MiniMax-M3-Coder-Small

🦖 Osaurus Exclusive — a compact JANG-quantized MiniMax-M3 coder (coding · agentic · multimodal) for Apple Silicon.

⚠️ Requires vMLX engine v1.5.67+. This is a JANG-format model (JANG affine + AWQ quant, REAP expert pruning, MiniMax-M3 MSA/Lightning-Indexer runtime). It will NOT load with transformers, vLLM, or generic MLX loaders — it runs on the vMLX engine (ships in Osaurus).

What is a JANG model?

JANG is vMLX's quantization + packing format: mixed-precision affine quant with per-projection bit widths + AWQ activation-aware scaling + REAP expert pruning, via a jang_config.json. Weights stay quantized in GPU memory and load through vMLX's JANG loader. The format + the M3 runtime are vMLX-specific, so it runs only on vMLX 1.5.67 or newer.

Highlights

Smallest M3 coder — ~84 GB (the compact Osaurus build).
REAP45: keep 70/128 routed experts (45% pruned).
All-2-bit routed experts + AWQ (gate/up 2-bit AWQ-scaled, down 2-bit); attention 8-bit, shared experts 6-bit, embeddings 6-bit, lm_head 8-bit, Lightning Indexer FP16.
Multimodal (vision) kept.
Calibration: Vera (agentic-coder) + GSM8K; "floor" recipe keeps the most-salient coding experts.

Run it

In Osaurus / vMLX 1.5.67+: pick this model, Start, then chat.
CLI: vmlx-engine serve OsaurusAI/MiniMax-M3-Coder-Small --reasoning-parser minimax_m3 --tool-call-parser minimax_m3
