A new research paper explores how context compression techniques in language models might inadvertently weaken their refusal alignment. The study found that while compression methods can effectively reduce inference costs by creating compact representations, they systematically degrade the models' ability to refuse harmful or inappropriate instructions. This degradation occurs even when the semantic content of the input is well-preserved. The researchers identified that compression attenuates specific activations related to refusal behavior and proposed a lightweight intervention called Memory Steering to restore these refusal rates without requiring model retraining.
