Google has announced a leadership overhaul of its AI division, with AI chief Demis Hassabis leaving his main managerial role and several leaders of its Gemini model, including veteran engineer Jeff Dean, departing the company. He will hold the title of senior vice president, rather than CEO, of the business unit, in addition to his parallel role as Alphabet’s chief AI architect. In his company memo, Hassabis touted the “great progress” on Google’s AI models including an unreleased upgrade called Gemini 4. On the defensiveIn 2023, after the launch of OpenAI’s ChatGPT caught Google off guard, Pichai announced the merger of DeepMind and Google Brain into a new organisation called Google DeepMind. The same week, senior research scientist John Jumper, who won a Nobel Prize alongside Hassabis ‌in 2024, said he would join Anthropic.
