HunyuanVideo

Tencent's open-weight 8.3B video model that runs on consumer GPUs

About HunyuanVideo

HunyuanVideo is Tencent's open-weight video generation family. The current 1.5 release is an 8.3B-parameter diffusion transformer for text-to-video and image-to-video at 480p and 720p, with a separate super-resolution model that upscales to 1080p. Tencent has also released training and LoRA fine-tuning code. It targets developers and hobbyists who want to generate video locally on consumer hardware.
