Large Language Model Agents Are Not Always Faithful Self-Evolvers

Weixiang Zhao, Yingshuo Wang, Yichen Zhang +5

Self-evolving large language model (LLM) agents continually improve by accumulating and reusing past experience, yet it remains unclear whether they faithfully rely on that experie…

When Less Language is More: Language-Reasoning Disentanglement Makes LLMs Better Multilingual Reasoners

Weixiang Zhao, Jiahe Guo, Yang Deng +9

Multilingual reasoning remains a significant challenge for large language models (LLMs), with performance disproportionately favoring high-resource languages. Drawing inspiration f…
