Named AI researchers who moved directly between frontier general-purpose model labs, January 2025 through 27 August 2026. A live-web extraction substantiated 23 reported records, merged here to 22 distinct researcher-route moves after folding one duplicate origin for Noam Shazeer. The requested 50+ threshold is not substantiated.

Method: a broad live-web scan across 17+15+16 diverse search-query families and thousands of deduplicated pages; exact named employment moves were semantically extracted and restricted to direct moves between organizations operating frontier general-purpose model labs. 23 extracted records, merged to 22 distinct researcher-route moves — the two Noam Shazeer records name the same origin organization (Google Gemini is part of Google DeepMind). Three rows are dated by source publication month rather than a directly stated move month, marked "inferred" in the table. A number in the diagram counts researchers on that route. Coverage through 2026-08-27; this is a verified partial census, not a complete list of moves.
