Closed-loop Auto Research for Molecular Property Prediction: Discovering and Certifying Generalizable Improvements

Researchers demonstrate that closed-loop automated machine learning systems can discover generalizable improvements in molecular property prediction by having language-model agents modify features, models, and acquire external evidence. Testing across 36 molecular endpoints reveals that while some improvements validate strongly, they don't consistently transfer to held-out test sets, highlighting critical challenges in ensuring reproducibility of AI-driven research discoveries.

When No Benchmark Exists: Validating Comparative LLM Safety Scoring Without Ground-Truth Labels

Researchers propose a framework for comparing language models on safety without labeled benchmark data, introducing SimpleAudit as a validation tool that uses controlled contrasts and variance analysis to establish model safety rankings. The study demonstrates that comparative safety scores are inherently context-dependent, requiring detailed reporting of methods rather than single rankings.
