“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.”
39 publicly reported technical-researcher moves between frontier AI labs, January 2025 through October 2026, one row per sourced transition with the month of start where reported, otherwise the month of announcement. This is a best-effort census of public reporting — private or unreported moves may be absent.
| Researcher | Left | Joined | Month | Date basis | Source |

Method: 39 publicly reported technical-researcher moves between frontier AI labs, January 2025 – 29 October 2026, compiled from news reports, memos and researcher homepages across many independent hosts; no single source backs more than half the rows. Month is the reported start month where available, otherwise the public-announcement month; nothing more precise than a month is inferred. In the chart, internal-team and parent-company labels (Google vs Google DeepMind, ByteDance vs ByteDance Seed, Meta vs Meta Superintelligence Labs) are grouped as one lab family; the table keeps the source-backed labels. A few names appear in romanized and Chinese-script aliases from separate sources and are listed as sourced. This is a public-reporting census, not a complete HR roster.
