MiniMax-H3-FL2VA-MLX-Serve-8bit

MiniMax-H3 FL2VA — MLX-Serve 8-bit

8-bit affine (group size 64) conversion of MiniMax-H3's FL2VA checkpoint for mlx-serve, running natively on Apple Silicon. Text-to-audio-video: the DiT denoises video and stereo audio jointly in one packed sequence.

Self-contained: weights, both VAEs and the tokenizer in one directory. Upstream splits these across Comfy-Org/MiniMax-H3 (weights, no tokenizer) and MiniMaxAI/MiniMax-H3 (tokenizer).

Quantized: the DiT and text-encoder matmul weights. Kept dense: gathered embedding tables, the checkpoint's fp32 islands (patch projections, output heads, time embedder) and both VAEs.

Note that quantization here buys FOOTPRINT, not speed — the workload is compute-bound at roughly 192,000 FLOPs per weight byte.

Modifications

These are MODIFIED files. The transformer and text encoder are quantized to 8-bit; see MODIFICATIONS.md for the full list. The VAEs and tokenizer are unmodified copies.
