HunyuanVideo: A Systematic Framework For Large Video Generation Model
Mochi 1 is an open-source video project by genmoai (genmoai/mochi on GitHub). It has 3,755 GitHub stars and 494 forks, is released under the Apache-2.0 license, and was last updated on GitHub on 22 October 2026.
Mochi 1 — Genmo's open state-of-the-art video generation model, with high-fidelity motion and strong prompt adherence, Apache-2.0
Clone, create a Python 3.11 virtual environment with uv, activate it, and sync the locked dependencies.
Download the model and VAE into a local weights directory with the bundled script (or from Hugging Face).
Run generation, and make sure ffmpeg is installed — it turns the model outputs into viewable videos.
High-fidelity motion and strong prompt adherence, released openly instead of behind an API.
Code and weights under Apache-2.0, so the model can be used and built on freely.
Fine-tune Mochi 1 on your own style or subject with the bundled fine-tuner.
Native ComfyUI support lets smaller GPUs run the model where the full pipeline cannot.
The README install route with uv (Python 3.11+).

Yes — Apache-2.0 licensed, including the weights.
The full pipeline wants a strong GPU, but consumer-GPU support exists natively in ComfyUI, and the playground lets you try it free first.
Python 3.11+, uv, the model weights, and ffmpeg for turning outputs into videos.
Clone, uv sync the locked environment, download the weights, and generate — or try the Genmo playground first.
