TL;DR: This paper seeks to improve our understanding on how jailbreaks work by investigating latent space dynamics of different jailbreak types.
Abstract: Conversational Large Language Models are trained to refuse to answer harmful questions. However, emergent jailbreaking techniques can still elicit unsafe outputs, presenting an ongoing challenge for model alignment. To better understand how different jailbreak types circumvent safeguards, this paper analyses model activations on different jailbreak inputs. We find that it is possible to extract a jailbreak vector from a single class of jailbreaks that works to mitigate jailbreak effectiveness from other classes. This may indicate that different kinds of effective jailbreaks operate via similar internal mechanisms. We investigate a potential common mechanism of harmfulness feature suppression, and provide evidence for its existence by looking at the harmfulness vector component. These findings offer actionable insights for developing more robust jailbreak countermeasures and lay the groundwork for a deeper, mechanistic understanding of jailbreak dynamics in language models.
