# MiniMax-M2.7 JANG_3L

**MiniMax M2.7 228B MoE — 3.08-bit mixed precision, 89 GB**

Best balance of quality and size — fits on 128 GB+ Macs.
</div>

> **Recommended: Run in [MLX Studio](https://mlxstudio.com)** for best experience including thinking mode support and optimized MoE inference.

## Important Settings

MiniMax M2.7 is an always-reasoning model. It thinks before answering on every prompt.

| Setting | Value | Notes |
|---------|-------|-------|
| Temperature | **1.0** | REQUIRED — greedy/temp=0 causes infinite thinking loops |
| Top P | 0.95 | |
| Top K | 40 | |
| Repetition Penalty | 1.1 | Optional, helps prevent loops |

## Model Details

| Metric | Value |
|--------|-------|
| Source | `MiniMaxAI/MiniMax-M2.7` (FP8 E4M3) |
| Architecture | MoE (256 experts, top-8 active), GQA (48 heads / 8 KV), partial RoPE |
| Total Parameters | 228.7B |
| Active Parameters | ~1.4B per token |
| Profile | JANG_3L (CRITICAL=8-bit, IMPORTANT=4-bit, COMPRESS=3-bit) |
| Actual avg bits | 3.08 |
| Model size | 89 GB |
| Format | JANG v2 (MLX-native safetensors, instant load) |
| group_size | 128 (speed-optimized for 256 experts) |
| Routing | Sigmoid + bias correction (not softmax) |
| QK-norm | Full vector RMSNorm |
| Context | 192K tokens |

## JANG_3L Bit Allocation

| Tier | Components | Bits |
|------|-----------|------|
| CRITICAL | Attention (Q/K/V/O), lm_head | 8 |
| IMPORTANT | Embeddings | 4 |
| COMPRESS | Expert MLP (w1/w2/w3) — 98%+ of params | 3 |
| Passthrough | MoE router/gate (float16), norms, QK-norms | 16 |

JANG protects routing and attention at full precision while compressing the 256 expert MLPs — where MoE models are most tolerant of quantization. The router is kept at float16 (no quantization) for maximum routing precision.

## MMLU Benchmarks (200q, 10 subjects, reasoning ON)

*Coming soon — benchmarks in progress.*

## Why JANG for MiniMax

Standard MLX quantization on MiniMax produces **completely broken output at ALL bit levels** (~25% MMLU = random guessing). JANG's mixed-precision approach is the **only working quantized MiniMax on Apple Silicon**.

On M2.5, JANG_2L achieved **74% MMLU** vs MLX's 25% (random). M2.7 results pending.

## All Quantizations

| Model | Profile | Size | Avg Bits |
|-------|---------|------|----------|
| [JANG_2L](https://huggingface.co/JANGQ-AI/MiniMax-M2.7-JANG_2L) | (8, 6, 2) | 63 GB | 2.10 |
| [JANG_3L](https://huggingface.co/JANGQ-AI/MiniMax-M2.7-JANG_3L) | (8, 4, 3) | 89 GB | 3.08 |
| [JANG_4M](https://huggingface.co/JANGQ-AI/MiniMax-M2.7-JANG_4M) | (8, 4, 4) | 115 GB | 4.06 |
| [JANG_6M](https://huggingface.co/JANGQ-AI/MiniMax-M2.7-JANG_6M) | (8, 6, 6) | 167 GB | 6.03 |

## Requirements

- Apple Silicon Mac with 128 GB unified memory
- MLX framework
- [MLX Studio](https://mlxstudio.com) recommended

## Usage

```python
from jang_tools.loader import load_jang_model
from mlx_lm import generate
from mlx_lm.sample_utils import make_sampler

model, tokenizer = load_jang_model("JANGQ-AI/MiniMax-M2.7-JANG_3L")
sampler = make_sampler(temp=1.0, top_p=0.95)

prompt = tokenizer.apply_chat_template(
    [{"role": "user", "content": "What is photosynthesis?"}],
    tokenize=False, add_generation_prompt=True
)
output = generate(model, tokenizer, prompt=prompt, max_tokens=2048, sampler=sampler)
print(output)
```
