Curated list of publicly documented lab-to-lab moves: 31 rows, one per move event, January 2025 – August 2026, compiled from live web coverage as of 2026-08-30. "Frontier labs" means OpenAI, Anthropic, Google DeepMind, Meta Superintelligence Labs, xAI, Safe Superintelligence and Thinking Machines Lab; direct moves by hands-on researchers or technical research leaders only. Month is the reported announcement or effective month. The sources column counts corroborating public reports — a strength-of-documentation signal, not importance. Undisclosed personnel changes are not captured.
