Google reshuffles its AI leadership: Demis Hassabis moves to chief scientist, Jeff Dean departs

Key points

• Demis Hassabis, co-founder of DeepMind, was named chief scientist of Alphabet and chair of Google DeepMind on Wednesday.
• Koray Kavukcuoglu, previously DeepMind's chief technology officer, becomes Google's senior vice president of DeepMind and now reports directly to CEO Sundar Pichai.
• Jeff Dean, Google's 30th-ever employee and until now chief scientist of Google DeepMind, is leaving to co-found a new AI company called Discovery Loop.
• Google will be a founding investor in Discovery Loop.

Google made its biggest AI leadership reshuffle in years on Wednesday, as first reported by The Verge AI. The moves centre on three people who have shaped the company's AI ambitions for over a decade.

Demis Hassabis, who co-founded the British AI research lab DeepMind before Google acquired it, is stepping into a new role as chief scientist of Alphabet, Google's parent company, and chair of Google DeepMind. He will no longer run DeepMind's day-to-day operations. He keeps his position leading Isomorphic Labs, a Google subsidiary that uses AI to search for new medicines.

"I've always believed the No.1 application of AI should be to improve human health," Hassabis wrote in a message to staff. "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."

Who is now in charge of DeepMind?

Koray Kavukcuoglu takes over day-to-day leadership. He was DeepMind's chief technology officer and also holds the title of Google's chief AI architect, a role he keeps. He reports directly to CEO Sundar Pichai.

Hassabis said he will "continue to work closely with Sundar on strategic and global AGI matters", where AGI, or artificial general intelligence, refers to the long-term goal of building AI that can match or exceed human-level reasoning across a wide range of tasks. He will also advise Kavukcuoglu and other DeepMind leaders.

What is Jeff Dean doing next?

Dean is leaving Google entirely. He is one of the most storied engineers in the company's history, its 30th employee, and the person widely credited with building the computing systems that made modern AI at Google possible.

He is co-founding Discovery Loop alongside Google Fellow Sanjay Ghemawat, an engineer who has worked alongside Dean for decades. Discovery Loop is structured as a public benefit corporation, a legal company form that commits it to a public goal alongside making money.

The company's stated aim is to build AI systems that can automatically solve hard problems in science and engineering, speeding up the pace of discovery in fields like medicine and materials science.

Google will act as a founding investor, meaning it puts money in from day one.

What does this mean for ordinary people?

For now, nothing changes in Google's products. These are internal leadership shifts, not product announcements.

Longer term, the moves signal where Google's most senior AI thinkers want to focus their energy: drug discovery, scientific research, and the broader question of where AI goes next. If those efforts succeed, the people who benefit will be patients waiting on new treatments and researchers trying to solve problems that have resisted human effort for generations.

Common questions

Is Google weakening DeepMind by moving Hassabis out?

Not necessarily. Hassabis moves to a higher-level role across all of Alphabet, not out of the building. Kavukcuoglu has been at DeepMind for over a decade and co-led work on several of its most significant research projects.

What is Discovery Loop, and should I pay attention to it?

It is a brand-new company with a broad mission and Google's backing. It has no products yet. Worth watching if you follow AI research, but nothing for consumers to act on today.
