Evaluating Interactive Reasoning in Large Language Models: A Hierarchical Benchmark with Executable Games

Mingyuan Fan, Weiguang Han, Daixin Wang +3

We introduce a multi-turn interactive framework for reasoning evaluation that treats reasoning as active evidence acquisition and belief updating. Wherein, LLMs receive only the ta…

SRR-Judge: Step-Level Rating and Refinement for Enhancing Search-Integrated Reasoning in Search Agents

Chen Zhang, Kuicai Dong, Dexun Li +4

Recent deep search agents built on large reasoning models (LRMs) excel at complex question answering by iteratively planning, acting, and gathering evidence, a capability known as…

When Sharpening Becomes Collapse: Sampling Bias and Semantic Coupling in RL with Verifiable Rewards

Mingyuan Fan, Weiguang Han, Daixin Wang +3

Reinforcement Learning with Verifiable Rewards (RLVR) is a central paradigm for turning large language models (LLMs) into reliable problem solvers, especially in logic-heavy domain…

From Long to Short: LLMs Excel at Trimming Own Reasoning Chains

Wei Han, Geng Zhan, Sicheng Yu +2

O1/R1 style large reasoning models (LRMs) signal a substantial leap forward over conventional instruction-following LLMs. By applying test-time scaling to generate extended reasoni…
