Apple launched the iOS 27 public beta, giving everyday users access to Siri AI for the first time beyond developers. The revamped voice assistant leverages Apple Intelligence and Foundation Models to access emails, photos, and messages while providing contextual responses. With 2.5 billion active Apple devices worldwide, this represents the largest test of Apple's answer to ChatGPT and Gemini.

Apple Opens Siri AI to Public Testing

Apple has released the iOS 27 public beta, marking the first time the company's completely redesigned Siri AI is available to everyday users beyond developers

With approximately 2.5 billion active devices worldwide, even a fraction of users installing the iOS 27 public beta will constitute the largest test of Apple's redesigned assistant

1

. The update was officially announced at Apple's Worldwide Developers Conference in June and transforms the aging assistant into a more capable tool that can access on-device information including emails, photos, and messages

Deep Integration and New Access Points

The new Siri AI demonstrates multimodal integration across Apple's entire ecosystem. Users can access it through traditional methods like saying "Hey Siri" or pressing the side button, as well as new options including swiping down from the Dynamic Island

. The assistant is also integrated into Spotlight, Apple's built-in search engine tool, making it more powerful for answering almost any question

.

For the first time, Siri has its own standalone Siri app that functions like a chatbot, though accessing it via the app may seem unnecessary given how deeply integrated it is throughout the iPhone

. The app serves primarily as an interaction log where users can track past conversations or revisit previous threads

2

. Users can adjust how long conversations are stored by navigating to Settings and selecting between forever, one year, or 30 days

Personal Context Features and Indexing

One of Siri AI's most significant advantages over competitors is its access to personal context features through on-device information. "Siri AI has access to the kind of context that things like ChatGPT and Claude can't easily have, because Siri is cooked into the operating system," says Josh Clark, principal at digital-design agency Big Medium

.

However, users must wait for an indexing process to complete before experiencing full Siri AI capabilities

. The iPhone builds a searchable, on-device database during this process, which can take over a week depending on the device, storage, and software version

2

. Apple recommends keeping devices plugged in to charge longer to speed up this process

4

.

Once indexing completes, the assistant can pull data from across the device to deliver contextual responses. During testing, Siri AI successfully gathered information from text messages to highlight upcoming deliveries and events, while also reviewing calendar appointments

. In another test, when asked to show photos from Paris, Siri found images from a 2024 trip, and when asked about Japan photos, it displayed images from a San Francisco sake bar while noting it couldn't find any from Japan itself

Apple Intelligence and Foundation Models

Under the hood, Siri AI leverages Apple Intelligence, including Apple's new Foundation Models that run on the device and use Private Cloud Compute

1

. Apple built its Foundation Models in collaboration with Google and its Gemini model, but these are not simply rebranded versions of Gemini

1

. Instead, Apple's models were built specifically for Apple Silicon using proprietary data and distilled Gemini—a process that uses Gemini to create smaller, highly efficient models built into iOS and other Apple software

1

. Private Cloud Compute ensures users' personal data isn't stored or accessible to Apple

.

Practical Applications and Limitations

Early testing revealed diverse Siri AI capabilities for everyday tasks. The assistant successfully found specific photos in Photo Library, summarized group texts, added appointments sent via text to calendars, and looked up nutritional information about items in camera view

. It also handled web-based questions about local events and news more effectively than previous versions

Nabila Popal, senior research director at International Data Corporation, notes: "They've integrated it across the entire ecosystem, so you can access Siri AI no matter where you are on the device. The accessibility of Siri AI and its integration across the operating system were really well done"

2

.

However, the developer beta showed limitations. Siri sometimes threw error messages or got confused, such as searching contacts when asked about news regarding Iran

1

. Currently, if information resides in third-party app platforms like Gmail, WhatsApp, or Google Photos, Siri cannot access it

3

. Third-party app integration will depend on developers adding Siri AI support to their applications

3

.

The assistant also lacks a memory feature to store user preferences, meaning users must repeatedly remind Siri about details like dietary restrictions when asking for recipes

2

. Apple is expected to iterate and add new capabilities over time

.

How to Access the Beta

To try the new Siri AI, users need an iPhone 15 Pro or later for the full experience

5

. After enrolling in the Apple Beta Software Program, users must install iOS 27 Public Beta through Settings, then join a waitlist for Siri AI access

5

. During the developer beta, this waitlist took nearly two weeks for some users

5

. Siri AI is currently only available in English and is not available in the E.U.

5

.

The upgraded Siri is available across all Apple products, including iPad, Mac, Apple Watch, CarPlay, AirPods, Apple TV, and Vision Pro

1

. iOS 27 also introduces improved dictation accuracy for handling punctuation and formatting automatically, along with enhanced writing tools that can mimic users' typical communication styles in Mail and Messages apps

4

.

The public launch of iOS 27 is expected in September, with developer betas this year proving fairly stable
