FastHunyuan Model Card
Model Details
FastHunyuan is an accelerated HunyuanVideo model. It can sample high quality videos with 6 diffusion steps. That brings around 8X speed up compared to the original HunyuanVideo with 50 steps.
- Developed by: Hao AI Lab
- License: tencent-hunyuan-community
- Distilled from: HunyuanVideo
- Github Repository: https://github.com/hao-ai-lab/FastVideo
Usage
- Clone Fastvideo repository and follow the inference instructions in the README.
- Alternatively, you can inference FastHunyuan using the official Hunyuan Video repository by setting the shift to 17, steps to 6, resolution to 720X1280X125, and cfg bigger than 6. We find that a large CFG scale generally leads to faster videos.
Training details
FastHunyuan is consistency distillated on the MixKit dataset with the following hyperparamters:
- Batch size: 16
- Resulotion: 720x1280
- Num of frames: 125
- Train steps: 320
- GPUs: 32
- LR: 1e-6
- Loss: huber
Evaluation
We provide some qualitative comparison between FastHunyuan 6 step inference v.s. the original Hunyuan with 6 step inference:
