Apple on Friday accused OpenAI of stealing trade secrets as it seeks to build its own hardware for ChatGPT, a major rupture in a partnership between the iPhone maker and the artificial intelligence company.
Apple said in the lawsuit filed in a California federal court that the theft of its trade secrets was part of a “coordinated pattern of misconduct at an institutional level” by OpenAI.
“This case is about Apple’s former employees stealing Apple’s trade secrets for the benefit of OpenAI,” the filing says.
“Apple brings this suit to put a stop to it.”
Two former Apple employees who now work for OpenAI are also named as defendants.
One is Tang Tan, who helped design the iPhone, Apple Watch and iPod and is now OpenAI’s chief hardware officer.
The other is Chang Liu, a former electrical engineer Apple says it entrusted with some of its most sensitive product development efforts before Liu left Apple to join OpenAI earlier this year.
OpenAI did not immediately respond to requests for comment.
OpenAI has never said exactly what type of device it is building but has described it as an effort to find a new way of interacting with AI that goes beyond “traditional products and interfaces.”
It’s part of a broader push to create a physical embodiment of the latest AI advances, a decade after Amazon and Google introduced screen-free talking speakers into homes.
The lawsuit claims the effort was built partly on knowledge stolen from Apple.
