/MagicPrompt-Stable-Diffusion", torch_dtype=torch.float16).to(
"cuda"
)
model.eval()
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
token_count = inputs["input_ids"].shape[1]
max_new_tokens = 50 - token_count
generation_config = GenerationConfig(
penalty_alpha=0.7,
top_k=50,
eos_token_id=model.config.eos_token_id,
pad_token_id=model.config.eos_token_id,
pad_token=model.config.pad_token_id,
do_sample=True,
)
with torch.no_grad():
generated_ids = model.generate(
input_ids=inputs["input_ids"],
attention_mask=inputs["attention_mask"],
max_new_tokens=max_new_tokens,
generation_config=generation_config,
logits_processor=proccesor_list,
)
```
Then you can combine the input prompt and the generated prompt. Feel free to take a look at what the generated prompt (`generated_part`) is, the word pairs that were found (`pairs`), and the remaining words (`words`). This is all packed together in the `enhanced_prompt`.
```py
output_tokens = [tokenizer.decode(generated_id, skip_special_tokens=True) for generated_id in generated_ids]
input_part, generated_part = output_tokens[0][: len(prompt)], output_tokens[0][len(prompt) :]
pairs, words = find_and_order_pairs(generated_part, word_pairs)
formatted_generated_part = pairs + ", " + words
enhanced_prompt = input_part + ", " + formatted_generated_part
enhanced_prompt
["cinematic film still of a cat basking in the sun on a roof in Turkey, highly detailed, high budget hollywood movie, cinemascope, moody, epic, gorgeous, film grain quality sharp focus beautiful detailed intricate stunning amazing epic"]
```
Finally, load a pipeline and the offset noise LoRA with a *low weight* to generate an image with the enhanced prompt.
```py
pipeline = StableDiffusionXLPipeline.from_pretrained(
"RunDiffusion/Juggernaut-XL-v9", torch_dtype=torch.float16, variant="fp16"
).to("cuda")
pipeline.load_lora_weights(
"stabilityai/stable-diffusion-xl-base-1.0",
weight_name="sd_xl_offset_example-lora_1.0.safetensors",
adapter_name="offset",
)
pipeline.set_adapters(["offset"], adapter_weights=[0.2])
image = pipeline(
enhanced_prompt,
width=1152,
height=896,
guidance_scale=7.5,
num_inference_steps=25,
).images[0]

## Prompt weighting
Prompt weighting provides a way to emphasize or de-emphasize certain parts of a prompt, allowing for more control over the generated image. A prompt can include several concepts, which gets turned into contextualized text embeddings. The embeddings are used by the model to condition its cross-attention layers to generate an image (read the Stable Diffusion [blog post](https://huggingface.co/blog/stable_diffusion) to learn more about how it works).
Prompt weighting works by increasing or decreasing the scale of the text embedding vector that corresponds to its concept in the prompt because you may not necessarily want the model to focus on all concepts equally. The easiest way to prepare the prompt embeddings is to use [Stable Diffusion Long Prompt Weighted Embedding](https://github.com/xhinker/sd_embed) (sd_embed). Once you have the prompt-weighted embeddings, you can pass them to any pipeline that has a [prompt_embeds](https://huggingface.co/docs/diffusers/en/api/pipelines/stable_diffusion/text2img#diffusers.StableDiffusionPipeline.__call__.prompt_embeds) (and optionally [negative_prompt_embeds](https://huggingface.co/docs/diffusers/en/api/pipelines/stable_diffusion/text2img#diffusers.StableDiffusionPipeline.__call__.negative_prompt_embeds)) parameter, such as [`StableDiffusionPipeline`], [`StableDiffusionControlNetPipeline`], and [`StableDiffusionXLPipeline`].
> [!TIP]
> If your favorite pipeline doesn't have a `prompt_embeds` parameter, please open an [issue](https://github.com/huggingface/diffusers/issues/new/choose) so we can add it!
This guide will show you how to weight your prompts with sd_embed.
Before you begin, make sure you have the latest version of sd_embed installed:
```bash
pip install git+https://github.com/xhinker/sd_embed.git@main
```
For this example, let's use [`StableDiffusionXLPipeline`].
```py
from diffusers import StableDiffusionXLPipeline, UniPCMultistepScheduler
import torch
pipe = StableDiffusionXLPipeline.from_pretrained("Lykon/dreamshaper-xl-1-0", torch_dtype=torch.float16)
pipe.scheduler = UniPCMultistepScheduler.from_config(pipe.scheduler.config)
pipe.to("cuda")
```
To upweight or downweight a concept, surround the text with parentheses. More parentheses applies a heavier weight on the text. You can also append a numerical multiplier to the text to indicate how much you want to increase or decrease its weights by.
| format | multiplier |
|---|---|
| `(hippo)` | increase by 1.1x |
| `((hippo))` | increase by 1.21x |
| `(hippo:1.5)` | increase by 1.5x |
| `(hippo:0.5)` | decrease by 4x |
Create a prompt and use a combination of parentheses and numerical multipliers to upweight various text.
```py
from sd_embed.embedding_funcs import get_weighted_text_embeddings_sdxl
prompt = """A whimsical and creative image depicting a hybrid creature that is a mix of a waffle and a hippopotamus.
This imaginative creature features the distinctive, bulky body of a hippo,
but with a texture and appearance resembling a golden-brown, crispy waffle.
The creature might have elements like waffle squares across its skin and a syrup-like sheen.
It's set in a surreal environment that playfully combines a natural water habitat of a hippo with elements of a breakfast table setting,
possibly including oversized utensils or plates in the background.
The image should evoke a sense of playful absurdity and culinary fantasy.
"""
neg_prompt = """\

```
Use the `get_weighted_text_embeddings_sdxl` function to generate the prompt embeddings and the negative prompt embeddings. It'll also generated the pooled and negative pooled prompt embeddings since you're using the SDXL model.
> [!TIP]
> You can safely ignore the error message below about the token index length exceeding the models maximum sequence length. All your tokens will be used in the embedding process.
>
> ```
> Token indices sequence length is longer than the specified maximum sequence length for this model

Prompt weighting works with [Textual inversion](./textual_inversion_inference) and [DreamBooth](./dreambooth) adapters too.
> [!TIP]
> Refer to the [sd_embed](https://github.com/xhinker/sd_embed) repository for additional details about long prompt weighting for FLUX.1, Stable Cascade, and Stable Diffusion 1.5.
### Textual inversion
[Textual inversion](../training/text_inversion) is a technique for learning a specific concept from some images which you can use to generate new images conditioned on that concept.
Create a pipeline and use the [`~loaders.TextualInversionLoaderMixin.load_textual_inversion`] function to load the textual inversion embeddings (feel free to browse the [Stable Diffusion Conceptualizer](https://huggingface.co/spaces/sd-concepts-library/stable-diffusion-conceptualizer) for 100+ trained concepts):
```py
import torch
from diffusers import StableDiffusionPipeline
pipe = StableDiffusionPipeline.from_pretrained(
"stable-diffusion-v1-5/stable-diffusion-v1-5",
torch_dtype=torch.float16,
).to("cuda")
pipe.load_textual_inversion("sd-concepts-library/midjourney-style")
```
Add the `<midjourney-style>` text to the prompt to trigger the textual inversion.
```py
from sd_embed.embedding_funcs import get_weighted_text_embeddings_sd15
prompt = """<midjourney-style> A whimsical and creative image depicting a hybrid creature that is a mix of a waffle and a hippopotamus.
This imaginative creature features the distinctive, bulky body of a hippo,
but with a texture and appearance resembling a golden-brown, crispy waffle.
The creature might have elements like waffle squares across its skin and a syrup-like sheen.
It's set in a surreal environment that playfully combines a natural water habitat of a hippo with elements of a breakfast table setting,
possibly including oversized utensils or plates in the background.
The image should evoke a sense of playful absurdity and culinary fantasy.
"""
neg_prompt = """\
skin spots,acnes,skin blemishes,age spot,(ugly:1.2),(duplicate:1.2),(morbid:1.21),(mutilated:1.2),\
(tranny:1.2),mutated hands,(poorly drawn hands:1.5),blurry,(bad anatomy:1.2),(bad proportions:1.3),\
extra limbs,(disfigured:1.2),(missing arms:1.2),(extra legs:1.2),(fused fingers:1.5),\

bad hands,missing fingers,(extra arms and legs),(worst quality:2),(low quality:2),\
(normal quality:2),lowres,((monochrome)),((grayscale))
"""
```
Use the `get_weighted_text_embeddings_sd15` function to generate the prompt embeddings and the negative prompt embeddings.
```py
(
prompt_embeds,
prompt_neg_embeds,
) = get_weighted_text_embeddings_sd15(
pipe,
prompt=prompt,
neg_prompt=neg_prompt
)
image = pipe(
prompt_embeds=prompt_embeds,
negative_prompt_embeds=prompt_neg_embeds,
height=768,
width=896,
guidance_scale=4.0,
generator=torch.Generator("cuda").manual_seed(2)
).images[0]
image
```
<div class="flex justify-center">
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/sd_embed_textual_inversion.png"/>
</div>
### DreamBooth
[DreamBooth](../training/dreambooth) is a technique for generating contextualized images of a subject given just a few images of the subject to train on. It is similar to textual inversion, but DreamBooth trains the full model whereas textual inversion only fine-tunes the text embeddings. This means you should use [`~DiffusionPipeline.from_pretrained`] to load the DreamBooth model (feel free to browse the [Stable Diffusion Dreambooth Concepts Library](https://huggingface.co/sd-dreambooth-library) for 100+ trained models):
```py
import torch
from diffusers import DiffusionPipeline, UniPCMultistepScheduler
pipe = DiffusionPipeline.from_pretrained("sd-dreambooth-library/dndcoverart-v1", torch_dtype=torch.float16).to("cuda")
pipe.scheduler = UniPCMultistepScheduler.from_config(pipe.scheduler.config)
```
Depending on the model you use, you'll need to incorporate the model's unique identifier into your prompt. For example, the `dndcoverart-v1` model uses the identifier `dndcoverart`:
```py
from sd_embed.embedding_funcs import get_weighted_text_embeddings_sd15
prompt = """dndcoverart of A whimsical and creative image depicting a hybrid creature that is a mix of a waffle and a hippopotamus.
This imaginative creature features the distinctive, bulky body of a hippo,
but with a texture and appearance resembling a golden-brown, crispy waffle.
The creature might have elements like waffle squares across its skin and a syrup-like sheen.
It's set in a surreal environment that playfully combines a natural water habitat of a hippo with elements of a breakfast table setting,
possibly including oversized utensils or plates in the background.
The image should evoke a sense of playful absurdity and culinary fantasy.

This implementation of Flux Kontext allows users to pass multiple reference images. Each image is encoded separately, and the resulting latent vectors are concatenated.
As explained in Section 3 of [the paper](https://huggingface.co/papers/2506.15742), the model's sequence concatenation mechanism can extend its capabilities to handle multiple reference images. However, note that the current version of Flux Kontext was not trained for this use case. In practice, stacking along the first axis does not yield correct results, while stacking along the other two axes appears to work.
