Dynamic Abliteration: Non-Destructive Refusal Suppression via Engram Steering

Overview

When working with open-weight LLMs like Qwen, controlling refusal behavior on security, administrative, prompts typically requires fine-tuning or permanent weight update. Traditional weight abliteration technique neutralizes refusal directions by projecting weight matrices orthogonal to a refusal vector. However, this permanently alters base model weights and can degrade performance across non-ref...
