$D^2$-Monitor: Dynamic Safety Monitoring for Diffusion LLMs via Hesitation Signals.

arXiv:2605.25893v2 Announce Type: replace Abstract: Despite the emergence of diffusion large language models (D-LLMs) as an alternative to autoregressive large language models (AR-LLMs), safety monitoring for D-LLMs remains largely unexplored. Unlike AR-LLMs,
