	# MiniMax-M2.7-RotorQuant-MLX-5bit

	MLX 5-bit quantized variant of [MiniMaxAI/MiniMax-M2.7](https://huggingface.co/MiniMaxAI/MiniMax-M2.7) with RotorQuant KV-cache compression, optimized for Apple Silicon.

	## Overview

	MiniMax-M2.7 is a massive 256-expert Mixture-of-Experts (MoE) model with 8 experts active per token, totaling approximately 456 billion parameters. This variant combines 5-bit MLX weight quantization with RotorQuant KV-cache quantization for deployment on Apple Silicon hardware.

	RotorQuant applies a learned Hadamard rotation matrix to keys and values before quantization, smoothing the activation distribution for better quality retention. The 5-bit weight quantization offers a strong balance between quality and memory footprint.

	\| Property \| Value \|
	\|---\|---\|
	\| Architecture \| MoE (256 experts, 8 active/token) \|
	\| Total Parameters \| ~456B \|
	\| Layers \| 62 \|
	\| Hidden Size \| 3072 \|
	\| Attention Heads \| 48 \|
	\| Weight Quantization \| 5-bit (MLX) \|
	\| KV-Cache Quantization \| RotorQuant \|
	\| Estimated Size \| ~280 GB \|
	\| Base Model \| MiniMaxAI/MiniMax-M2.7 \|

	## Quickstart

	```bash
	pip install mlx-lm
	```

	```python
	from mlx_lm import load, generate

	model, tokenizer = load("majentik/MiniMax-M2.7-RotorQuant-MLX-5bit")

	prompt = "What is a Comprehensive Geriatric Assessment?"
	messages = [{"role": "user", "content": prompt}]
	text = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)

	response = generate(
	model,
	tokenizer,
	prompt=text,
	max_tokens=512,
	)
	print(response)
	```

	## RotorQuant vs TurboQuant

	\| Feature \| RotorQuant \| TurboQuant \|
	\|---\|---\|---\|
	\| Technique \| Rotation-based KV quantization (Hadamard transform) \| Asymmetric per-channel KV quantization \|
	\| Throughput \| Slightly lower throughput (rotation overhead) \| Higher throughput, lower latency \|
	\| Quality \| Better quality preservation at low bit-widths \| Good quality preservation \|
	\| Best For \| Quality-sensitive tasks, research \| High-throughput serving, long contexts \|

	## Memory Estimates (Apple Silicon)

	\| Variant \| Estimated Size \| Minimum Unified Memory \|
	\|---\|---\|---\|
	\| MLX 8-bit \| ~456 GB \| 512 GB (Mac Studio M2/M3/M4 Ultra) \|
	\| MLX 5-bit \| ~280 GB \| 384 GB \|
	\| MLX 4-bit \| ~225 GB \| 256 GB \|
	\| MLX 3-bit \| ~170 GB \| 192 GB \|
	\| MLX 2-bit \| ~110 GB \| 128 GB \|

	> Note: 5-bit quantization requires Apple Silicon with 384 GB+ unified memory, such as a Mac Studio with M2/M3/M4 Ultra.
