SE-Bench: Benchmarking Self-Evolution with Knowledge Internalization

Jiarui Yuan, Tailin Jin, Weize Chen +1

True self-evolution requires agents to act as lifelong learners that internalize novel experiences to solve future problems. However, rigorously measuring this foundational capabil…

Process Reinforcement through Implicit Rewards

Ganqu Cui, Lifan Yuan, Zefan Wang +22

Dense process rewards have proven a more effective alternative to the sparse outcome-level rewards in the inference-time scaling of large language models (LLMs), particularly in ta…

The Overthinker's DIET: Cutting Token Calories with DIfficulty-AwarE Training

Weize Chen, Jiarui Yuan, Tailin Jin +4

Recent large language models (LLMs) exhibit impressive reasoning but often over-think, generating excessively long responses that hinder efficiency. We introduce DIET ( DIfficulty-…

Optima: Optimizing Effectiveness and Efficiency for LLM-Based Multi-Agent System

Weize Chen, Jiarui Yuan, Chen Qian +3

Large Language Model (LLM) based multi-agent systems (MAS) show remarkable potential in collaborative problem-solving, yet they still face critical challenges: low communication ef…
