Siri AI Comes to Newer Apple Devices Only, With Enhanced Voice Controls on Select Models
Siri AI, a major upgrade in iOS 27 and companion updates, runs only on certain newer Apple devices and in some regions. The ability to customize Siri's voice is limited further to select iPhone, iPad, Mac, and Vision Pro models, according to 9to5Mac.
On iPhone, Siri AI supports iPhone Duo, iPhone 18 Pro and Pro Max, iPhone 17 Pro and Pro Max, iPhone Air, iPhone 17, iPhone 17e, iPhone 16 Pro and Pro Max, iPhone 16 and 16 Plus, iPhone 16e, and iPhone 15 Pro and Pro Max. On iPad, the feature supports iPad Pro models with M1 chip and later, iPad Air models with M1 chip and later, and iPad mini with A17 Pro. On Mac, it supports all models with Apple silicon, including M1 chip and later and A18 Pro chip.
Apple Watch support requires pairing with an AI-supported iPhone. The compatible watches are Apple Watch Series 9 and later, Apple Watch Ultra 2 and later, and Apple Watch SE 3. All Apple Vision Pro models support Siri AI.
Some parts of the Siri AI experience are better on select hardware. Apple says the ability to fully customize the pace and expressivity of Siri AI's voice is available on iPhone 18 Pro, iPhone 18 Pro Max, iPhone Duo, iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air, iPad models with M4 and later and at least 12GB of unified memory, Mac models with M3 and later and at least 12GB of unified memory, and Apple Vision Pro with M5.
Apple attributes the limitation to its most powerful on-device AI model being restricted to newer products, according to 9to5Mac. Users with those models may or may not get faster performance with Siri AI as well.
Editor's Summary
Apple's Siri AI is available only on newer iPhone, iPad, Mac, Apple Watch, and Apple Vision Pro hardware, and only in certain regions, according to 9to5Mac. The broad compatibility list includes many recent devices, but the ability to fully customize Siri AI's voice is limited to select newer models. The report says the restriction follows Apple's decision to keep its most powerful on-device AI model on newer products.
