Can AI agents conduct open-ended AI research? Early evidence from two case studies

via Arxiv 👤 Peter Kirgis, Sayash Kapoor, Andrew Schwartz et al. 📅 2026-07-29
⚡ Score: 7.7
"Forecasts of explosive AI progress hinge on AI agents automating AI research. But evidence on whether agents can carry out open-ended AI research is thin. Current evaluations either test agents on narrow, verifiable tasks, which excludes open-ended research, or submit AI-generated papers to blind pe..."
