Ten publicly reported researcher moves between frontier AI labs — OpenAI, Anthropic, Google DeepMind, Meta AI / Superintelligence Labs and Microsoft AI — from January 2025 through the scan date of 28 August 2026. This is a documented public-reporting list, not an exhaustive personnel census: some appointments are private, or reported without a precise month.

Method: documented moves between frontier labs (OpenAI, Anthropic, Google DeepMind, Meta AI / Superintelligence Labs, Microsoft AI, with xAI and Mistral in scope but no reported rows), compiled from public reporting scanned on 28 August 2026. 10 moves after deduplicating John Jumper, Noam Shazeer and Ruoming Pang across sets, normalising "Google" to Google DeepMind and Meta variants to Meta AI / Superintelligence Labs, and excluding one row (Ethan Knight) as a false extraction from an article about Ruoming Pang. Month reflects the strongest available source; "2 reports" flags corroboration, and single-source rows are not thereby disproven. Not an exhaustive census — private or undated appointments are absent.
