Which AI researchers moved between frontier labs since 2025 — who left which lab, where they went, and in which month?
Publicly reported and vetted direct lab-to-lab moves, January 2025 through August 2026, across six frontier labs; each strand below is one researcher's move in its reported month.
Each strand runs from the lab a researcher left to the lab they joined, placed at the reported month. Strand colour marks the destination lab. Hover a strand or a lab lane to focus it.
| Month | Researcher | Left | Joined | Role or focus | Source |

Publicly reported moves found and vetted, not an exhaustive employment census: 21 direct lab-to-lab moves by 19 researchers, January 2025–August 2026. "Frontier lab" means an organization building state-of-the-art general-purpose foundation models, including Thinking Machines Lab. Month is the reported joining month where available, otherwise the announcement month. Meta Platforms, Meta AI and Meta Superintelligence Labs are shown as Meta; Google and Google DeepMind as Google DeepMind. Duplicate and conflicting press reports were reconciled to one row per move; unvetted candidate rows were cut.
