Google has announced a major reshuffling of its AI leadership, with Demis Hassabis transitioning from leading Google DeepMind to become chair of Google DeepMind and chief scientist at Alphabet, while focusing on using AI to develop drugs through Isomorphic Labs.
Koray Kavukcuoglu, previously DeepMind's CTO, is taking over day-to-day leadership of DeepMind.
In a separate move, veteran Google researcher Jeff Dean and Google Fellow Sanjay Ghemawat are leaving to start Discovery Loop, an AI-focused public benefit corporation backed by Google as a founding investor.
What happened
Demis Hassabis is moving from leading Google DeepMind to become chair of Google DeepMind and chief scientist at Alphabet. Koray Kavukcuoglu, formerly DeepMind's CTO, is stepping up to become Google's SVP of DeepMind and will report to CEO Sundar Pichai. Meanwhile, veteran Googler Jeff Dean and Google Fellow Sanjay Ghemawat are leaving to form Discovery Loop, an AI-focused public benefit corporation, with Google as a founding investor.
Why it matters
The moves signal a shift in Google's AI strategy under Pichai. Hassabis's focus moves explicitly to health and disease research through Isomorphic Labs, which he will continue to lead. Kavukcuoglu takes on day-to-day leadership of DeepMind, while Hassabis focuses on "strategic and global AGI matters." The departure of Dean, Google's 30th employee and longtime chief scientist of Google DeepMind, reflects a broader reconfiguration of how the company is organizing its AI talent.
What to watch
Discovery Loop says its mission is to "build AI solutions that can automatically solve important problems in machine learning, science, and engineering" and "deliver technology solutions that improve people's lives on a global scale." Google's role as a founding investor in this new entity will determine how closely the company remains involved in Dean and Ghemawat's work.
Google announced the leadership changes on Wednesday through CEO Sundar Pichai. Demis Hassabis, who has led Google DeepMind, is transitioning to a strategic role: he will become chair of Google DeepMind and chief scientist at Alphabet, while continuing to lead Isomorphic Labs, the company's drug-development effort that uses AI. In a message to staff, Hassabis framed his shift as a move to focus on his longtime conviction: "As you've heard me say many times, I've always believed the No. 1 application of AI should be to improve human health. It's time for AI to prove its unequivocal value to the world, and what better way to demonstrate that than to help finally cure diseases like cancer." He will advise Kavukcuoglu and other DeepMind leads on strategic matters while working closely with Pichai on "strategic and global AGI matters."
Koray Kavukcuoglu, who previously served as DeepMind's CTO, assumes the day-to-day leadership role as Google's SVP of DeepMind, reporting directly to Pichai. He will also retain his position as Google's chief AI architect.
In a parallel move, Jeff Dean—a Google veteran who served as the chief scientist of Google DeepMind and was the company's 30th employee—is leaving Google along with Google Fellow Sanjay Ghemawat to start Discovery Loop, an AI-focused public benefit corporation. Google will be a founding investor. Discovery Loop describes its mission on its website as building "AI solutions that can automatically solve important problems in machine learning, science, and engineering" with the goal of accelerating "the pace at which we conduct engineering and scientific discovery" to bring "the benefits of science and technology to the world much faster."
Google's leadership reshuffle reflects a deliberate rebalancing of its AI organization under CEO Sundar Pichai. The moves separate Hassabis's strategic vision—particularly his stated focus on using AI to improve human health and cure diseases—from the day-to-day operational leadership of DeepMind. This allows Hassabis to concentrate on what he calls the "No. 1 application of AI," which he frames as advancing medicine, while Kavukcuoglu takes the helm of the research organization itself.
The departure of Jeff Dean, one of Google's earliest employees and a towering figure in AI research, to form a new company signals that Google's internal structure may no longer be the only home for cutting-edge AI talent. By making Google a founding investor in Discovery Loop rather than retaining Dean internally, Pichai appears to be positioning the company as an ecosystem participant rather than insisting on a unified internal structure. Dean and Ghemawat's stated mission—to "automatically solve important problems in machine learning, science, and engineering"—overlaps with DeepMind's research agenda but suggests a focus on practical problem-solving and scientific discovery rather than foundational AI research.
