AI Research Agents Have Radically Different Styles—Leaderboards Reduce Them to One Blind Number
ChengleiSi · x · 2026-10-07
Two AI research agents tackle the same task with completely different personalities: Fable pushes you to try bigger things, while Astra suggests running a pilot first and validating every piece of evidence. In the real world these process nuances matter—they determine whether you're partnering with a rigorous scientist or a reckless gambler—yet leaderboards compress scientific exploration into a single blind number. The author argues that since the entire scientific journey is now recorded in logs, we can finally benchmark the research process itself.
