About Hunyuan GameCraft

HunyuanVideo is an open-source AI framework developed by Tencent for large-scale video generation. It includes multiple models: text-to-video (HunyuanVideo), image-to-video (HunyuanVideo-I2V), audio-driven human animation (HunyuanVideo-Avatar), and customized video generation (HunyuanCustom). The repository provides PyTorch model definitions, pre-trained weights, inference/sampling code, and supports community integrations such as ComfyUI, Diffusers, and various acceleration techniques. It is designed for researchers and developers building video generation applications.
