Altman’s chat with the ex-Apple design chief Ive will be a highly anticipated part of this year’s event.
OpenAI rocked the tech sector in May when it announced it would buy Ive’s AI devices startup io for about $6.4 billion.
Ive is responsible for designing Apple‘s most iconic products, including the iPod, iPhone, iPad and MacBook Air. He is now overseeing “deep creative and design responsibilities across OpenAI,” according to a blog post.
The company has kept its work with Ive under wraps, but a screen-less hardware device is reportedly in the works, according to several media outlets.
