Sir Jony Ive, the hugely influential British designer responsible for the look of Apple's most iconic and successful products, is joining OpenAI.
Boss Sam Altman said he was "thrilled" to be partnering with the man he called the "greatest designer in the world".
OpenAI, the maker of ChatGPT, is buying Sir Jony's startup, io, in a $6.5bn (£4.7bn) deal.
Mr Altman said he was excited to "try to create a new generation of AI-powered computers" together.
Sir Jony - who designed the iMac, iPod, iPhone and iPad - will "assume deep design and creative responsibilities" across the company, the two firms said in an announcement.
