dealignai/Qwen3.5-VL-122B-A10B-JANG_4K-CRACK

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. LM Studio, Ollama, and other apps do not support JANG yet.

MLX Studio — the only app that natively supports JANG models

Qwen 3.5 VL 122B-A10B — JANG_4K + CRACK

JANG K-quant · CRACK abliterated · No guardrails · VLM · 62 GB

What Is This?

This is Qwen 3.5 122B-A10B — a 122B parameter Mixture-of-Experts model with 256 experts (8 active per token), hybrid GatedDeltaNet SSM + full attention architecture, and built-in vision-language capabilities.

It has been:

1. JANG quantized — JANG_4K profile (K-quant: 8-bit attention, 4-bit embeddings, 3-bit experts) — 62 GB
2. CRACK abliterated — permanent weight-level removal of safety refusal behavior

JANG_4K is a budget-neutral K-quant: same total size as MLX uniform 4-bit, but with attention weights at 8-bit for maximum coherence. On MoE models where attention is <5% of parameters, this precision boost is nearly free.

Architecture	Qwen 3.5 MoE — 122B total, 10B active, 256 experts
Quantization	JANG_4K (8/4/3-bit K-quant) — 62 GB
Abliteration	CRACK — permanent weight modification
Vision	Built-in VLM (333 vision encoder tensors)
Thinking	Supports enable_thinking ON/OFF
Speed	~45 tok/s (M4 Ultra 256GB)
Fits on	96 GB+ Macs

Key takeaway: CRACK surgery costs 4.5 MMLU points vs unmodified JANG_4K (81.5% vs 86%). The JANG_4K base matches MLX 4-bit (86% vs 85%) at the same size with smarter bit allocation.

Also available: JANG_2S CRACK (35 GB)

Smaller model for 48 GB+ Macs — 77.5% MMLU, 91.2% HarmBench.

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. No custom model files, no runtime hooks — permanent and runs at full native speed.
