Apple iOS 27 Extensions Opens Siri to Third-Party AI Models
Apple will let iOS 27 users choose from third-party AI models like Claude, Gemini, and ChatGPT to power Siri, Writing Tools, and Image Playground. The new 'Extensions' framework turns the iPhone into a neutral AI platform where users select their preferred model in Settings, ending ChatGPT's de facto exclusivity since iOS 18.2.
The bottom line: Marketing teams using iOS-first customer journeys need to prepare for multi-model AI interactions where brand recommendations could come from any LLM the user selects.
