iPhone 17's 8GB Limit Costs It These Two Siri AI Features in iOS 27
MacRumors • • technology
Key Points:
- Apple’s latest on-device AI model, requiring 12GB of unified memory, powers more expressive Siri voices and significantly improved systemwide dictation accuracy, including automatic punctuation and formatting.
- The 12GB memory requirement limits these enhanced features to higher-end devices like the iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air, iPads with M4 chip or later, Macs with M3 or later, and Apple Vision Pro with M5, excluding the base iPhone 17 which has only 8GB.
- Other Siri AI features such as personal context, onscreen awareness, web answers, and the dedicated Siri app run on a broader set of devices, including the iPhone 15 Pro, iPhone 16 series, and iPhone 17.
- Base iPhone 17 users will receive the new chatbot-style Siri assistant in iOS 27 but with older voice options and less advanced dictation capabilities, which may affect users who frequently rely on dictation.
- iOS 27 is currently in developer beta, with a public beta expected next month and full release planned for the fall.
