Google restructured command of its flagship AI lab on August 5, moving Demis Hassabis out of the chief executive seat at Google DeepMind and into a chairman role plus chief scientist of Alphabet, while Jeff Dean walked out after 27 years to launch a research startup that Alphabet itself is funding. The reshuffle pulls Google’s two most recognizable AI leaders from day-to-day model work in one announcement, arriving as AI infrastructure spending was already straining the company’s books. Investors did not read it as routine succession: Alphabet shares dropped more than 5 percent following the news, Implicator AI reported the same day.
Koray Kavukcuoglu, DeepMind’s technical leader for more than 13 years, becomes senior vice president and now reports directly to chief executive Sundar Pichai. He inherits Gemini development, frontier research, the consumer Gemini app and the developer teams, including the unreleased Gemini 4. Pichai’s internal memo credits Kavukcuoglu with starting DeepMind’s original deep-learning group and leading early work on WaveNet and DQN. Hassabis stays in charge at Isomorphic Labs, the Alphabet subsidiary applying its models to pharmaceutical research, and will work out of DeepMind’s Platform 37 offices in London, advising Pichai on strategy rather than running the lab day to day.
Dean, 58, joined Google as its 30th employee in 1999 and helped design MapReduce, BigTable and Spanner, distributed-systems software that let Google’s search scale globally and that the wider industry later copied. Only two people at Google have ever earned senior fellow, the company’s top technical title: Dean and his longtime collaborator Sanjay Ghemawat, according to The New York Times. Dean is taking Ghemawat with him. Two more DeepMind researchers, Oriol Vinyals and Quoc Le, are co-founding the new venture alongside them: a public-benefit company they call Discovery Loop, built to run the scientific method as software, propose a test, build what is needed to run it, evaluate the outcome, repeat. Longer term, the founders want to point that loop back at their own models, a strategy known as recursive self-improvement.
Khosla Ventures and Radical Ventures backed Discovery Loop alongside Alphabet, which also agreed to supply the startup’s computing capacity for its first year. None of the three investors disclosed the round’s size or the company’s valuation. Vinod Khosla told WIRED he met the four founders in secret on a Saturday, to avoid tipping off Google, and called them “the ultimate superstar team.” Vinyals was candid about the current gap in the plan: models today, he said, are not yet strong at generating the ideas an automated researcher would need to test.
The stock reaction did not happen in a vacuum. Google’s operating cash flow turned negative last quarter, a first for the company, as capital spending accelerated; CNBC reported that Google is now guiding toward roughly $205 billion in capital outlays for 2026. Separately, Axios reported that Gemini 3.5 Pro has slipped by months and that DeepMind staff have grown frustrated through a string of exits, with unnamed sources pointing to low morale. Google’s own memo says the Gemini app has surpassed 950 million monthly users, a figure the company has not opened to independent audit.
Read together, the two exits describe different problems. Hassabis is moving toward a symbolic, Alphabet-wide role while an operations-focused executive takes the wheel on shipping Gemini, the kind of change a company makes when it wants faster releases more than research vision. Dean’s exit is a talent story: an architect of the infrastructure the AI industry runs on took three senior researchers and Google’s capital to build a competitor to Google’s own long-term thesis, that AI can eventually run its own research loop. Tim Rocktäschel left DeepMind earlier this year for a similar mission at Recursive Superintelligence and described the appeal in blunt terms: startups move faster, with fewer people and less bureaucracy. He is now the second senior DeepMind researcher this year to make that complaint by leaving.
For anyone tracking who controls Gemini’s roadmap, Kavukcuoglu is now the name to watch, not Hassabis, and Gemini 4’s release timeline is the first test of whether the new structure ships faster than the old one. Teams benchmarking against Gemini 3.5 Pro this quarter should plan around Axios’s reported delay, not Google’s public schedule.
