Apple’s next major software story may be shaped by a partner as much as by its own engineering. According to Bloomberg's Mark Gurman in his latest newsletter, Apple and OpenAI are planning a major joint announcement at WWDC after reaching an agreement to integrate OpenAI's technology into iOS 18.
What the Apple and OpenAI agreement covers
The reported agreement would place OpenAI's technology inside iOS 18, Apple’s next iPhone operating system update. The source does not describe the exact user interface or the full list of features tied directly to OpenAI, but it says OpenAI is currently working to provide the necessary capacity for the expected influx of users.
That detail matters because Apple’s platform can quickly turn a software feature into a mass-market service. If OpenAI technology becomes part of iOS 18, the demand profile would be very different from a standalone app or optional web tool. The report frames capacity preparation as a live part of the work already underway.
The announcement is expected at WWDC, Apple’s developer event. A joint announcement there would put the partnership in front of the developers and users watching Apple’s next software cycle, while also making AI a central part of the iOS 18 story.
Apple is pairing local AI with cloud services
Apple has focused primarily on local AI capabilities, according to the source. At the same time, it also wants to offer cloud services and is upgrading its data centers to do so.
The reported AI plans include several practical features rather than only a chatbot experience. The source lists improvements to Siri, automatic summaries of notifications and news articles, and transcription of voice memos.
Those features point to a strategy built around everyday operating system tasks. Instead of treating AI as a separate destination, Apple appears to be preparing AI functions that sit inside familiar iOS workflows: asking Siri for help, catching up on notifications, reading news summaries, or turning spoken memos into text.
The cloud element is important because not every AI function is necessarily handled on a device. The source says Apple is upgrading its data centers to support cloud services, while also keeping a primary focus on local AI capabilities. That combination suggests Apple wants both device-based AI and cloud-based support available in the same broader product direction.
Why OpenAI fills a gap for Apple
Gurman says Apple does not yet have its own chatbot like ChatGPT or Google Gemini, even though the company knows users expect such a feature. The report also says executives have admitted internally that Apple is behind the curve in AI.
That explains why the OpenAI agreement could be useful in the short term. Apple can rely on its own AI models for parts of the experience while using OpenAI where it does not yet have a comparable product ready for users.
According to the report, Apple currently believes its own AI models combined with OpenAI are sufficient. However, the agreement is not viewed as a long-term solution. That makes the arrangement look less like a final AI strategy and more like a bridge for iOS 18 while Apple continues developing its own capabilities.
The source also says there is still no agreement with Google on integrating Gemini, and discussions are ongoing. That leaves OpenAI as the reported partner for the WWDC announcement, while Google remains part of a separate unresolved discussion.
The search question remains complicated
The report also raises a wider issue: Apple could revisit the search engine question. But the economics are difficult because Google pays Apple about $20 billion a year to be the default search engine on Apple devices.
For Apple to make its own search engine economically viable, it would have to make that amount of money itself. The source also notes that generative AI search is neither technically nor legally ready.
Google's broader rollout of AI-generated search results with the "Search Generative Experience" is presented as an example of the challenge. According to the source, the AI results are flawed, and site owners reject them because they reduce traffic.
That context separates Apple’s reported iOS 18 AI partnership from a much larger search replacement effort. Adding OpenAI technology to iOS 18 may help Apple answer user expectations around AI, Siri and summaries. Replacing the default search engine arrangement would require solving a separate business problem and a separate product problem.
What to watch at WWDC
The reported WWDC announcement will likely be judged on how clearly Apple connects its own AI work with OpenAI's technology. The key question is not only whether OpenAI appears in iOS 18, but how Apple presents the relationship between local AI capabilities, cloud services and the features users will actually see.
Based on the source, the main areas to watch are:
- How OpenAI's technology is integrated into iOS 18.
- What Apple says about improvements to Siri.
- How automatic summaries of notifications and news articles are shown.
- How transcription of voice memos fits into the broader AI update.
- Whether Apple explains the role of cloud services alongside local AI capabilities.
The reported deal gives Apple a way to bring a major AI name into its software update while it continues building its own models. It also puts OpenAI in front of a potentially large group of iOS 18 users, which explains why capacity is part of the preparation described in the report.
For now, the picture is straightforward: Apple and OpenAI have reportedly reached an agreement, WWDC is the expected stage, and iOS 18 is the software platform where the partnership is set to appear.
