# FastH3-Omni
[FastVideo's 8-step FastH3-Omni](https://huggingface.co/FastVideo/FastVideo-FastH3-Omni-8-Step-V1) student of MiniMax-H3 on ZeroGPU: ordered image, video and audio references plus
a prompt become a short clip with a matching soundtrack. Runs the FP8 W8A8 export (`FastVideo/FastH3-Omni-FP8`)
with FastVideo's Triton tile-64 block-sparse attention, and restores its compiled kernels from
`multimodalart/fasth3-omni-kernel-cache` at startup so the first call doesn't JIT-compile.
The prompt composer is a custom `gr.HTML` component (`composer.html` / `composer.css` / `composer.js`): references
get `<Picture n>` / `<Video n>` / `<Audio n>` tags as they are added, and the prompt is either assembled by the
six-section H3 builder or written by hand with those tags. "Upsample" rewrites it through
`hugging-apps/minimax-h3-prompt-rewriter`.
FastVideo is installed from a wheel of `hao-ai-lab/FastVideo@376e445f` whose unused `gradio==5.32.0` pin is relaxed,
so the Space runs Gradio 6.
