Apple’s Siri AI Gets Its Biggest Overhaul Yet, Now Open to Everyone in the iOS 27 Public Beta
The Biggest Apple Siri Overhaul Ever Goes Public
If you’ve been waiting to try Apple’s redesigned Siri without messing around with a developer beta, that wait is over. On July 13, Apple released the iOS 27 public beta, opening up its AI-powered assistant to any iPhone owner willing to install pre-release software — no developer account required.
Until now, the new Siri had only been available to registered developers since Apple unveiled it at its Worldwide Developers Conference in June. That’s changed. With an estimated 2.5 billion active Apple devices in the world, even a modest beta adoption rate makes this the largest real-world test yet of Apple’s answer to ChatGPT, Gemini, and Claude.
What’s New in Siri AI
The version of Siri arriving in iOS 27 is a substantial departure from the voice assistant iPhone users have known for over a decade. It’s built to hold ongoing, natural conversations, understand follow-up questions without needing the original context repeated, and respond to whatever is currently on your screen.
Practically, that means Siri can now:
- Search across personal data in apps like Mail, Messages, Notes, Reminders, and Calendar
- Summarize a group text thread
- Add an appointment mentioned in a text message directly to your calendar
- Identify food in your camera view and pull up nutritional information
- Answer general-knowledge questions you’d normally have to search the web for, such as when a local event is happening or what’s in the news
- Take actions inside supported apps, like editing a message you just sent or adding a song to a playlist
Responses now surface through the Dynamic Island, and a new standalone Siri app keeps a running conversation history, synced privately through iCloud. Siri can be summoned by voice, by pressing the side button, by swiping down from the Dynamic Island, or through Spotlight search.
The Technology Behind It
Under the hood, Apple built Siri AI in partnership with Google. Rather than running Google’s Gemini model directly, Apple used it as a starting point for a process called distillation — training smaller, more efficient models on Apple Silicon using Apple’s own proprietary data, with Gemini serving as the teacher model. Apple’s Private Cloud Compute infrastructure is designed to ensure personal data used by Siri isn’t stored or accessed by Apple itself, though some reporting indicates Apple has begun routing certain cloud-based Siri queries through Nvidia hardware hosted on Google Cloud, after finding Gemini ran too slowly on Apple’s own servers.
Not Perfect Yet
Early testers of the developer beta reported a rockier experience than the polished demo Apple showed at WWDC. Siri occasionally threw error messages or misunderstood requests — one widely shared example involved a tester asking for recent news about Iran, only to have Siri search their contacts for a person by that name instead.
Even so, this year’s developer betas have reportedly been more stable than in past cycles, which is part of why Apple appears comfortable pushing the assistant out to public testers now rather than waiting for the fall release.
How to Try It
Installing the public beta doesn’t automatically turn on Siri AI. Here’s what’s involved:
- Back up your iPhone to iCloud or a computer before installing any beta software.
- Visit the Apple Beta Software Program website and sign in with your Apple Account.
- On your iPhone, go to Settings > General > Software Update > Beta Updates and select the iOS 27 Public Beta.
- Return to Software Update and tap Update Now.
- Once updated, enable Apple Intelligence in Settings, then go to Siri settings and tap “Try the new Siri (Beta)” to join a waitlist.
Access isn’t necessarily instant — approval can take anywhere from a single day to roughly five to ten days, with developer program members typically moving through faster.
Siri AI requires an Apple Intelligence-compatible device, starting with the iPhone 15 Pro and continuing through the iPhone 17 lineup and iPhone Air. Some advanced features, including expressive voice controls, are limited to the iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air. The feature also launches with support for select English variants only and won’t be available in the European Union right away.
Beyond the iPhone
iOS 27 isn’t the only beta Apple released this week. Public betas also went out for iPadOS 27, macOS 27 (internally code-named Golden Gate), watchOS 27, tvOS 27, and visionOS 27 — all bringing some version of the new Siri AI to their respective platforms. On the Mac, Siri can be summoned from Spotlight to analyze what’s on screen or assist with writing. On the Apple Watch, it’s positioned as a hands-free helper during workouts or while on the move.
iOS 27 also brings changes unrelated to Siri, including a redesigned Screen Time experience, refinements to the Liquid Glass visual style introduced last year, new Photos editing tools like Clean Up and Spatial Reframing, and performance improvements Apple says can make apps launch up to 30% faster.
Should You Install It?
Beta software always comes with tradeoffs — potential bugs, reduced battery life, and compatibility issues with third-party or work apps are all possibilities. Apple recommends installing pre-release software on a secondary device where practical, and always backing up beforehand.
That said, if this year’s betas hold up to their early reputation for stability, the iOS 27 public beta may be one of the more comfortable ones to jump into — especially for anyone curious to see what Apple’s biggest Siri redesign in over a decade actually feels like in daily use. The finished version, including the fully polished Siri AI, is expected to ship publicly this September.
