Anthropic researcher Joe Benton departs to join AI evaluator METR
Joe Benton, a researcher on Anthropic's frontier risk evaluation team, announced that he left Anthropic last week to join METR, a third-party AI safety evaluation organization, working on embedded assessment of AI risks. He spent about 1.5 years at Anthropic, said his experience and treatment there were good, but had long planned to leave if a higher-impact opportunity arose.
Confirmed
- Joe Benton left Anthropic last week and joined METR
- He worked at Anthropic for about 1.5 years on AI risk and evaluation
- His new role focuses on embedded assessment of AI risks
- He spoke positively of Anthropic; the move was driven by pursuing greater impact
Why it matters
- METR is independent of frontier labs, and talent flowing from a leading lab to an evaluator strengthens external independent evaluation capacity
- @AndyMasley, citing METR's Max Nadeau, argued safety-evaluation talent is accelerating toward METR—a talent-flow trend worth watching
