Abliteration is a mechanistic interpretability technique that identifies and orthogonalizes the "refusal direction" in a model's activation space, surgically removing refusal behavior without full fine-tuning.

Abliteration Parameters

Parameter	Value
Base model	`/Users/hong/mlx-convert/models/gemma-4-31b-it-8bit`
Ablation method	`projection`
Refusal vector policy	`per-layer`
Refusal direction method	`difference`
Ablation strength	`2.0`
Probed layers	`5,11,17,23,29,35,41,47,53,59`

Attention only	`True`
Excluded modules	`none`

This model uses a Mixture-of-Experts (MoE) architecture. Abliteration targets only the attention projection weights (q/k/v/o_proj) to preserve expert routing quality.
