Claude-shaped science

AnnouncementResearchOct 1, 2026

Anthropic published a guest post by Prof. Matthew Schwartz describing BootLoops, an open-source toolkit that acts as a harness for Claude on quantitative science problems. Schwartz reports that Claude Opus 4.5 performed like a strong graduate student at 20 times the speed, but required heavy correction. By targeting "Claude-shaped" problems suited to the model's strengths, BootLoops found technically correct connections across ecology, population genetics, and other fields, which Schwartz refined with domain experts.
