MiniMax-M2.5 REAP-29 — MLX 4-bit

MLX 4-bit quantized version of Akicou/MiniMax-M2-5-REAP-29 for efficient local inference on Apple Silicon.

Quantization: 4-bit (group size 64, affine mode; router gates at 8-bit)
Architecture: MiniMax M2.5 MoE — 62 layers, 180 experts (REAP-pruned from 256), 8 active per token
Context: 196K tokens
Size: ~85 GB
Pruning: 29% of experts removed via REAP (Router Expert Activation Pruning)

Usage

from mlx_lm import load, generate

model, tokenizer = load("shieldstackllc/MiniMax-M2.5-REAP-29-mlx-4bit")
response = generate(model, tokenizer, prompt="Hello!", verbose=True)

Or with vMLX for native macOS inference.

About

MiniMax-M2.5 is a large Mixture-of-Experts language model by MiniMax AI. This variant was pruned to 29% fewer experts by Akicou using REAP (Router Expert Activation Pruning), reducing model size and memory footprint while maintaining strong performance. MLX quantization by vMLX.

Also Available

MiniMax-M2.5-REAP-39 MLX 4-bit (~73 GB) — 39% pruned variant
MiniMax-M2.5-REAP-39 MLX 8-bit (~138 GB) — 39% pruned variant

Made for vMLX

This model was converted and optimized for vMLX — a free, open source macOS native MLX inference engine for Apple Silicon. Download vMLX to run this model locally with zero configuration.
