iOS 27

Apple has released iOS 27 with a rebuilt Siri powered by large language models, plus more than 20 new Apple Intelligence features spanning Photos, Messages, Mail, Safari, and system-wide tools like proofreading and Call Context.

Journalist David Pogue ran 125 test prompts against the new Siri AI in iOS 27, finding it successfully handled cross-app queries, contextual follow-ups, and complex multi-step requests. Failures were limited to tasks requiring third-party app updates, such as Venmo payments.

Apple has released a beta of its rebuilt Siri, now powered by Google's Gemini models, as part of iOS 27 and related 2027 software updates. The assistant reads screen content and personal context but won't launch in the EU or China due to regulatory concerns.

iOS 27, released alongside the public launch of Siri AI, adds a new setup prompt asking users to opt in to sharing audio and text data to improve Apple's Foundation Models. The data collected is unchanged from before, but Apple will now also use it to train its foundation models rather than only Siri and Dictation.

Apple released iOS 27 on Monday, introducing a beta version of its redesigned Siri AI assistant ahead of iPhone 18 availability this week. The new Siri uses large language models to search personal data like texts and calendars, but requires opt-in and isn't yet available in the EU or China.

Developer PDFU discovered private hooks in iOS 27 and macOS 27 code that let apps register as Siri Extensions, potentially allowing users to swap Siri AI's backend for Claude, ChatGPT, or other third-party models. The feature is present in code but not currently enabled.

Apple's overhauled Siri AI launches next week as part of iOS 27, with early hands-on use showing it can search personal data—emails, notes, photos—to answer specific questions. The upgrade marks Apple's most significant Siri update to date, according to 9to5Mac.

Apple released the iOS 27 public beta, making its AI-powered Siri overhaul available to all users for the first time beyond developers. The assistant leverages Apple Foundation Models built in collaboration with Google Gemini, running on-device with Private Cloud Compute across Apple's 2.5 billion active devices.

Apple's iOS 27 beta introduces a standalone Siri app with a chatbot interface that allows users to switch between Siri and ChatGPT by long-pressing the input field. Conversation context does not transfer when switching providers, and the app defaults back to Siri when reopened.

Apple's senior vice president Craig Federighi disclosed that iOS 27's Siri AI uses a family of third-generation Apple Foundation Models trained with outputs from Google's Gemini frontier models. The most capable model, AFM Cloud Pro, runs on Nvidia GPUs in Google's cloud infrastructure while maintaining Apple's Private Cloud Compute privacy architecture.

Apple will allow iPhone users to select from multiple third-party AI models to power system features in iOS 27, launching later this year. The feature, called 'Extensions,' will integrate models from Google and Anthropic into Siri, Writing Tools, Image Playground, and other Apple Intelligence features.

Apple plans to introduce an Extensions system in iOS 27, iPadOS 27, and macOS 27 that will allow users to select third-party AI models for generative AI tasks. AI companies can opt in through App Store programs to power Apple Intelligence features including Siri, Writing Tools, and Image Playground.

Apple will allow iOS 27 users to select third-party AI models from companies like Google and Anthropic to power Siri, Writing Tools, and other Apple Intelligence features. The new "Extensions" system lets users choose which AI model responds to queries, with support for custom Siri voices per model.
