- Jeff Dean is leaving Google after 27 years as chief scientist to co-found startup Discovery Loop with senior fellow Sanjay Ghemawat; Google confirmed the departure is on friendly terms and will invest in the new venture.
- Demis Hassabis is moving from Google DeepMind CEO to chairman of GDM while adding the title of chief scientist at parent company Alphabet, focusing on strategic and global AI matters with Sundar Pichai.
- Koray Kavukcuoglu, DeepMind's technology chief, has been promoted to head of the AI division, where he will lead development of Gemini 4 and report directly to Pichai.
- Alphabet shares dropped approximately 4% following the announcement, which landed alongside a quarter where Google turned cash flow negative for the first time on record while forecasting full-year capex of up to $205 billion.
- Google Cloud revenue surged 82% in Q2 to $24.8 billion, outpacing AWS (37%) and Azure (43%), with Pichai attributing the growth to AI infrastructure demand and Google's homegrown TPUs.
- Google released three new Gemini models a day earlier, including what it framed as its clearest counter to Anthropic's lead in cybersecurity, though the company has still not shipped the delayed Gemini 3.5 Pro.
Why it matters: Google is consolidating AI leadership under Kavukcuoglu just as it ramps capex to $205 billion and runs cash flow negative for the first time, betting that operational focus and continued cloud momentum (82% revenue growth) can fund the Gemini 4 push against OpenAI and Anthropic — the 4% share drop shows investors want proof the new structure ships faster.
