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-refusal tasks also. In this post, we explore Dynamic Abliteration using Multi-Layer Steering with Engram.
