Hunyuan Video Review 2026 — Tencent's Open-Source Video Generation Model
Hunyuan Video by Tencent is the best open-source video generation model. 13B parameters, cinema-quality output, ComfyUI compatible. Free for non-commercial use.
HunyuanVideo provides PyTorch model definitions, pretrained weights, inference code, sampling tools, a command-line workflow, and a local Gradio server for text-to-video generation. It supports 540p and 720p outputs, multiple aspect ratios, configurable video length, sampling steps, seeds, and CPU offloading.
The project is aimed at researchers, developers, and creators running models locally. It requires Linux, CUDA, and a high-memory NVIDIA GPU; the repository documents at least 45GB of GPU memory for lower-resolution generation. It is not presented as a hosted subscription service, and GPU, cloud, and infrastructure costs are separate.
