Right Answer, Wrong Tokens: Tail-Aware Credit Calibration for RLVR

Xiuyi Lou, Zicheng Xu, Yu-Neng Chuang +4

Although reinforcement learning (RL) improves the reasoning capabilities of large language models (LLMs), GRPO-style methods can suffer from a positive-credit contamination failure…

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…

Demystifying OPD: Length Inflation and Stabilization Strategies for Large Language Models

Feng Luo, Yu-Neng Chuang, Guanchu Wang +4

On-policy distillation (OPD) trains student models under their own induced distribution while leveraging supervision from stronger teachers. We identify a failure mode of OPD: as t…
