Anthropic Reveals AI Research Bottleneck: Agents Excel at Engineering, Not Discovery

Anthropic's new paper shows frontier coding agents surpass all 20 scientific benchmarks, but gains stem from hyperparameter tuning and architecture changes rather than genuine scientific innovation; the study identifies three pathologies—novelty misjudgment, resource waste, exploration collapse—and demonstrates that adding research-process scaffolding doubles performance, with one task achieving 91% improvement through physics-informed reasoning.
