About Mochi

Mochi is the GitHub repository for Mochi 1 preview, an open-source video generation model created by Genmo and released under a permissive Apache 2.0 license. The model is a 10 billion parameter diffusion model built on an Asymmetric Diffusion Transformer (AsymmDiT) architecture, described in the repository as state of the art with high-fidelity motion and strong prompt adherence in preliminary evaluation.

The repository provides installation instructions, weight downloads, a Gradio UI, a command-line demo, and a Python API for programmatic generation. A separate trainer supports LoRA fine-tuning on your own videos. Running the model requires downloading weights locally and installing FFMPEG to turn outputs into videos, and the repository states that fine-tuning can be done on one H100 or A100 80GB GPU.
