AgentProcessBench: Diagnosing Step-Level Process Quality in Tool-Using Agents

Shengda Fan, Xuyan Ye, Yupeng Huo +9

While Large Language Models (LLMs) have evolved into tool-using agents, they remain brittle in long-horizon interactions. Unlike mathematical reasoning where errors are often recti…

Rethinking On-Policy Distillation of Large Language Models: Phenomenology, Mechanism, and Recipe

Yaxuan Li, Yuxin Zuo, Bingxiang He +8

On-policy distillation (OPD) has become a core technique in the post-training of large language models, yet its training dynamics remain poorly understood. This paper provides a sy…

Learning beyond Teacher: Generalized On-Policy Distillation with Reward Extrapolation

Wenkai Yang, Weijie Liu, Ruobing Xie +3

On-policy distillation (OPD), which aligns the student with the teacher's logit distribution on student-generated trajectories, has demonstrated strong empirical gains in improving…

LaSeR: Reinforcement Learning with Last-Token Self-Rewarding

Wenkai Yang, Weijie Liu, Ruobing Xie +4

Reinforcement Learning with Verifiable Rewards (RLVR) has recently emerged as a core paradigm for enhancing the reasoning capabilities of Large Language Models (LLMs). To address t…
