Google DeepMind Co-Founder Demis Hassabis Steps Down From Daily Operations

Alphabet announced a sweeping leadership shake-up at its artificial intelligence division on August 5, moving its top researcher into a broader strategic role as the tech giant faces mounting questions about its competitive footing against rivals OpenAI and Anthropic. Demis Hassabis, who co-founded DeepMind in 2010 before Google acquired it in 2014, is stepping back from the lab’s daily management to serve as chair of Google DeepMind and take on the new role of chief scientist at Alphabet.

Hassabis will also continue leading Isomorphic Labs, the tech giant’s AI drug-discovery company. The transition comes as the race toward artificial general intelligence accelerates across the tech sector. I’ve been working towards AGI my whole life and now, like many of you, I feel it is close at hand, Hassabis wrote in a blog post published August 5. He added that he wanted the time and space to focus on the big picture.

Koray Kavukcuoglu Takes the Operational Reins

Stepping into the senior vice president role to run daily operations is Koray Kavukcuoglu, who previously served as DeepMind’s chief technology officer and Google’s chief AI architect. Kavukcuoglu, a 13-year veteran of the lab, will report directly to Sundar Pichai and oversee Gemini development, frontier research, and app and developer teams.

Pichai’s memo emphasized Kavukcuoglu’s long tenure on early breakthroughs like WaveNet and DQN. In the same company communications, Pichai defended Google’s overarching competitive posture, pointing to heavy compute resources and widespread product reach. Pichai added, We have to accelerate all this work and stay focused on the AI frontier. At the same time, there’s never been a more important moment to shape the future of AGI and science.

Demis Hassabis Reportedly Planned DeepMind Exit for a Year

Jeff Dean and Senior Researchers Exit for Independent Ventures

The management shuffle coincides with a wave of high-profile exits from Google’s engineering ranks. Jeff Dean, a 27-year company veteran and most recently Google DeepMind’s chief scientist, is leaving to establish an independent public-benefit corporation named Discovery Loop alongside Google Senior Fellow Sanjay Ghemawat. DeepMind vice president Oriol Vinyals and Google Brain co-founder Quoc Le are also joining the new venture.

Jeff Dean and Google AI Researchers Leave to Launch Startup Discovery Loop

According to staff memos published August 5, Discovery Loop aims to automate machine learning, science, and engineering. Google will serve as a founding investor and cloud partner for the startup. Explaining his departure, Dean noted that operating outside a public company structure provides freedom to chase science over quarterly returns and make decisions that are not necessarily in the company’s purist financial interests.

The departures follow other recent losses. Earlier in the summer, Noam Shazeer, a previous vice president of engineering and co-lead of Gemini, left Google for OpenAI. Around the same time, DeepMind Vice President John Jumper—who shared the 2024 Nobel Prize in Chemistry with Hassabis for AlphaFold protein-structure work—left for Anthropic alongside senior researchers Jonas Adler and Alexander Pritzel.

Pressure Mounts Amid Delayed Releases and Surging AI Spending

The reorganization unfolds against a backdrop of fierce competition and financial headwinds. While Alphabet’s cloud unit posted a revenue increase of 82% year over year to reach $24.8 billion during the second quarter, capital expenditures are climbing rapidly. The company forecasts between $195 billion and $205 billion in capital spending this year, largely directed toward infrastructure supporting its AI ambitions.

At the same time, product timelines have slipped. Google had planned to release Gemini 3.5 Pro, its latest frontier model, in June, but months later the market has seen only lower-power Flash models. Bloomberg reported that the flagship model fell short of internal goals, while Axios pointed to low morale as a factor. Meanwhile, competitors OpenAI and Anthropic have continued rolling out new models.

Investor reaction to the leadership memos was swift. Alphabet shares dropped more than 4.10% on the news, giving back a portion of a 13% run-up following the company’s post-earnings low. Despite the market dip, Pichai noted that the Gemini app currently serves more than 950 million monthly users as the company attempts to streamline its research and development under its newly appointed leadership.
