[Apple and OpenAI Partnership Breaks Down, OpenAI Plans Legal Action] According to Deep Tide TechFlow on May 18, as reported by Bloomberg, the two-year partnership between Apple and OpenAI has encountered serious fractures. OpenAI believes the collaboration has fallen short of expectations—ChatGPT's visibility within the Apple ecosystem is insufficient, its feature access points are obscure, and subscription conversions are far below projections. OpenAI has reportedly teamed up with external law firms to explore legal options, including issuing a breach of contract notice to Apple. OpenAI executives stated that Apple 'did not even make an honest effort.' No final decision has been made yet, and OpenAI still hopes for an out-of-court resolution. Meanwhile, Apple plans to introduce a multi-AI integration mechanism in iOS 27, testing the incorporation of Anthropic Claude and Google Gemini, further weakening OpenAI's exclusive position.
