This repository contains the GGUF quantized files for wangzhang/Qwen3.5-122B-A10B-abliterix.

Quant Type Size Description
IQ4_NL 77 GB Mixed Precision for Better Quality

Highlights

Metric Value
Refusal rate 1/200 (0.5%)
KL divergence 0.0115
Optimization trials 25

The largest abliterated Qwen3.5 model. Only 1 out of 200 test prompts triggered a refusal — a 0.5% refusal rate with near-zero model degradation.

How It Works

Abliterix removes safety-refusal behavior while preserving model capabilities:

  1. Refusal direction extraction — 800 harmful + 800 benign prompts reveal per-layer refusal activation patterns
  2. Orthogonal projection — isolates the refusal signal by projecting out components aligned with normal responses, reducing refusals by 67% vs. raw abliteration
  3. LoRA-based abliteration — rank-1 modifications to attention and MLP weights, captured as lightweight adapters (not destructive edits)
  4. Bayesian optimization — Optuna TPE searches kernel shape, fractional direction index, and per-component strength across 25 trials to find the Pareto-optimal balance of low refusals and low KL divergence
