OpenAI releases chat logs to counter Apple's trade secret lawsuit

Apple sued OpenAI last month alleging it stole confidential information via former Apple engineer Chang Liu. OpenAI publicly released iMessage and email exchanges it says show Apple employees contacting Liu for technical help and internal files after he left the company, calling the lawsuit "careless, aggressive, and oddly personal" and denying it has or wants Apple's trade secrets.

Why it matters: This is an unusually public fight between two AI heavyweights, with OpenAI litigating in the press as much as in court — a sign of how much reputational stakes now ride on talent disputes and IP fights in the AI race. It also underscores how porous the boundary between Apple and OpenAI's overlapping ambitions (on-device AI, the recent Siri overhaul) has become as both compete for the same engineers.
