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…

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-…
