Several top DeepMind researchers, including Jeff Dean, Sanjay Ghemawat, Oriol Vinyals, and Quoc Le, have left to co-found Discovery Loop, a public benefit corporation focused on automating machine learning research. Demis Hassabis will transition from CEO to Chair and Chief Scientist, while Koray Kavukcuoglu steps up as SVP. This leadership shakeup signals a significant shift for DeepMind.

Jeff Dean, Sanjay Ghemawat, Oriol Vinyals, and Quoc Le leave DeepMind to co-found Discovery Loop, with Demis Hassabis moving to Chairman and Koray Kavukcuoglu promoted to SVP. This is not just a personnel change; it may signal a shift in AI research paradigms.
On August 5, 2026, Jeff Dean announced on X that he, along with Sanjay Ghemawat, Oriol Vinyals, and Quoc Le, co-founded Discovery Loop, a public benefit company dedicated to automating machine learning, science, and engineering. These four are considered among the most senior engineering and research talents in Google's history, and their collective departure has been called 'the end of an era' by Latent Space.
On the same day, Demis Hassabis announced his transition from CEO of Google DeepMind to Chairman and Chief Scientist at Alphabet, focusing on long-term strategy and scientific breakthroughs. Koray Kavukcuoglu was promoted from CTO to SVP at DeepMind, responsible for Gemini, frontier research, and product/development teams.
Discovery Loop is not positioned as another general-purpose model startup, but explicitly targets autoresearch and automated discovery loops, covering scientific and engineering workflows. This technical direction is interpreted as AI-for-science becoming a major frontier, not a secondary task.
The seed round is led by Radical Ventures and Khosla Ventures, with participation from Lightspeed, Kleiner Perkins, Doerr Capital, and Alphabet. Google also invested in the new company, and all departures are described as 'very amicable.'
Latent Space raises a key question: Why couldn't Discovery Loop be done inside Google? The article suggests that historically, Gemini papers had 1000+ co-authors, yet these four 'superhumans' chose to start anew, possibly reflecting limitations in internal innovation mechanisms.
Combined with previous departures of John Jumper and Noam Shazeer, as well as David Silver, Denny Zhou, and others, and with Gemini Pro not updated for 6 months, outsiders can't help but wonder what's happening inside Google AI.
The market reaction is not merely 'big names leaving Google,' but that those most associated with Google's deep infrastructure, model building, and research execution stack are now diving into automated science. Comments from Nathan Lambert, Andrew Ng, and others frame this as a historic inflection point for Google AI efforts.
Although Google still possesses strong models, talent teams, excellent compute and infrastructure, and the largest trove of training data in human history, whether this series of changes heralds 'the beginning of the end' or 'the prelude to a great comeback' remains undetermined.
This report is primarily based on secondary reporting from Latent Space, which cites original tweets from Jeff Dean and Demis Hassabis. The tweet content is first-hand statements, but analyses regarding reasons for departure and internal dynamics are speculative. Information such as seed round investors comes from Latent Space's retelling and has not been independently verified.
The departure of DeepMind's four titans to found Discovery Loop marks a potential shift in AI research focus from general models to automated science. While Google still retains advantages, signs of talent drain and stalled product updates place it at a strategic crossroads.
