Mistral-Small-4-Uncensored-JANG_2L

⚠️ MLX Studio ONLY. This model uses the JANG quantization format — the GGUF equivalent for MLX on Apple Silicon. NOT compatible with LM Studio, Ollama, oMLX, or Inferencer. Requires MLX Studio or pip install "jang[mlx]".

What Is This?

The first uncensored version of Mistral Small 4 (119B) for Apple Silicon. A 119B parameter MoE model with Multi-head Latent Attention (MLA), 128 experts, and Pixtral vision — with all safety guardrails permanently removed at the weight level.

Runs ONLY in MLX Studio or via jang-tools Python package. JANG is the GGUF equivalent for MLX — it is NOT compatible with GGUF-based tools.

It has been:

1. JANG quantized — JANG_2L profile (8-bit attention, 6-bit important, 2-bit experts) — 37 GB
2. CRACK abliterated — permanent weight-level removal of safety refusal

Also see: JANG_4M version — 64 GB, 95.3% HarmBench, 8/8 compliance (fits on 96 GB Macs)

HarmBench Results

307/320 (95.9%)

Requirements

This model REQUIRES MLX Studio or jang-tools. It will NOT work with:

• ❌ LM Studio
• ❌ Ollama
• ❌ oMLX
• ❌ Inferencer
• ❌ Any GGUF-based tool

HarmBench Results

307/320 (95.9%)

CRACK vs Base

Surgery reduced no-think MMLU by only 1.4% — the 2-bit quantization is the bottleneck, not CRACK.

MMLU Results (with reasoning recovery)

187/208 (89.9%) — no-think 137/208 (65.9%) + reasoning recovered 50

Install

pip install "jang[mlx]"

Usage

from jang_tools.loader import load_jang_model
from mlx_lm import generate

model, tokenizer = load_jang_model("dealignai/Mistral-Small-4-Uncensored-JANG_2L")

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=2000)
print(response)

Reasoning Mode

Reasoning is OFF by default. To enable step-by-step thinking:

prompt = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True,
    tokenize=False, reasoning_effort="high")

The model reasons inside [THINK]...[/THINK] tags before answering.

About JANG

JANG (Jang Adaptive N-bit Grading) is a mixed-precision quantization format designed specifically for Apple Silicon — the GGUF equivalent for MLX. It classifies every weight tensor by sensitivity and assigns optimal bit-widths, achieving better quality-per-bit than uniform quantization.

About CRACK

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