How Should Diffusion Language Models Edit Code?

Xijia Tao, Ziru Liu, Shansan Gong +7

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 re…

DynamicMem: A Long-Horizon Memory Benchmark in Real-World Settings

Wenya Xie, Shengming Zhou, Zelin Li +9

LLM agents increasingly act as personal assistants that must remember a user's profile over months: who they are (attributes), what they routinely do (habits), and what they prefer…

SoftSkill: Behavioral Compression for Contextual Adaptation

Xijia Tao, Yihua Teng, Xinyu Fu +6

Natural-language skills let agents reuse task knowledge, yet deploying a long Markdown document makes the model interpret that knowledge anew on every call. We ask whether the beha…
