HunyuanVideo-1.5

Why we included this project

HunyuanVideo-1.5 is for creators and developers who want serious text-to-video and image-to-video generation without renting a rack of GPUs. The model is 8.3B parameters and designed to run on consumer hardware; Tencent pitches it as usable on a single 4090, which gets individual creators generating short clips instead of paying per minute on cloud APIs. The repo ships working inference scripts and plugs into ComfyUI and Diffusers for day-to-day work, with a separate lightweight LightX2V runtime if you need something leaner. It also includes training and LoRA fine-tuning code built around the Muon optimizer, so teams can adapt the base model to their own style or domain rather than taking it as-is. When iteration speed matters more than maximum quality, the step-distilled checkpoints and caching options speed things up noticeably.
