Thinking Hard, Not Smart: Reasoning Models Fail to Ration Test-Time Compute Across Questions

Chenrui Fan, Yize Cheng, Ming Li +3

Reasoning language models increasingly use test-time compute to improve performance, but existing evaluations typically study this compute one question at a time. Yet when multiple…

MORSE-500: A Programmatically Controllable Video Benchmark to Stress-Test Multimodal Reasoning

Zikui Cai, Andrew Wang, Anirudh Satheesh +10

Despite rapid advances in vision-language models (VLMs), current benchmarks for multimodal reasoning fall short in three key dimensions. First, they overwhelmingly rely on static i…
