The ablation is a rank-2 update applied to the attn.o_proj, mlp.down_proj projections of layers 30-64, solved in closed form rather than by gradient descent.

Abliteration parameters

Performance

Metric	This model	Original model (TeichAI/Qwen3.8-27B-Fable-Distill)
KL divergence	0.1004	0 (by definition)
Refusals	5/100	91/100

KL divergence is measured against the original model on held-out harmless prompts (mlabonne/harmless_alpaca), and refusals are counted over 100 harmful prompts (mlabonne/harmful_behaviors, test[:100]).
