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

Apple is planning to let users choose their preferred AI model for Apple Intelligence features in upcoming operating systems (iOS 27, iPadOS 27, and macOS 27) expected this fall. Third-party AI models, called "Extensions," will be able to power features like Siri, Writing Tools, and Image Playground across the system. Users will also be able to assign different Siri voices to different AI models.
