Asked:“Which AI researchers moved between frontier labs since 2025? For each move list the researcher, the lab they left, where they went and the month.”
25 publicly reported researcher moves between frontier AI labs, January 2025 through 4 September 2026, drawn from 10 independent news hosts. This is a census of documented public reports, not a provably complete registry of every move; the largest single article supports 7 of the 25 rows.
Ribbon width = number of reported moves along that corridor. Left: lab left. Right: lab joined. Hover a ribbon for the researchers behind it.
| Month | Researcher | Left | Joined | Role | Source |

Documented public-reporting census of 25 researcher moves between frontier AI labs (OpenAI, Anthropic, Google DeepMind, Meta and Meta Superintelligence Labs, Thinking Machines Lab, and peers), January 2025 – 4 September 2026. Month is when the move was publicly reported, not the first working day. 10 independent source hosts; the largest single URL backs 7 of 25 rows. Meta and Meta Superintelligence Labs are kept distinct where sources support it. Product and policy staff, and moves from universities or non-AI employers, are excluded.
