Noam Shazeer, the engineer who co-wrote the seminal 2017 paper that made ChatGPT, Gemini, and Claude possible, has quit Google to join OpenAI. His departure comes less than two years into his return, after the search giant spent roughly $2.7 billion (£2 billion) on a technology licensing deal to bring him back.
Shazeer announced the move in a post on X on Wednesday, calling it a 'difficult decision to move on' before adding that he was excited to work with the team at the ChatGPT maker. The step comes just months before OpenAI's planned listing, which Goldman Sachs and Morgan Stanley are advising on at a reported valuation of up to $1 trillion (£751 billion).
