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:

• CogVideo
• FLUX
• ExVideo
• Kolors
• Stable Diffusion 3
• Stable Video Diffusion
• Hunyuan-DiT
• RIFE
• ESRGAN
• Ip-Adapter
• AnimateDiff
• ControlNet
• Stable Diffusion XL
• Stable Diffusion

• August 22, 2024. CogVideoX-5B is supported in this project. See here. We provide several interesting features for this text-to-video model, including

  • Text to video
  • Video editing
  • Self-upscaling
  • Video interpolation

• August 22, 2024. We have implemented an interesting painter that supports all text-to-image models. Now you can create stunning images using the painter, with assistance from AI!

  • Use it in our WebUI.

• August 21, 2024. FLUX is supported in DiffSynth-Studio.

  • Enable CFG and highres-fix to improve visual quality. See here
  • LoRA, ControlNet, and additional models will be available soon.

• 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.
    • Video deflickering
    • Video interpolation
    • Image-driven video rendering
  • 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.

CogVideoX-5B is released by ZhiPu. We provide an improved pipeline, supporting text-to-video, video editing, self-upscaling and video interpolation. examples/video_synthesis

The video on the left is generated using the original text-to-video pipeline, while the video on the right is the result after editing and frame interpolation.

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

Render realistic videos in a flatten style and enable video editing features. examples/Diffutoon

Video stylization without video models. examples/diffsynth

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

LoRA fine-tuning is supported in examples/train.
