Hi everyone β€” for those on Mac: MiniMax-H3 can now be generated locally on Apple Silicon directly from ComfyUI.

Wild H3C is a ComfyUI custom node package that wraps antirez's h3.c Metal engine:

  • 🎬 H3 Text to Video and H3 Reference to Video (Ref2VA) nodes β€” canvas, duration, steps, presets, seed, first/last-frame anchors, up to 9 reference images + 1 reference audio
  • πŸ“ˆ Live per-phase progress in the UI and clean cancellation
  • πŸ”Œ Standard VIDEO output, plugs straight into SaveVideo
  • πŸ’Ύ Works with an existing MiniMax-H3 snapshot (just point the node at it) or a fresh download β€” both paths are documented

Tested on an M-series MacBook Pro with 128 GB unified memory (512Γ—512, 4 steps β‰ˆ 32 s warm). Note that the MiniMax H3 Community License applies to the weights. Feedback, issues and PRs welcome!
