Apple lists devices that support Siri AI in iOS 27 and later
Apple detailed the iPhone, iPad, Mac, Apple Watch and Vision Pro models that can run the new Siri AI feature introduced with iOS 27, noting that some functions are limited to the newest hardware.
Apple announced that the Siri AI feature, introduced with iOS 27, is limited to certain newer devices. The compatible iPhone models include the 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. Supported iPad models are the iPad Pro and iPad Air with M1 chips or later, as well as the iPad mini with the A17 Pro chip. All Mac computers equipped with Apple silicon from the M1 chip onward, as well as those with the A18 Pro chip, can run Siri AI. Apple Watch models that can use the feature when paired with a compatible iPhone are the Series 9 and later, Ultra 2 and later, and the third-generation SE. The Apple Vision Pro also supports Siri AI.
"The ability to fully customize the pace and expressivity of Siri AI’s voice is only available on select hardware," Apple said, adding that this capability is limited to iPhone 18 Pro, iPhone 18 Pro Max, iPhone Duo, iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air, iPad models with M4 chips and at least 12 GB of unified memory, Mac models with M3 chips and at least 12 GB of unified memory, and Apple Vision Pro with M5.
Apple noted that the restriction is due to the most powerful on-device AI model being available only on newer products, which may also affect performance speed.
