Fetch-then-Explore: Decoupling Selection from Extraction over a Persistent Workspace for Search Agents

Qi Liu, Yiqun Chen, Zidan Chen +6

Search agents now answer questions that take dozens of searches to settle, yet how such an agent reads a page has drawn far less attention than how it finds one. Nearly all of them…

Reinforcing Chain-of-Thought Reasoning with Self-Evolving Rubrics

Leheng Sheng, Wenchang Ma, Ruixin Hong +3

Despite chain-of-thought (CoT) playing crucial roles in LLM reasoning, directly rewarding it is difficult: training a reward model demands heavy human labeling efforts, and static…
