The rows cover 56 corroborated moves by 37 named researchers between frontier-model labs, January 2025 through November 10, 2026; each move is backed by reporting on at least two independent hosts (95 hosts in all). This is not a census — no public universe of frontier-lab employment changes exists, and private or unannounced moves cannot be observed; some researchers appear in more than one row.
Inclusion rule: technical AI researchers, research engineers, model technical leads and scientist-founders moving directly between organizations training frontier general-purpose models or serious newly founded frontier-model labs. Excluded: ordinary software companies, universities, policy roles, non-research executives, infrastructure-only hires, advisers, internal transfers and historical affiliations mistaken for direct moves.
Each ribbon is one move: left bar is the lab left, right bar the lab joined; ribbon colour marks the lab left. Hover or tap a ribbon for the researcher, month and role; hover a lab for who left and joined. Numbers beside bars count displayed moves, not unique people.

One row per researcher–origin–destination–month move between frontier AI labs: 56 rows, 37 unique researchers, Jan 2025 – Nov 10, 2026, as of 2026-11-10. Built from broad web searches over OpenAI, Anthropic, Google DeepMind, Meta/FAIR/MSL, xAI, Thinking Machines Lab, SSI, Mistral and other frontier startups; candidates deduplicated by normalized researcher/origin/destination/month, kept only with month-specific, multi-host corroboration (≥2 independent hosts, 95 distinct hosts total). Numbers count moves, not unique people. Each table row shows up to three corroborating links for space.
