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-toolsPython package. Follow @dealignai for new releases.
MiniMax M2.7 -- JANG_2L + CRACK
JANG mixed-precision | CRACK abliterated | Reasoning-only | 63 GB
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

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. Usemax_tokens=4000+for complex questions. For chat, usetemperature=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.
