Meta pulled 22 frontier researchers in 20 months — 17 of them in one June–July surge

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”

A web scan corroborated 55 reported move-path records; after merging spelling variants and keeping only each researcher's immediately previous employer, 51 distinct moves remain, spanning February 2025 through September 2026 across eight frontier labs. Every move is publicly reported and backed by at least two independent hosts — the set is not provably exhaustive, since no authoritative registry of lab personnel exists. A few researchers moved more than once and correctly appear on several rows.

Publicly reported and corroborated researcher moves between frontier AI labs; 51 distinct moves (from 55 corroborated records) between eight labs, Feb 2025 – Sep 2026, research current as of 2026-09-05. Each row is one researcher/from-lab/to-lab/month path backed by at least two independent web hosts; the month is the move or announcement month when an exact start date was unavailable. Alternative historical-origin records for the same researcher, destination and month were reduced to the immediately previous employer; spelling variants merged. Not an exhaustive registry of personnel changes.
