Apple released iOS 27 to compatible iPhones on 14 September (US time), headlined by the delayed Siri AI overhaul the company has been working toward S¹. But the new Siri arrives as a beta, and only for devices set to English A².
My read: This is the first time I've seen Apple ship a headline AI feature as an explicit beta inside a major numbered OS release. The delay already cost them credibility, and launching English-only in September with five languages promised for October tells me the model is still being tuned. I'd hold off judging Siri AI until the October expansion lands and we see whether non-English performance matches what Apple has shown in English.
Siri AI is the lead feature across all four of Apple's simultaneous platform releases, according to The Verge: iOS 27, watchOS 27, iPadOS 27, and visionOS 27 S¹. Apple says support for French, Japanese, Korean, Portuguese, and Spanish will follow in October S¹. Until then, anyone running their device in another language gets the old Siri.
The update lands just ahead of the iPhone 18 Pro release S¹. iOS 27 itself runs on iPhone 11 and iPhone SE (2nd generation) and later S¹, but Siri AI does not: Apple lists iPhone 15 Pro, iPhone 15 Pro Max, the iPhone 16 range or later, iPhone Air and iPhone Duo as the supported phones A². Siri AI will not be available initially in the EU on iPhone, iPad or Apple Watch, it is not available in China, and it is not offered to users under 13 A².
What else changed across the four updates
Beyond Siri, iOS 27 adds a Liquid Glass opacity slider that lets users choose between a clearer interface and a frosted look, redesigned app icons with subtle colour shifts, extra large widgets, and separate volume controls for ringtones, alarms, timers, alerts, and system sounds S¹.
watchOS 27 brings new Workout Buddy features, a new tap gesture, Liquid Glass refinements, new Smart Stack suggestions, and an improved Find My app S¹. iPadOS 27 speeds up browsing and file transfers to external drives, and smooths the handoff between Wi-Fi and mobile data S¹. visionOS 27 includes the Siri AI overhaul alongside eye-based notification previews, Control Center UI updates, Wi-Fi improvements, and the ability to use photographed panoramas as immersive environments S¹.
The October language expansion is the next checkpoint. Anyone with a supported iPhone set to one of those five languages can test whether Apple's delayed promise holds on schedule A².
