## Introduction

Welcome to the magic world of Diffusion models! DiffSynth-Studio is an open-source Diffusion model engine developed and maintained by [ModelScope](https://www.modelscope.cn/) team. We aim to foster technical innovation through framework development, bring together the power of the open-source community, and explore the limits of generative models!

DiffSynth currently includes two open-source projects:
* [DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio): Focused on aggressive technical exploration, for academia, providing support for more cutting-edge model capabilities.
* [DiffSynth-Engine](https://github.com/modelscope/DiffSynth-Engine): Focused on stable model deployment, for industry, offering higher computing performance and more stable features.

[DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio) and [DiffSynth-Engine](https://github.com/modelscope/DiffSynth-Engine) are the core projects behind ModelScope [AIGC zone](https://modelscope.cn/aigc/home), offering powerful AI content generation abilities. Come and try our carefully designed features and start your AI creation journey!

## Installation

Install from source (recommended):

```
git clone https://github.com/modelscope/DiffSynth-Studio.git  
cd DiffSynth-Studio
pip install -e .
```

<summary>Other installation methods</summary>

Install from PyPI (version updates may be delayed; for latest features, install from source)

```
pip install diffsynth
```

If you meet problems during installation, they might be caused by upstream dependencies. Please check the docs of these packages:

* [torch](https://pytorch.org/get-started/locally/)
* [sentencepiece](https://github.com/google/sentencepiece)
* [cmake](https://cmake.org)
* [cupy](https://docs.cupy.dev/en/stable/install.html)

## Basic Framework

DiffSynth-Studio redesigns the inference and training pipelines for mainstream Diffusion models (including FLUX, Wan, etc.), enabling efficient memory management and flexible model training.
