Apple could let you pick a favorite AI model in iOS 27

According to Bloomberg’s Mark Gurman, Apple’s next major OS updates — iOS 27, iPadOS 27, and macOS 27 — could introduce a feature called ‘Extensions’ that lets users choose a preferred AI model to power Apple Intelligence system-wide. This would go beyond the current ChatGPT-only integration, allowing third-party models from providers like Google and Anthropic to handle tasks like Siri queries, Writing Tools, and Image Playground. Users would install a compatible AI app from the App Store, then set it as their default in the Settings app. Gurman notes that different Siri voices could even be assigned to different models, giving users granular control over their AI assistant’s personality.

The move signals Apple’s shift toward a more open AI ecosystem, potentially avoiding reliance on a single partner. Internal testing already includes Google’s models (which also back Apple’s upcoming Siri revamp) and Anthropic’s Claude. By letting developers opt in via their App Store apps, Apple could turn its devices into a platform for multiple AI assistants, each with distinct capabilities. This could reshape how professionals use AI on Apple hardware — choosing the best model for writing, coding, or image generation without leaving the OS.
