Before the Action: Benchmarking LLMs on Prospective Hypothesis Discovery

Tianyun Zhong, Wangyi Jiang, Wei Wang +15

Large language models (LLMs) excel at answering pre-specified questions, yet their ability to navigate the open-ended, pre-conclusion stage of discovery remains largely unmeasured.…

MedPRMBench: A Fine-grained Benchmark for Process Reward Models in Medical Reasoning

Lingyan Wu, Xiang Zheng, Weiqi Zhai +5

Medical reasoning can reach a plausible answer while overlooking an unsafe or unsupported intermediate step. Process-Level Reward Models (PRMs) can verify such steps, yet existing…

ClinConsensus: A Physician-Calibrated Benchmark for Evaluating Clinical Rubric Coverage in Chinese Medical LLMs

Xiang Zheng, Han Li, Wenjie Luo +15

Open-ended medical LLM evaluation remains weakly grounded in physician-calibrated coverage of clinically relevant response criteria, especially in localized clinical settings. We i…

SKYLENAGE Technical Report: Mathematical Reasoning and Contest-Innovation Benchmarks for Multi-Level Math Evaluation

Hu Wei, Ze Xu, Boyu Yang +15

Large language models (LLMs) now perform strongly on many public math suites, yet frontier separation within mathematics increasingly suffers from ceiling effects. We present two c…
