Demis Hassabis steps down as CEO of Google DeepMind, the company confirmed on August 5, 2026, moving into a new role as Chair of Google DeepMind and Chief Scientist of Alphabet. Chief Technology Officer Koray Kavukcuoglu takes over daily operations as Senior Vice President, reporting to Alphabet CEO Sundar Pichai.
The change is not an exit from the company. Hassabis, a co-founder who has led DeepMind since 2010, keeps running Isomorphic Labs, Alphabet’s AI drug-discovery spinoff. He will now focus on long-term strategy for AGI (Artificial General Intelligence, AI that matches or beats human skills). The reset lands as Google fights to hold pace with OpenAI and Anthropic, both of which have hired away senior Google researchers this year. Alphabet shares fell about 4% to 5% on the news, per market reports.
StartupFeed Insight
The reporting line is the real signal here, not the title. Hassabis was a CEO; Kavukcuoglu is an SVP reporting to Pichai. That collapses a management layer and pulls Gemini closer to Alphabet’s top desk, a classic move when a research lab is told to ship faster. Founders and AI investors should watch the Gemini 3.5 Pro launch date closely: it slipped from June and is the clearest test of whether this reset works. Expect Google to ship a flagship Gemini upgrade before the end of 2026 to prove the new structure delivers speed, not just a new org chart. By Soumya Verma.
What the DeepMind reshuffle changes
The reshuffle rewires who runs Google’s most important AI unit. Demis Hassabis moves from CEO of Google DeepMind to Chair of the unit and Chief Scientist of Alphabet, while continuing to lead Isomorphic Labs. Koray Kavukcuoglu, previously DeepMind’s CTO and Google’s chief AI architect, becomes Senior Vice President and takes day-to-day control.
| Element | Detail | Notes |
|---|---|---|
| Outgoing CEO | Demis Hassabis | Now Chair of GDM and Chief Scientist, Alphabet |
| New operational lead | Koray Kavukcuoglu | SVP, Google DeepMind, 13-year veteran |
| Reports to | Sundar Pichai | SVP line, not a stand-alone CEO title |
| Scope of new SVP | Gemini, frontier research, apps | Owns Gemini model development and developer teams |
| Also departing | Jeff Dean and 3 veterans | Leaving to found Discovery Loop |
| Announcement date | August 5, 2026 | Confirmed via Sundar Pichai memo |
Kavukcuoglu now owns Gemini model development, frontier AI research, and the Gemini app and developer teams, according to Google. Pichai noted that Kavukcuoglu started the deep-learning team at DeepMind and led work on breakthroughs like WaveNet and DQN (Deep Q-Networks). You can read the framing directly in Google’s official company blog.
About Google DeepMind
Google DeepMind is Alphabet’s core artificial intelligence research lab, formed in 2023 by merging DeepMind (founded 2010 by Demis Hassabis, Shane Legg, and Mustafa Suleyman) with the Google Brain team. Headquartered in London, it builds Gemini, Google’s flagship AI model line, plus research systems such as AlphaFold. The Gemini app has crossed 950 million monthly users, per Google, making DeepMind central to Alphabet’s product and revenue plans.
Why did Demis Hassabis step down now?
Hassabis stepped down to concentrate on AGI strategy and scientific research rather than daily management. In his note to staff, he framed the shift as freeing him to work on the bigger picture as AGI, in his words, feels close at hand. Pichai said the new role lets Hassabis put his full attention on shaping the future of AGI.
I have been working towards AGI my whole life, and as we enter this pivotal moment, I am stepping into a new role as Chair of Google DeepMind and Chief Scientist of Alphabet, Hassabis wrote in his message to employees.
The timing carries weight. Google delayed its Gemini 3.5 Pro model, which Pichai had said at Google I/O would arrive around June 2026. The delay stoked investor worry that Google is slipping behind rivals who have poached its talent. Moving Hassabis to strategy and a sharp operator to delivery reads as a direct answer to that pressure.
Who is leaving with Jeff Dean?
Jeff Dean is leaving Google after 27 years to co-found Discovery Loop, a public benefit corporation. Dean, employee number 30 and a Google Brain co-founder, exits alongside Google Senior Fellow Sanjay Ghemawat, DeepMind VP Oriol Vinyals, and Google Brain co-founder Quoc Le. Google is a founding investor and cloud partner in the new venture.
Discovery Loop aims to automate machine learning, science, and engineering to speed up research. Dean has said the goal is to computerise the full loop of hypothesis, experiment, and evaluation. The seed round is co-led by Radical Ventures and Khosla Ventures, with participation from other investors, and the round is not yet closed. Dean announced the launch through his post on X.
These four exits follow earlier high-profile departures. Gemini co-lead Noam Shazeer left for OpenAI and Nobel laureate John Jumper left DeepMind for Anthropic, both in June 2026. Together the moves mark a steady drain of senior talent from Google’s AI ranks.
What does this mean for Gemini and Google?
For Gemini, the change puts one operator in charge of both research and product. Kavukcuoglu now controls model development and the Gemini app under a single line to Pichai, which should tighten the loop from lab to launch. Google is counting on a larger next model, referred to internally as Gemini 4, to close the gap in areas like coding where rivals have led.
| Rival lab | Recent Google hire | What it signals |
|---|---|---|
| OpenAI | Noam Shazeer (Gemini co-lead) | Lost a key transformer author and model lead |
| Anthropic | John Jumper (Nobel laureate) | Lost an AlphaFold co-creator from DeepMind |
| Discovery Loop | Jeff Dean and 3 veterans | Lost core infrastructure and research talent |
What makes Google’s position different is scale: the Gemini app already serves more than 950 million monthly users, per Google, giving it a distribution edge rivals cannot match yet. The open question is whether a flatter structure converts that reach into faster, better models.
What’s Next
The next milestone to watch is the delayed Gemini 3.5 Pro launch, followed by the larger Gemini 4 model now in training. A shipped flagship upgrade before the end of 2026 would show the reset is working. Kavukcuoglu has said his primary focus is delivering on the Gemini roadmap. Will a flatter, faster DeepMind be enough to pull ahead of OpenAI and Anthropic?
