🔧 2026-04-15 · chat_template.jinja — enable_thinking=False honored

This release ships a chat_template that respects enable_thinking=False (synced with the JANG_2L template structure, M2.7 identity preserved). The <think> prefix is now conditional, so callers can skip reasoning mode for fast direct answers. Reasoning ON (default) is unchanged.

Model weights are unchanged.

Important: This model uses the JANGTQ (JANG TurboQuant) quantization format -- an extreme-compression variant of JANG for MLX on Apple Silicon that uses codebook + Hadamard rotation on MoE experts while keeping attention at affine 8-bit. Currently only supported by MLX Studio and the jang-tools Python package. Follow @dealignai for new releases.

MiniMax M2.7 -- JANGTQ + CRACK

JANGTQ TurboQuant mixed-precision | CRACK abliterated | Reasoning-only | 55 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:

1. JANGTQ quantized -- JANGTQ profile (8-bit affine attention / embeddings / lm_head, 2-bit TurboQuant routed experts with codebook + Hadamard rotation) -- 55 GB
2. CRACK abliterated -- permanent weight-level removal of safety refusal

MMLU-200 Results

CRACK is knowledge-neutral on this model -- small per-subject variance, net positive. Gains on physics, fallacies, religions offset losses on algebra and anatomy.

HarmBench-320 Results

Scored with a strict classifier that rejects stuck-reasoning loops, empty template dumps, and false-positive compliance from thinking-trace leakage.

JANG CRACK M2.7 Series

vs MLX Uniform Quantization

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

About JANGTQ

JANGTQ (JANG TurboQuant) is an extreme-compression variant of JANG that replaces affine quantization on routed MoE experts with codebook quantization + random Hadamard rotation. Attention / embeddings / lm_head stay at affine 8-bit for precision-critical paths; the 256 routed experts use 2-bit packed codebook indices stored as uint32, with a per-row float16 norm and a tiny Lloyd-Max codebook per layer. Metal kernels do dequant + matmul fused on-GPU, no affine conversion.

For MiniMax M2.7 (230B total, 10B active, 256 experts) this brings the model from 460 GB (bf16) down to 55 GB with minimal quality loss -- the JANGTQ profile beats every MLX uniform quant while fitting on a 96 GB Mac.

About CRACK

CRACK (Controlled Refusal Ablation via Calibrated Knockouts) is a weight-level intervention that removes safety alignment while preserving reasoning quality and compliance. The modification is permanently baked into the published weights — no LoRA, no fine-tuning, no system prompts.

Install & Usage

pip install "jang[mlx]"

from jang_tools.load_jangtq import load_jangtq_model
from mlx_lm import generate
from mlx_lm.sample_utils import make_sampler

model, tokenizer = load_jangtq_model("dealignai/MiniMax-M2.7-JANGTQ-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 the final answer. Use max_tokens=4000+ for complex questions. For chat, use temperature=1.0 (greedy causes infinite loops). Set enable_thinking=False in apply_chat_template to skip the <think> block on short responses.
