MiniMax-M2.7-JANG_2L-CRACK

dealignai/MiniMax-M2.7-JANG_2L-CRACK

MiniMax-M2.7-JANG_2L-CRACK is a text generation model from dealignai. Use it when you need the model to write or continue text. It is set up for mlx. The card lists the license as other.

Important: This model uses the JANG quantization format -- the GGUF equivalent for MLX on Apple Silicon. Currently only supported by MLX Studio and the jang-tools Python package. Follow @dealignai for new releases.

MiniMax M2.7 -- JANG_2L + CRACK

JANG mixed-precision | CRACK abliterated | Reasoning-only | 63 GB

</div>

What Is This?

This is MiniMax M2.7 -- a 230B parameter Mixture-of-Experts reasoning model with 256 experts (8 active per token), all standard attention, and always-on chain-of-thought reasoning.

It has been:

JANG quantized -- JANG_2L profile (8-bit attention, 6-bit embeddings, 2-bit experts) -- 63 GB
CRACK abliterated -- permanent weight-level removal of safety refusal


Architecture	MiniMax M2.7 MoE -- 230B total, ~10B active, 256 experts
Quantization	JANG_2L (8/6/2-bit mixed) -- 63 GB
Abliteration	CRACK abliterated
MMLU-200	84.0% (base: 88.0%, delta: -4.0%)
HarmBench-320	83.4% overall, 93.7% excluding copyright
Compliance	8/8 quick test
Reasoning	Always ON (chain-of-thought)
Speed	~47 tok/s (M4 Ultra 256 GB)
Fits on	96 GB+ Macs

Note on copyright: M2.7's base model has strong copyright training and refuses to reproduce copyrighted books/lyrics regardless of abliteration. This is a base model limitation, not a surgery result.

vs MLX Uniform Quantization

MLX uniform quantization is completely broken on MiniMax at ALL bit levels (~25% MMLU = random chance). JANG is the only working quantization format for this architecture.

Install & Usage

pip install "jang[mlx]"

from jang_tools import load_for_inference
from mlx_lm import generate
from mlx_lm.sample_utils import make_sampler

model, tokenizer = load_for_inference("dealignai/MiniMax-M2.7-JANG_2L-CRACK")
sampler = make_sampler(temp=1.0)  # MiniMax requires temp=1.0 for chat

messages = [{"role": "user", "content": "Your prompt here"}]
prompt = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True, tokenize=False)

response = generate(model, tokenizer, prompt=prompt, max_tokens=4000, sampler=sampler)
print(response)

Note: M2.7 is a reasoning-only model -- it always generates a <think> chain before answering. Use max_tokens=4000+ for complex questions. For chat, use temperature=1.0 (greedy causes infinite loops).

About JANG

JANG (Jang Adaptive N-bit Grading) is a mixed-precision quantization format for Apple Silicon -- the GGUF equivalent for MLX. Classifies tensors into sensitivity tiers and assigns bits accordingly.

About CRACK

CRACK (Controlled Refusal Ablation via Calibrated Knockouts) removes safety alignment from LLMs at the weight level, achieving compliance while preserving reasoning quality.
