Antirez/h3.c: MiniMax H3 inference engine for Mac computers
h3-metal Native MiniMax-H3 inference for Apple Silicon. The project is being built as a sequence of working vertical slices: deterministic host/model metadata first, then portable Metal block parity, prompt encoding, prompt-to-video/audio, and first/last-frame conditioning and then ordered references. Prompt-to-video/audio, first/last-frame conditioning, and ordered Ref2VA image/video/audio references work end to end.

h3-metal Native MiniMax-H3 inference for Apple Silicon. The project is being built as a sequence of working vertical slices: deterministic host/model metadata first, then portable Metal block parity, prompt encoding, prompt-to-video/audio, and first/last-frame conditioning and then ordered references. Prompt-to-video/audio, first/last-frame conditioning, and ordered Ref2VA image/video/audio references work end to end. The current work is incremental H3-specific Metal performance and memory optimization on M3 Max and M5 Max. Tutorial 1. Build and inspect the model The examples assume that the Hugging Face snapshot is in ./MiniMax-H3 and that FFmpeg and FFprobe are available on PATH.
