Apple is planning one of the most significant shifts in the history of its iPhone software: giving users the ability to choose which AI model powers the features built into iOS 27. Reported on May 5, 2026, by both Bloomberg and TechCrunch, the plan would allow third-party large language models — including those from Anthropic and Google — to plug into Apple Intelligence features such as Siri, Writing Tools, and Image Playground through a new framework called Extensions. The move signals a pragmatic acknowledgment from Apple that AI capability has become too competitive and fast-moving for any single company to dominate, and that openness may be the path to relevance in the AI era.
What Was Announced
Apple plans to introduce a feature in iOS 27 that lets users select from a range of third-party AI models to power various functions across the operating system. The framework, referred to internally as Extensions, would allow models from installed apps to be invoked by Apple Intelligence features on demand. Bloomberg reported that models from both Google and Anthropic are already being tested in this capacity, representing the two strongest external AI options Apple has evaluated so far.
The feature is expected to span Apple’s major platforms simultaneously, with corresponding availability in iPadOS 27 and macOS 27. Users on iPhones running iOS 27 would be able to visit a new settings panel, select their preferred AI provider, and have that model power capabilities such as the Siri conversational interface, Writing Tools for drafting and editing text, and Image Playground for AI-generated visuals.
This represents a notable departure from Apple’s historically walled-garden approach to core OS features. While the App Store allows third-party apps, the foundational intelligence layer of Apple’s products has until now been controlled entirely by Apple, with the company’s own on-device models and its partnership with OpenAI powering ChatGPT integration in iOS 18. Expanding that integration to multiple competing providers — with user choice built in — is a structural change with significant implications for both the user experience and the competitive dynamics of the AI industry.
Apple’s WWDC 2026, scheduled for later in May, is expected to be the venue at which the company makes a formal announcement, with iOS 27 previewed in detail.
Technical Details
The Extensions framework is designed as an API layer that allows installed third-party apps to expose AI model capabilities to the system. When a user triggers a Writing Tools request or asks Siri a complex question, iOS 27 would route that request to the user’s selected model rather than to Apple’s default on-device AI. The model would need to be installed as part of an app — meaning providers like Anthropic (Claude) and Google (Gemini) would need to have their models accessible through their respective iOS apps.
Apple’s approach appears to draw on its existing Intents and Shortcuts frameworks, which have long allowed third-party apps to expose discrete actions to the system. Extensions would apply similar logic to AI inference, treating an external model as a pluggable capability rather than requiring Apple to fully vertically integrate every AI function it ships.
Privacy considerations loom large over the design. Apple has built its recent AI strategy around on-device processing and its Private Cloud Compute architecture, which it describes as preventing Apple itself from accessing user data sent for cloud inference. Routing data to third-party models introduces a new privacy surface, and Apple will need to clearly communicate what data is shared with external providers and under what conditions — a question that will likely be front and center in the WWDC announcement.
Industry Impact and Reactions
The announcement has significant implications for AI providers competing for distribution. Apple’s iOS installed base is one of the largest and most affluent technology audiences in the world, and becoming the default AI provider inside iOS features represents an extraordinary distribution opportunity. Companies like Anthropic and Google stand to gain not just users but also the implicit endorsement that comes with being featured by Apple.
The competitive dynamics are also notable because they put pressure on OpenAI, which currently has the most prominent iOS AI partnership through its ChatGPT integration in iOS 18. If iOS 27 opens the field to multiple providers, OpenAI’s privileged position becomes less exclusive, and the negotiating leverage shifts toward Apple.
For users, the change promises a meaningfully more personalized AI experience. Someone who relies heavily on Claude for work might set it as their default model for Writing Tools; a developer might prefer Gemini’s coding capabilities for certain tasks. The ability to match AI models to use cases, rather than accepting whatever Apple ships by default, is a form of user agency that the current AI landscape rarely offers at the OS level.
What Comes Next
Apple is expected to formally unveil iOS 27 at WWDC 2026, anticipated in late May or early June. The Extensions framework and the full list of supported AI providers will likely be detailed at that event, along with the developer APIs that third-party model providers will need to implement. A public beta is expected shortly after WWDC, with the full release targeting fall 2026 alongside the iPhone 18.
How Apple handles the privacy and security review of third-party AI models will be closely scrutinized. The App Store review process gives Apple control over what models qualify, and the company is likely to establish rigorous requirements around data handling, transparency, and alignment with Apple’s own usage policies before any model is certified for the Extensions framework.
Conclusion
Apple’s plan to open iOS 27 to third-party AI models is a significant strategic bet that user choice and openness can strengthen rather than weaken the iPhone’s AI position. By letting users pick Claude, Gemini, or other models to power core features, Apple is acknowledging that no single AI provider — including itself — can offer the best experience for every user and every task. It is a pragmatic, potentially transformative move that will reshape the competitive landscape for every major AI company with ambitions in the consumer market.
