New methods probe and break LLM safety representations

Researchers have developed new methods to probe and potentially break the safety mechanisms within large language models. By analyzing how models refuse certain prompts, they identified that safety representations are distributed across the model's layers rather than being localized to a single point. Their new technique, Activation-Guided GCG, directly targets these internal refusal directions, proving more effective than previous methods. Additionally, a continuous relaxation technique called Soft-GCG significantly speeds up optimization while improving attack success rates, though larger, more extensively trained models show greater resistance.

    Optimizing Against Safety Representations: Activation-Guided Adversarial Suffixes and the Geometry of Refusal

    Behavioral alignment in large language models often masks fragile internal safety representations. Recent work suggests that refusal behavior is mediated by low-dimensional directions in activation space. This raises questions about how such representations are structured, locali…
