Still, it’s a reminder of what a difficult partner Apple can be for major software companies. The iPhone is an enormously attractive platform for growth, but it’s fully under Apple’s control — and companies that build there are only guests. From Google to Adobe, there’s a long history of Apple showing guests the door when they seem as if they’re getting too comfortable.

The OpenAI partnership, announced at Apple’s Worldwide Developers Conference in June 2024, wove ChatGPT into Apple’s operating systems as an option within Siri and as part of the iPhone’s Visual Intelligence feature (allowing users to use their camera to analyze their surrounds and send photos to ChatGPT with related questions).

OpenAI, along with industry watchers, expected the deal might eventually funnel billions of dollars in new subscriptions its way and give the company prime real estate across one of the world’s most-used mobile ecosystems. Instead, Bloomberg reports, OpenAI has grown increasingly aggravated, complaining that the integration has been buried, its features hard to find, and that revenue from the tie-up is nowhere close to projections. “They basically said, ‘OpenAI needs to take a leap of faith and trust us,’” one OpenAI executive told Bloomberg. “It didn’t work out well.”

Apple, for its part, has its own grievances, including concerns about OpenAI’s privacy standards and, according to Bloomberg, irritation over OpenAI’s push into hardware, an effort led by former Apple executives including ex-design chief Jony Ive.
