Apple is preparing to break with its single-partner approach to generative AI. According to a Bloomberg report surfaced by MacRumors on May 5 and amplified across outlets on May 6, iOS 27, iPadOS 27 and macOS 27 will let users choose which third-party model handles Apple Intelligence tasks — including Anthropic's Claude and Google's Gemini alongside OpenAI's ChatGPT.
A new Extensions framework
The mechanism for this shift is a feature Apple is reportedly calling Extensions. As described in the reporting, Extensions will "allow you to access generative AI capabilities from installed apps on demand, through Apple Intelligence features such as Siri, Writing Tools, Image Playground and more." In practice, that means any AI vendor that ships an Extension can be assigned to handle specific Apple Intelligence workflows on the device.
Until now, Apple Intelligence has only routed select queries to ChatGPT, the result of a high-profile partnership first announced at WWDC 2024 for iOS 18 and subsequently expanded in iOS 26. The Bloomberg report indicates the new framework opens that pipeline to multiple providers, with users selecting their preferred service through a dedicated menu in Settings.
Distinct voices and clear handoffs
One notable detail in the reporting: Apple is said to be planning distinct voices depending on which model is responding. Replies generated by Apple's own system would sound different from those produced by Claude, Gemini or other partners, giving users an audible cue about which service is on the other end of a Siri query. That design choice suggests Apple wants the source of an answer to be transparent rather than blended invisibly into the assistant experience.
The baseline split between on-device and third-party work appears to remain intact. Apple's models would continue to handle privacy-sensitive and on-device tasks such as summarization, contextual suggestions and basic Siri functions, while heavier generative tasks — long-form writing, complex reasoning, creative image generation — could be routed to whichever provider the user has chosen.
Why it matters
The move would change the strategic balance for every major frontier lab. ChatGPT's exclusivity on iPhone has been one of OpenAI's most visible distribution wins of the past year. Putting Claude and Gemini on equal footing inside Apple Intelligence turns the operating system into neutral ground and pushes the competitive question down to the model layer: which provider users actually pick by default.
It is also a regulatory signal. Apple has spent the past two years under pressure from the EU's Digital Markets Act and from state-level antitrust scrutiny in the United States. A user-selectable AI provider, governed by a system-level Extensions API, mirrors the kind of choice screens regulators have demanded for browsers and search engines.
Apple has not officially confirmed any of the iOS 27 details. The plans, as described, are based on Bloomberg's reporting and could change before WWDC, where Apple traditionally previews its next-generation operating systems.
