Apple has escalated tensions in the competitive AI labor market by filing a lawsuit against OpenAI, accusing the AI research company of illicitly acquiring sensitive information through its hiring process. The lawsuit targets OpenAI, its hardware division IO, and former Apple employees now working at OpenAI, marking a significant development in the ongoing battle for top artificial intelligence talent.

The complaint details how OpenAI allegedly instructed job candidates to review confidential Apple materials and prepare in-depth technical presentations based on their work at Apple. It also claims OpenAI interviewers requested candidates to bring physical Apple components such as batteries, logic boards, and glass samples to “show and tell” sessions. Apple argues these actions amounted to a concerted effort to extract proprietary knowledge and circumvent corporate security.

Apple alleges that during interviews, OpenAI recruiters probed candidates with questions designed to reveal secret supplier details, vendor relationships, and internal engineering strategies. The lawsuit accuses OpenAI of deliberately seeking trade secrets, even going so far as to use Apple’s internal code names to mask their inquiries. According to Apple, internal investigations uncovered incriminating messages on company-issued laptops that suggest an organized attempt to subvert Apple’s security protocols.

A key figure in the lawsuit is Tang Tan, a former Apple employee now leading OpenAI’s hardware division. Apple contends Tan warned recruits about Apple’s offboarding security checks using internal documents, and that OpenAI advised departing Apple employees to avoid signing exit paperwork. The suit claims some employees joined OpenAI without giving the mandated two weeks’ notice and ignored Apple’s security staff, potentially to conceal the mishandling of confidential information.

In response, OpenAI stated it does not seek other companies’ trade secrets and emphasized its commitment to developing innovative technology that benefits users worldwide. This lawsuit highlights the widening rift between tech giants as they aggressively pursue the best minds in AI development, blurring ethical lines in a fiercely contested talent war.
