Block diffusion accelerates speculative decoding by drafting multiple tokens in one forward pass. However, each position predicts a marginal distribution without observing earlier proposed tokens, limiting draft quality and acceptance length. We identify a concrete failure, the \emph{repetition trap}, in which neighbor...

Code editing requires a model to decide where to make changes, generate the new content, and preserve everything else. We study how masked diffusion language models divide these responsibilities across four editing interfaces: whole-file rewriting, search-and-replace, locate-then-infill, and token-level editing. Experi...

RedEvoAgent is proposed, a black-box red-teaming agent that distills cross-case attack trajectories into a concise, human-readable attack skill that outperforms fixed and agentic baselines, improves tool efficiency, and transfers across attacker models and target execution harnesses.
