Researchers have developed a new framework to understand why jailbreaks are successful in diffusion-based large language models (dLLMs). They propose that safety alignment can be viewed as shaping the energy landscape of the model, where harmful queries are directed away from safe outputs by an energy barrier. Jailbreak attacks work by either masking the query's harmful intent initially or by intervening during the generation process to force the path across this barrier. The study introduces three training-free detection signals based on initial safety disposition and trajectory velocity, which were tested on several dLLMs including LLaDA-8B, LLaDA 1.5, Dream-7B, and LLaDA-MoE-7B, confirming their effectiveness.
