This release is a pre-release and may not be stable for production use.
OneDiff
OneDiff is an out-of-the-box acceleration library for diffusion models, it provides:
- PyTorch Module compilation tools and strong optimized GPU Kernels for diffusion models
- Out-of-the-box acceleration for popular UIs/libs
For example:
OneDiff is the abbreviation of "one line of code to accelerate diffusion models".

Architecture
OneDiff interfaces with various front-end sd frameworks upward, and uses a custom virtual machine mixed with PyTorch as the inference engine downward.
State-of-the-art performance
SDXL E2E time
- Model stabilityai/stable-diffusion-xl-base-1.0;
- Image size 1024*1024, batch size 1, steps 30;
- NVIDIA A100 80G SXM4;
SVD E2E time
- Model stabilityai/stable-video-diffusion-img2vid-xt;
- Image size 576*1024, batch size 1, steps 25, decoder chunk size 5;
- NVIDIA A100 80G SXM4;
Note that we haven't got the way to run SVD with TensorRT on Feb 29 2024.

Acceleration for production environment
PyTorch Module compilation
Avoid compilation time for new input shape
Avoid compilation time for online serving
Compile and save the compiled result offline, then load it online for serving
- Save and Load the compiled graph
- Change device of the compiled graph to do multi-process serving
- Compile at one device(such as device 0), then use the compiled result to other device(such as device 1~7).
OneDiff Quality Evaluation
We also maintain a repository for benchmarking the quality of generation after acceleration using OneDiff: OneDiffGenMetrics

Installation
OneDiff Installation
Install a compiler backend
When considering the choice between OneFlow and Nexfort, either one is optional, and only one is needed.
-
For DiT structural models or H100 devices, it is recommended to use Nexfort.
-
For all other cases, it is recommended to use OneFlow. Note that optimizations within OneFlow will gradually transition to Nexfort in the future.
(Optional) Install Nexfort
The detailed introduction of Nexfort is here.
python3 -m pip install -U torch==2.3.0 torchvision==0.18.0 torchaudio==2.3.0 torchao==0.1
python3 -m pip install -U nexfort
(Optional) Install OneFlow
NOTE: We have updated OneFlow frequently for OneDiff, so please install OneFlow by the links below.
-
CUDA 11.8
For NA/EU users
python3 -m pip install -U --pre oneflow -f https://github.com/siliconflow/oneflow_releases/releases/expanded_assets/community_cu118
For CN users
python3 -m pip install -U --pre oneflow -f https://oneflow-pro.oss-cn-beijing.aliyuncs.com/branch/community/cu118

CUDA 12.1
For NA/EU users
python3 -m pip install -U --pre oneflow -f https://github.com/siliconflow/oneflow_releases/releases/expanded_assets/community_cu121
For CN users
python3 -m pip install -U --pre oneflow -f https://oneflow-pro.oss-cn-beijing.aliyuncs.com/branch/community/cu121
-
CUDA 12.2
For NA/EU users
python3 -m pip install -U --pre oneflow -f https://github.com/siliconflow/oneflow_releases/releases/expanded_assets/community_cu122
For CN users
python3 -m pip install -U --pre oneflow -f https://oneflow-pro.oss-cn-beijing.aliyuncs.com/branch/community/cu122
2. Install torch and diffusers
Note: You can choose the latest versions you want for diffusers or transformers.
python3 -m pip install "torch" "transformers==4.27.1" "diffusers[torch]==0.19.3"
3. Install OneDiff
- From PyPI
python3 -m pip install --pre onediff
- From source
git clone https://github.com/siliconflow/onediff.git
cd onediff && python3 -m pip install -e .
NOTE: If you intend to utilize plugins for ComfyUI/StableDiffusion-WebUI, we highly recommend installing OneDiff from the source rather than PyPI. This is necessary as you'll need to manually copy (or create a soft link) for the relevant code into the extension folder of these UIs/Libs.
4. (Optional)Login huggingface-cli
python3 -m pip install huggingface_hub
huggingface-cli login
