These speed-ups for the MiniMax-H3 pipelines keep the output bit-identical. Each one has a switch that is off by default: - FASTVIDEO_MINIMAX_H3_EXACT_KERNELS: Triton RoPE, AdaLN modulation, gated residual and SwiGLU kernels that round to bf16 at the same points as the eager ops. - FASTVIDEO_H3_VSA_HEADS_FIRST_TILE: VSA-H3 tiles are written directly in the heads-first layout of the kernel. - FASTVIDEO_H3_VAE_TILE_PARALLEL: VAE spatial tiles are split across the sequence-parallel ranks. - FASTVIDEO_H3_REF2VA_MEMO_ENTRIES: repeat reference encodes are reused. The example basic_fasth3_omniref_pdd.py --lossless-accel turns them all on. On GB200 with 4 GPUs, MiniMax-H3 text to video with audio (124 frames, 1344x768) gives bit-identical frames and audio with the first three switches on and off.

Automatic Deployment
Documentation is automatically built and deployed to GitHub Pages when changes are pushed to the main branch via the .github/workflows/infra-docs.yml workflow.
Update documentation dependencies
Edit requirements-mkdocs.in, then regenerate the pinned Linux/Python 3.12 lock file:
uv pip compile requirements-mkdocs.in \
-o requirements-mkdocs.txt \
--python-platform x86_64-manylinux_2_28 \
--python-version 3.12
