Apple's revamped Siri is live in the iOS 27 developer beta, and for the first time the assistant is built on a model partly powered by Google's Gemini. The new Siri AI indexes a user's photos, messages, and emails on-device, sits inside the iPhone search bar, and answers conversationally with bite-sized replies rather than long monologues. Apple confirmed the wider public rollout for later this year at WWDC 2026.
The Gemini deal is the structural change. Google's model now helps power Apple Intelligence, the layer underneath Siri, replacing the limited in-house stack that defined the previous generation. The shift gives Siri the kind of natural-language fluency that ChatGPT and Claude users have had for two years, while Apple keeps the assistant routed through its own Private Cloud Compute for inference on harder queries.
Hardware support is tightly tiered. Only three devices — the iPhone Air, iPhone 17 Pro, and iPhone 17 Max — get every Siri AI feature, including the broader set of voice options. Every iPhone 16 and iPhone 17 model can run the new Siri at a lower feature tier. Among older phones, only the iPhone 15 Pro and Pro Max are compatible at all; everything earlier is shut out.
Key facts
- 01Siri AI ships in the iOS 27 developer beta now and rolls out to the public later in 2026.
- 02Google's Gemini powers the underlying Apple Intelligence model behind the new Siri.
- 03Only the iPhone Air, iPhone 17 Pro, and iPhone 17 Max get the full Siri AI feature set, including more voice options.
- 04Every iPhone 16 and iPhone 17 model can run Siri AI; among older devices, only the iPhone 15 Pro and Pro Max are compatible.
- 05Initial on-device indexing of photos, messages, and emails took roughly one week on an iPhone 16 Pro Max running the beta.
The on-device indexing requirement is non-trivial. A Wired hands-on running the developer beta on an iPhone 16 Pro Max reported the phone took roughly one week to fully index its content before personalization features became reliable. That indexing is what lets Siri answer prompts like "find photos from the last time I went to Costa Rica" by surfacing images from two years ago, or pull unfinished plans out of recent message threads when asked "what should I do today."
Apple repeatedly emphasized privacy framing at WWDC 2026. Under Private Cloud Compute, Apple says it does not store user data and only references it when Siri is asked a question. Users who do not want the assistant can disable Siri AI in settings, the same opt-out path that existed for the prior generation. The pitch is that the personalization comes from data that never leaves Apple's controlled compute envelope.
In practice, the assistant is now stitched across the operating system rather than living in its own silo. Siri pops up from a swipe-down on the home screen, conversations persist in a dedicated app for follow-ups, and the assistant interoperates with non-Apple services — a draft text, for example, will prompt the user to choose between Apple's Messages and Meta's Messenger before sending. The camera app feeds Siri visual context: point the camera at a scene and the assistant returns information without an explicit prompt.
The Wired tester walked through San Francisco using Siri AI as a tour guide. It recommended a brunch spot called Eats in the Inner Richmond when asked for fluffy pancakes near the Golden Gate Bridge, surfaced hiking options in the Presidio and the Marin Headlands, answered seasonal questions about the sea lions at Fisherman's Wharf, and pulled context from Wikipedia and the official Fisherman's Wharf site with citations to click through. Selfie automation, dictation, and contact lookup worked on retry.
Rough edges remain. Shown a photo of a foggy trail near the Golden Gate Bridge, Siri identified the Monterey cypress trees but attributed them to the Cypress Tree Tunnel at Point Reyes National Seashore — an hour's drive from where the photo was taken. A hot-pot photo query also surfaced unrelated hot-tub vacation pictures. Dictation included literal phrases like "with a" before an emoji, once produced a school emoji instead of a skull, and once asked whether to also send a message to an unrelated contact. These are the kinds of beta bugs that get patched between developer seeds and public release.
The competitive read is more interesting than the bugs. Apple has spent two years watching OpenAI's ChatGPT and Anthropic's Claude build standalone app ecosystems on iOS while Siri stagnated. By embedding a Gemini-backed assistant directly into search, camera, and messaging — rather than asking users to open a separate app — Apple is betting that distribution beats model quality. There are roughly a billion active iPhones; even partial adoption is a larger user base than any standalone assistant has reached.
The Gemini partnership also reframes Google's position. Google has spent the year arguing Gemini is competitive with the frontier on benchmarks; having it power the default assistant on the iPhone is a far stronger commercial proof point than any leaderboard. It also raises the obvious question of what Apple pays Google for the integration, and whether the arrangement parallels the multibillion-dollar Safari search default that US antitrust regulators are already targeting.
For Apple, the stakes are about whether Siri AI changes daily iPhone behavior. The previous Siri was a punchline; the new one is a real assistant with photo recall, message awareness, and cross-app automation, gated to the newest hardware in a way that conveniently aligns with the upgrade cycle. If even a fraction of iPhone 17 buyers rewire their habits around voice and on-device search, Apple converts a software embarrassment into the most-used AI assistant in the world — and pulls a meaningful share of consumer AI engagement away from the standalone chatbot apps in the process.
