DiffSynth Studio is a Diffusion engine. We have restructured architectures including Text Encoder, UNet, VAE, among others, maintaining compatibility with models from the open-source community while enhancing computational performance. We provide many interesting features. Enjoy the magic of Diffusion models!

Until now, DiffSynth Studio has supported the following models:

News

June 21, 2024. 🔥🔥🔥 We propose ExVideo, a post-tuning technique aimed at enhancing the capability of video generation models. We have extended Stable Video Diffusion to achieve the generation of long videos up to 128 frames.
- Project Page
- Source code is released in this repo. See examples/ExVideo.
- Models are released on HuggingFace and ModelScope.
- Technical report is released on arXiv.
- You can try ExVideo in this Demo!
June 13, 2024. DiffSynth Studio is transferred to ModelScope. The developers have transitioned from "I" to "we". Of course, I will still participate in development and maintenance.
Jan 29, 2024. We propose Diffutoon, a fantastic solution for toon shading.
- Project Page
- The source codes are released in this project.
- The technical report (IJCAI 2024) is released on arXiv.
Dec 8, 2023. We decide to develop a new Project, aiming to release the potential of diffusion models, especially in video synthesis. The development of this project is started.
Nov 15, 2023. We propose FastBlend, a powerful video deflickering algorithm.
- The sd-webui extension is released on GitHub.
- Demo videos are shown on Bilibili, including three tasks.
- The technical report is released on arXiv.
- An unofficial ComfyUI extension developed by other users is released on GitHub.
Oct 1, 2023. We release an early version of this project, namely FastSDXL. A try for building a diffusion engine.
- The source codes are released on GitHub.
- FastSDXL includes a trainable OLSS scheduler for efficiency improvement.
  - The original repo of OLSS is here.
  - The technical report (CIKM 2023) is released on arXiv.
  - A demo video is shown on Bilibili.
  - Since OLSS requires additional training, we don't implement it in this project.
Aug 29, 2023. We propose DiffSynth, a video synthesis framework.
- Project Page.
- The source codes are released in EasyNLP.
- The technical report (ECML PKDD 2024) is released on arXiv.

Installation

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

Usage (in Python code)

The Python examples are in examples. We provide an overview here.

Long Video Synthesis

We trained an extended video synthesis model, which can generate 128 frames. examples/ExVideo

Image Synthesis

Generate high-resolution images, by breaking the limitation of diffusion models! examples/image_synthesis.

LoRA fine-tuning is supported in examples/train.
