Apple sues OpenAI, alleging trade-secret theft via 400+ ex-employees

Apple's lawsuit marks a dramatic rupture in a partnership that began in 2024 when Apple integrated ChatGPT into its products. The complaint alleges OpenAI misappropriated confidential AI-hardware trade secrets, naming former employees Chang Liu and Tang Tan — the latter accused of recruiting others and sharing Apple supplier information. Apple frames the 400-plus departures from its silicon-engineering, on-device-AI, and hardware-design teams as a coordinated extraction effort.

The timing is pointed. Apple Intelligence and Siri have been widely criticized as lagging frontier assistants, and OpenAI is reportedly prepping a hardware device launch and IPO — both of which the suit could disrupt. An Apple spokesperson said the company will 'always defend our teams' hard work and innovations.'

The case dominated developer forums. A Hacker News thread hit 1,179 points and 611 comments, with many drawing parallels to Waymo v. Uber; r/artificial's 'Apple just sued OpenAI. And the details are wild' pulled 481 upvotes. A follow-up thread centered on an OpenAI engineer's 'LOL' moment that allegedly set the stage for the fight. Reactions split between shock at the explicit documentation and pragmatists shrugging it off as 'one megacorp stealing from another.'

Legally, trade-secret cases turn on whether specific confidential material — not general skill — crossed over. Apple's naming of individuals and documents suggests it believes it has a paper trail, but discovery will be long, and any injunction touching OpenAI's hardware roadmap is the real stakes here.
