| # FastH3 Omni on Apple Silicon (MLX) — build + benchmark kit |
|
|
| FastH3 Omni (reference-conditioned video + audio) runs natively on Apple Silicon through FastVideo's MLX runtime |
| ([hao-ai-lab/FastVideo#2000](https://github.com/hao-ai-lab/FastVideo/pull/2000)). |
|
|
| This repository holds the kit, not the weights: |
|
|
| - `bench/prepare_model_dir.sh` builds the MLX model directory from the public releases |
| (`FastVideo/FastVideo-FastH3-Omni-8-Step-V1`, `FastVideo/FastH3-Omni-NVFP4-QAD`, `FastVideo/FastH3-NVFP4-VAE-Decoder`, |
| `lightx2v/LightVAE`) at pinned revisions: INT6 (default), INT8 or BF16 transformer, NVFP4 text-encoder cache, |
| FastH3 36L/8L decoders and the LightVAE Lite H3 reference encoder. It verifies every file against SHA-256. |
| - `bench/run_matrix.py` runs the FastH3 Omni reference workloads and writes a latency table. See `bench/README.md`. |
|
|
| Licenses: MiniMax-H3 Community License for the model weights; Qwen3-VL and LightVAE are Apache-2.0 (see `bench/licenses/`). |
