What HunyuanVideo is
HunyuanVideo is an open-source video foundation model with PyTorch definitions, pretrained weights, and inference code for generating video from text or images. It supports text-to-video and image-to-video workflows, with listed maximum resolution of 1080p and commercial use permitted. The model has over 13 billion parameters and uses a decoder-only multimodal language model as its text encoder. Its unified architecture combines dual-stream and single-stream Transformer designs with full attention. Generation configurations include 540p and 720p at 129 frames. FP8 weights are available; the repository says they reduce GPU memory use by about 10GB. HunyuanVideo requires an NVIDIA CUDA GPU, with stated peaks of 60GB for 720p and 45GB for 544p generation. Linux is the tested operating system, with Docker images and an installation guide. Diffusers, xDiT parallel inference, and community ComfyUI tools are listed integrations.
