This is a decensored version of TeichAI/Qwen3.8-27B-Fable-Distill, made using Heretic v1.2.0 with the Arbitrary-Rank Ablation (ARA) method

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.

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]).
