Alphabet appoints Demis Hassabis as Chief Scientist; Koray Kavukcuoglu named Google DeepMind CEO

Alphabet has announced a major reshuffle of its artificial intelligence leadership, appointing Demis Hassabis as Chief Scientist of Alphabet and Chair of Google DeepMind, while naming Koray Kavukcuoglu as the new Chief Executive Officer of Google DeepMind.

The leadership changes come as Google seeks to accelerate AI research and strengthen its position in an increasingly competitive race with frontier AI developers. At the same time, veteran Google AI researcher Jeff Dean is leaving the company to launch a new venture with longtime Google engineer Sanjay Ghemawat.

According to Business Insider and a blog post by Google CEO Sundar Pichai, the changes are designed to sharpen the company's focus on long-term AI research while streamlining leadership across its AI organisation.

Demis Hassabis moves into an Alphabet-wide AI role

Under the new structure, Demis Hassabis will step down from his day-to-day responsibilities as Chief Executive Officer of Google DeepMind.

He will instead serve as:

• Chief Scientist, Alphabet
• Chair, Google DeepMind

In his expanded role, Hassabis will oversee long-term AI research across Alphabet while continuing to shape the company's broader scientific direction.

According to a memo published by Google, Hassabis said he had decided it was the right time to hand over operational leadership so he could focus on the "big picture" and contribute more directly to the future of artificial intelligence.

The move gives Hassabis greater freedom to concentrate on advanced research rather than the operational demands of running one of Google's largest AI divisions.

Koray Kavukcuoglu takes charge of Google DeepMind

Koray Kavukcuoglu, previously Chief Technology Officer of Google DeepMind, has been appointed Chief Executive Officer of the division.

He will report directly to Sundar Pichai and oversee DeepMind's day-to-day operations as Google continues investing heavily in next-generation AI models and infrastructure.

The appointment marks a leadership transition within one of the technology industry's most influential AI research organisations.

Jeff Dean exits after decades at Google

The leadership changes also include the departure of Jeff Dean, one of Google's longest-serving AI researchers and engineers.

According to Business Insider, Dean will leave the company to launch Discovery Loop, a new initiative with fellow Google veteran Sanjay Ghemawat.

Dean has played a central role in Google's AI and infrastructure development over several decades, making his departure one of the most significant leadership exits from the company's AI organisation in recent years.

Google sharpens focus on frontier AI

Announcing the changes, Sundar Pichai said Google must accelerate its AI work while remaining focused on advancing the frontier of artificial intelligence.

According to Google's announcement, Pichai also highlighted the importance of shaping the future of artificial general intelligence and scientific discovery as AI development accelerates.

The leadership reshuffle comes during a challenging period for Google.

According to Business Insider, the company has faced delays in launching its next-generation AI model, while competitors including OpenAI and Anthropic have continued releasing new frontier AI systems.

The report also noted growing competition in AI coding, an area that has become one of the industry's fastest-growing commercial opportunities.

A shift towards research-led leadership

The appointment of Hassabis to an Alphabet-wide research position reflects Google's effort to separate scientific leadership from operational management.

Hassabis is widely recognised for leading several landmark AI breakthroughs, including AlphaGo and AlphaFold, both developed during his time at DeepMind.

The new structure enables him to devote more attention to long-term scientific research while operational leadership moves to Kavukcuoglu.

Leadership changes signal Google's next AI chapter

The restructuring underlines Alphabet's determination to strengthen its AI leadership as competition intensifies across the technology sector.

By expanding Hassabis' research responsibilities, promoting Kavukcuoglu to lead Google DeepMind and overseeing a transition following Jeff Dean's departure, Alphabet is repositioning its AI organisation around both scientific innovation and execution.

The leadership overhaul also reflects the increasing importance technology companies are placing on organisational design as they compete to develop the next generation of AI systems.
