Google has announced one of the biggest changes to its artificial intelligence leadership in years. Demis Hassabis, the co-founder and chief executive of Google DeepMind, is moving into a new role as chairman of the lab and chief scientist of Alphabet. Koray Kavukcuoglu, who has been DeepMind's chief technology officer, will take over as senior vice president of DeepMind and report directly to Alphabet and Google CEO Sundar Pichai. The moves were announced Wednesday and signal a new chapter for Google's AI organization as competition with Microsoft-backed OpenAI and other labs intensifies.

Hassabis is not leaving Google. Instead, he will take on a broader scientific role across Alphabet. As chair of Google DeepMind, he will help set the strategic direction of the lab while stepping back from day-to-day management. As Alphabet's chief scientist, he will advise on science and artificial intelligence matters across the company. He will also continue to lead Isomorphic Labs, the Alphabet business established to use AI for drug discovery and molecular biology.

In a staff message, Hassabis said he would "continue to work closely with Sundar on strategic and global AGI matters" and would "advise Koray and the fantastic DeepMind leadership team." He also explained his decision by pointing to the potential of AI in medicine: "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."

Kavukcuoglu takes the helm at DeepMind

Kavukcuoglu's promotion puts him in charge of one of the world's most prominent AI research organizations. He had served as DeepMind's CTO, overseeing the technical development of systems like AlphaGo, AlphaFold, and the Gemini family of models. In his new job, he will be Google's SVP of DeepMind, reporting directly to Sundar Pichai. He will also retain the title of chief AI architect at Google, a role that places him at the center of Google's broader AI strategy across search, cloud, Android, and other products.

The leadership change means DeepMind will continue to operate as a distinct unit under Google while plugging into the wider company. DeepMind has become central to Google's efforts to build a competitive answer to OpenAI's ChatGPT and GPT models. Gemini, the family of large language models developed by Google DeepMind, now underpins many of Google's AI-powered features, from search overviews to assistant tools and cloud APIs.

Kavukcuoglu's background is deeply rooted in deep learning. Before joining DeepMind, he worked on computer vision and neural networks, and he later became one of the lab's key technical leaders. His elevation suggests Google wants continuity in the research pipeline while giving Hassabis the freedom to focus on long-term scientific goals and external-facing initiatives like Isomorphic Labs.

Jeff Dean and Sanjay Ghemawat depart for Discovery Loop

The other major piece of the shakeup is the departure of Jeff Dean and Sanjay Ghemawat, two of Google's most influential engineers. Dean joined Google in 1999 and became the company's 30th employee. Over more than two decades, he helped build the infrastructure that powered Google's rise: MapReduce, the Google File System, Bigtable, Spanner, and TensorFlow, among other foundational systems. He later became chief scientist of Google DeepMind after Google Brain and DeepMind were merged into a single unit in 2023.

Ghemawat, also a Google Fellow, has worked closely with Dean since the early days of Google. Together, they co-created technologies that made it possible to process massive amounts of data across clusters of computers. Their research influenced thousands of engineers and laid the groundwork for modern distributed systems and machine learning platforms.

Dean and Ghemawat are now leaving to start Discovery Loop, a public benefit corporation that aims to apply AI to scientific and engineering problems. Pichai said Google will be a "founding investor" in the company. In a mission statement on its website, Discovery Loop said its goal is "building AI solutions that can automatically solve important problems in machine learning, science, and engineering." The organization says it wants to accelerate engineering and scientific discovery and ultimately build AI systems that are "a deeply positive, empowering force for humanity."

Discovery Loop's structure as a public benefit corporation is notable. Unlike a typical startup focused solely on shareholder returns, a public benefit corporation is legally accountable for its stated social mission. That makes the new company similar, in some ways, to Anthropic's decision to create a public benefit corporation for AI safety. It also allows Dean and Ghemawat to pursue an ambitious mission with backing from Google without remaining inside Google's corporate structure.

A pivotal shift in Google's AI strategy

The changes come at a moment when Google is trying to defend its status as an AI leader. OpenAI has captured widespread attention with ChatGPT, and large technology companies are spending billions on GPUs, research, and specialized AI teams. DeepMind's work on AlphaFold has already had a major impact on biology, but the recent focus has shifted toward large language models, multimodal systems, and agentic AI that can take actions on behalf of users.

By moving Hassabis into the role of Alphabet chief scientist, Google is betting that his scientific reputation and strategic vision can benefit not only DeepMind but also the broader company. Hassabis will remain involved in the company's most ambitious long-term projects, including artificial general intelligence (AGI) research. His continued leadership of Isomorphic Labs gives Google a strong presence in computational drug discovery, a field where AI has the potential to deliver tangible breakthroughs in medicine.

Kavukcuoglu's appointment ensures that DeepMind's research and development efforts remain in the hands of someone who has been part of the lab for many years. His close familiarity with the team and technical direction may help minimize disruption as DeepMind continues to integrate its work with Google's product groups. The decision to keep him as chief AI architect also suggests that Google wants a single executive who can coordinate AI efforts across the entire company.

The departure of Jeff Dean could be seen as a loss for Google. Dean is widely respected in the machine learning community and has been a bridge between Google's research and engineering organizations. But Google is not cutting ties entirely. By becoming a founding investor in Discovery Loop, Google could benefit from any new technologies that Dean and Ghemawat create. The move also follows a broader trend of senior AI researchers leaving large companies to start their own ventures, from OpenAI co-founder Ilya Sutskever's Safe Superintelligence to former DeepMind researcher Mehdi Mirza's startups.

For now, Google's message is one of continuity and evolution rather than disruption. Hassabis will stay involved in DeepMind as chair, Kavukcuoglu will run the lab on a day-to-day basis, and Dean will continue to work on AI through Discovery Loop. The reshuffle gives Google's top AI executives more room to focus on their respective strengths: Hassabis on science and medicine, Kavukcuoglu on research and product integration, and Dean on building a new AI research organization outside the corporate walls.

All of this will take shape in the coming months. Google is no longer a company where AI research happens in a single lab; it is a sprawling effort spanning multiple groups, products, and external partners. The leadership changes announced this week are an attempt to keep that effort focused while allowing some of its most prominent figures to pursue new challenges.
