Introduction

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:

Installation

Install from source code (recommended):

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

Or install from pypi:

pip install diffsynth

Usage (in Python code)

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

Download Models

Download the pre-set models. Model IDs can be found in config file.

from diffsynth import download_models

download_models(["FLUX.1-dev", "Kolors"])

Download your own models.

from diffsynth.models.downloader import download_from_huggingface, download_from_modelscope

# From Modelscope (recommended)
download_from_modelscope("Kwai-Kolors/Kolors", "vae/diffusion_pytorch_model.fp16.bin", "models/kolors/Kolors/vae")
# From Huggingface
download_from_huggingface("Kwai-Kolors/Kolors", "vae/diffusion_pytorch_model.fp16.safetensors", "models/kolors/Kolors/vae")

Video Synthesis

Text-to-video using CogVideoX-5B

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.

Long Video Synthesis

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