Study finds smaller AI models outperform large ones in drug discovery predictions

A new paper challenges the assumption that larger AI models are always superior in drug discovery. Researchers found that classical machine learning models and graph neural networks often outperform larger, general-purpose models on molecular property and activity prediction tasks. While large models may offer benefits in areas like zero-shot reasoning, their predictive advantage is not universal and depends heavily on specific task alignments. AI
