Apple ships iOS 27 on September 14, launching an all-new Siri AI assistant
Apple began rolling out iOS 27 on September 14, headlined by an all-new "Siri AI" delivered as its own app, built on large language models and able to search a user's texts, emails and calendar for answers and take actions across supporting apps. iOS 27 supports devices back to the iPhone 11, though the full Siri AI experience requires an iPhone 15 Pro or newer.
