“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 surfaced 46 distinct, multiply reported researcher moves between frontier-model labs from February 2025 through September 2026, each backed by at least two independent source hosts. Scope: technical researchers, research engineers and technical research leaders moving directly between organizations building frontier general-purpose foundation models — including new labs such as Thinking Machines Lab and AMI Labs — and excluding universities, ordinary tech firms, advisers and operations-only executives. The public record is not a registry, so this is a researched, multiply sourced set rather than a guaranteed-exhaustive one.

Evidence: a web scan of 51 reported researcher moves between frontier-model labs, February 2025 – September 2026, deduplicated to 46 distinct moves (five rows merged for stale affiliations or lab-name duplicates, e.g. Google vs Google DeepMind). “Month” is when the move began or was publicly announced, depending on what sources reported. Each move is backed by at least two independent source hosts; one representative source is linked per row and additional mention counts were cut for space.
