Barret Zoph Returns to Google DeepMind Amidst Intense AI Talent Wars

量子位 · wechat · 2026-08-28

Barret Zoph, a former OpenAI research VP and co-founder/CTO of Thinking Machines Lab, has returned to Google DeepMind as a research VP. His career is marked by significant contributions including Neural Architecture Search (NAS) and the Switch Transformer, as well as leading post-training efforts at OpenAI. His return comes shortly after a tumultuous period at Thinking Machines Lab, where he and co-founders departed following reported conflicts with CEO Mira Murati over authority and performance.

Context of Talent Wars:

Zoph's move highlights the intense “free agency” market for top AI research leaders. Google DeepMind is experiencing a notable surge in talent turnover, with its inflow-to-outflow ratio dropping from 12:1 in mid-2023 to 2:1 in mid-2026. Data shows that 25% of departing DeepMind talent joined Anthropic, while 21% went to Meta and 14% to OpenAI. This shift coincides with major leadership changes at Google, including the departures of Demis Hassabis from daily management and Jeff Dean, as well as Noam Shazeer leaving for OpenAI.

Drivers of Turnover:

According to reports, factors driving researchers away from Google include lucrative offers from competitors, dissatisfaction with Google's position in the AI race, low internal morale, and the appeal of pre-IPO equity at rivals like OpenAI and Anthropic. Additionally, some researchers feel that Google's increasing focus on Gemini commercialization is squeezing out the long-term, open scientific exploration that originally defined DeepMind.
