AI leadership changes and startup plans

As reported by CNBC, citing Google, the company is reshaping its AI divisions, with chief scientist Jeff Dean leaving to start his own company after nearly three decades at the search group. Google said in a blog post that the move is amicable and that it plans to invest in Dean’s startup.

Alphabet CEO Sundar Pichai told staff that Dean wants to try something new after an "incredible 27-year run". Pichai said Dean and Google senior fellow Sanjay Ghemawat are launching an independent public benefit corporation focused on accelerating discoveries in machine learning, science and engineering.

Demis Hassabis, the CEO of Google DeepMind, is moving into a chairman role at the unit. Koray Kavukcuoglu, currently DeepMind CTO and chief AI architect, is taking over day-to-day leadership of the AI division with the title of senior vice president.

Kavukcuoglu is set to lead development of Gemini 4, Google’s next major AI model, and will report directly to Pichai. Hassabis said in a note to employees that he is handing over daily operational duties so he can focus on broader strategic priorities and global AI matters with Pichai.

Competitive and financial pressure on Google

The management changes come as Google faces a fast-moving AI race against OpenAI and Anthropic, while also expanding infrastructure needed both for its own computing demands and for cloud customers. The company is trying to maintain its position in frontier model development as costs across the sector remain high.

Google shares fall 5% in Wednesday trading. In the latest quarter, the company turns cash flow negative for the first time on record because of capital expenditures, while forecasting full-year capex of up to $205 billion.

Dean has long been associated with some of Google’s most important technical advances since joining in 1999. Hassabis, who co-founded DeepMind before Google acquired the lab in 2014, has in recent years led most of Alphabet’s foundational AI work.

In our earlier coverage of SpaceX’s first post-IPO earnings, we explained how strong revenue growth was eclipsed by investor unease over a sharp, AI-driven surge in capital spending. We also noted that the capex jump helped fuel a steep share-price decline, as the market demanded clearer discipline and a more convincing path to profitability.
