AI #194: Spy versus Guy — Claude Fable 5.2, Jensen Huang Scandal, and METR's AI R&D Acceleration Report

The AI #194 newsletter covers the release of Claude Fable 5.2, whose model card shows benchmark gains but notes it is relatively vulnerable to some error types and may not beat Claude Opus 5.5 as a daily driver. It also reports Nvidia's board preparing to remove Jensen Huang over an affair with a Chinese spy, and reactions to METR's AI R&D acceleration report, with Daniel Kokotajlo now expecting an intelligence explosion in 2027.
