Test-Time Scaling in Reasoning Models Is Not Effective for Knowledge-Intensive Tasks Yet
Overview
Paper Summary
This study tested 12 large language models and found that increasing their "thinking time" did not reduce factual errors (hallucinations) and sometimes even made them worse. The models often just chose not to answer hard questions rather than actually getting better at reasoning.

Rating Explanation
This is a well-conducted study with a clear methodology and important findings about the limitations of current test-time scaling methods. However, the limited benchmark scope and lack of proposed solutions prevent a higher rating.
