Apple to Let Users Choose AI Models in iOS 27
Apple is preparing a change in iOS 27 that will let users choose which AI model powers Apple Intelligence. Internally called "Extensions," the feature will allow third-party models system-wide access to Apple AI features — from Siri to writing tools and image generation. Bloomberg reporting and Mark Gurman’s sources indicate Apple is testing integrations with Google’s Gemini and Anthropic’s Claude. The functionality is planned for iPhones, iPads and Macs; Apple may preview it at WWDC on 2026-06-08, with iOS 27 expected to ship in the autumn alongside the iPhone 18.
A major platform (Apple) enabling third-party AI models at the OS level could reshape assistant capabilities, vendor partnerships (e.g., Google, Anthropic), and how on-device AI features integrate with the app ecosystem.

Apple to Let Users Swap AI Models in iOS 27
Apple plans to let iPhone users choose from multiple third‑party AI models that can run on‑device when iOS 27 ships later in 2026. According to a Bloomberg report cited by TechCrunch, the feature—internally called “Extensions”—would let installed apps expose generative AI capabilities to Apple Intelligence features such as Siri, Writing Tools and Image Playground. The capability is expected to arrive across iOS 27, iPadOS 27 and macOS 27; Google and Anthropic models are reported to be in testing and the status of ChatGPT is unclear. The move is part of Apple’s strategy to deliver AI via devices rather than large cloud services, and comes amid leadership change as Tim Cook prepares to step down and John Ternus takes on broader company responsibilities.
Apple opens Siri to multiple external AI models
According to Bloomberg reporter Mark Gurman, Apple will let Siri access and mediate multiple external AI models starting with iOS 27. The company is building a modular system (via “Extensions”) that lets users enable AI apps through Settings and choose which model to interact with; the new Siri architecture is expected to be unveiled at WWDC and roll out with iOS 27, iPadOS 27 and macOS. Apple previously integrated OpenAI/ChatGPT as a fast interim step and plans to keep partnerships such as with Google. The move could increase App Store transactions and subscription monetization for Apple, though regulatory rules like the Digital Markets Act limit how uniformly Apple can take commissions. Competitors including Google (Gemini) and Anthropic (Claude) are adding features to transfer or import user memory/context between AI tools to reduce switching friction.
Apple's Siri to Use Google's Gemini
Rumors converge around Apple’s plan to overhaul Siri by powering a new version with Google’s Gemini AI. The refreshed Siri is expected to ship with iOS 26.4, with a launch possibly in spring 2026. Apple reportedly evaluated competing AI systems from OpenAI (ChatGPT) and Anthropic (Claude), but Bloomberg and Apple-connected sources indicate Google won the race, and a Gemini model tailored for Siri is already in testing on Apple’s servers. The negotiations reportedly include terms for deeper Gemini integration and reflect long-standing Google-Apple arrangements, including Google’s past payments to be the default iPhone search engine. Beyond Siri, Apple pursues broader AI ambitions, including an AI search strategy and a shift to Apple Ads, with ads in Apple Maps anticipated in 2026 and a gradual rollout of Apple Intelligence in Germany since 2025. Deployment pace within Apple’s ecosystem remains cautious.
