OpenAI has come out swinging in its legal battle with Apple—and brought receipts.

The AI lab published a response—along with a tranche of private emails and messages—pushing back on some of the claims in Apple’s lawsuit filed last month that accused OpenAI, its hardware unit io Products, and two former Apple employees of trade secret theft.

Apple had accused the AI lab of carrying out a coordinated effort to take confidential information about unreleased Apple products and processes. The suit includes claims alleging that a former employee who joined OpenAI took advantage of a security bug, that job candidates were encouraged to bring proprietary Apple hardware into interviews, and that OpenAI leadership effectively normalized this conduct.

OpenAI’s blog post is not a legal response to the suit, but rather an effort to publicly point out flaws in some of Apple’s accusations and legal process—and potentially court public opinion.

“Apple is one of the greatest companies of all time, and built a reputation for obsessing over the smallest details,” OpenAI wrote in the blog. “This careless, aggressive, and oddly personal lawsuit sadly doesn’t live up to that reputation.”
