Apple ships iOS 27 on September 14, launching an all-new Siri AI assistant
Apple began rolling out iOS 27 on September 14, alongside matching updates to iPadOS, macOS, and watchOS. The headline feature is an all-new "Siri AI," delivered as its own dedicated app and built on large language models, able to search a user's texts, emails, and calendar for semantic answers and to take actions across supporting apps, with on-screen awareness and the ability to handle follow-up questions — widely seen as the long-delayed assistant upgrade Apple first promised with Apple Intelligence back in 2024. iOS 27 itself supports devices back to the iPhone 11 and second-generation iPhone SE, but the full Siri AI experience requires an iPhone 15 Pro or newer.
