- #8Apple says more ex-employees may have taken confidential data to OpenAI
Apple is seeking a preliminary injunction against OpenAI, alleging more former employees may have taken confidential data to the AI model maker. Apple aims to prevent OpenAI from developing AI devices or products using its technology. OpenAI, however, claims Apple made errors, including emailing the wrong person and misrepresenting discussions with its general counsel. OpenAI also suggests Apple's "residual access" issue, allowing former employees system access, points to Apple's poor security procedures.
