About HunyuanVideo
HunyuanVideo is an open research framework from Tencent for large video generation models. The project publishes model code, pretrained weights and inference scripts for people who want to run video generation on their own hardware.
What it does
The repository holds PyTorch model definitions, pretrained checkpoints and sampling code. It covers text-to-video and image-to-video generation. The project has also released newer versions and related models, such as avatar animation and customized video generation, built on the same base. You run it locally, with a Gradio demo server included in the code.
Key features
- Text to video generation
- Image to video generation
- Pretrained weights and sampling scripts
- Gradio demo server included
- FP8 weights for lower GPU memory use
Who it's for
Researchers, machine learning engineers and hobbyists who can set up Python and PyTorch and have a suitable GPU. Teams that want to study or fine-tune an open video model will find the code more useful than a hosted product.
Pricing and good to know
The code and weights are free to download from the public GitHub repository. Check the LICENSE file in the repository before any commercial use. Running the model needs a large amount of GPU memory and some setup time, so it is best suited to a machine with a strong graphics card.
Highlights
- Generate video from a text prompt
- Animate a still image into a video
- Run the sampling scripts on your own GPU
- Use the included Gradio demo server
- Load lower-memory FP8 weights
