Apple and OpenAI inked a deal to integrate ChatGPT with Siri as part of iOS 18 in 2024. According to a new report today, however, OpenAI is displeased with how the partnership has played out and is considering taking legal action against Apple.

According to Bloomberg, OpenAI lawyers are working with an outside legal firm “on a range of options that could be formally executed in the near future.” One possible outcome is that OpenAI sends Apple a notice “alleging breach of contract without necessarily filing a full lawsuit at the outset.”

The report says:

“OpenAI believed that the companies’ partnership, which wove ChatGPT into Apple software, would coax more users into subscribing to the chatbot. It also expected deeper integration across more Apple apps and prime placement within the Siri assistant.”

An unnamed OpenAI executive, quoted by Bloomberg, alleges that the company has “done everything from a product perspective,” while Apple has not held up its end of the deal.
