At WWDC 2026 today, Tim Cook’s final keynote before he hands the company to John Ternus in September, Apple unveiled iOS 27. The headline feature is a complete rebuild of Siri. But the most revealing detail isn’t what the new assistant does; it’s where its intelligence comes from.

Apple’s new Siri is powered by Google’s Gemini. And for the questions it can’t answer itself, it can hand you off to ChatGPT or Claude.

For a company that has long preferred to build its core technology in-house, that’s a notable strategic shift and a smart one. Here’s a clear look at what iOS 27 actually includes, and what the decisions behind it tell us about where Apple is heading.

The headline: Siri, rebuilt

After a difficult Apple Intelligence rollout in iOS 26, Apple has rebuilt its assistant from the ground up and rebranded it Siri AI. The changes are substantial:

Here’s what actually changes for you:

• Siri is now a real chatbot: There’s a dedicated Siri app where you can hold actual back-and-forth conversations, scroll through your chat history, and attach a photo so it understands what you’re talking about the same way you’d use ChatGPT or Claude today.
• A new “Search or Ask” gesture: Swipe down from the top of your screen, and you land in a single panel where you can search your phone, fire off a shortcut, or ask a complex question. One swipe, one place.
• Siri lives in the Dynamic Island now: Say “Siri” or hold the power button, and it pops up with a new animation, instead of taking over your whole screen.
• Multi-step commands in one breath: You can chain requests, “find the photos from Lagos last month, make an album, and text it to my brother”, and it’s meant to follow the whole thread.
• The camera gets smart: Visual Intelligence has been rebranded to Siri Mode and pushed front-and-centre in the Camera app. Point it at a nutrition label, a business card, a poster, and it reads the world for you. If that sounds like Google Lens, that’s because it now basically is.

It’s a significant leap for an assistant who had fallen behind its rivals. The more interesting story is the strategy that made it possible.

The strategy: distribution over models

Under the hood, Siri AI is built on Google’s Gemini, following a deal the two companies struck earlier this year. The new “Search or Ask” panel can also route more demanding questions to third-party models ChatGPT, Claude, and Gemini, letting users choose which one they prefer.

This is a meaningful change in approach for Apple, and the logic behind it is worth understanding. Rather than spend more years trying to build the single best AI model alone, Apple has positioned the iPhone as a neutral gateway to the best models available, whoever builds them. It’s a recognition that the competitive advantage may lie less in owning the smartest model and more in owning the device and the experience that billions of people reach for first.

It also raises a fair question on privacy, given Apple’s strong public stance on the issue. The company says Siri history syncs through its Private Compute system rather than living on third-party servers, a detail worth watching as more details emerge and the feature reaches users.

The quieter story: a focus on getting the basics right

Beyond Siri, iOS 27 is being compared to Mac OS X Snow Leopard, the 2009 release remembered for adding a few new features and refining what already existed. After iOS 26’s bugs, that emphasis is welcome:

• Better performance on older iPhones, thanks to a new CPU scheduler aimed at keeping ageing devices responsive.
• Improved battery life is a likely benefit of the optimisation focus.
• A rebuilt search index that makes Spotlight more accurate across the system, with a smarter ranking system in Mail.
• A Liquid Glass transparency slider, giving users control over the design introduced in iOS 26, plus sharper, more refined icons.

For users, an update focused on reliability over novelty is often the most valuable kind.

The features that matter day to day

• Messages gains continuous sending of photos and texts, automatic retries for failed messages, and cleaner syncing across devices.
• FaceTime adds dual-camera support and better call quality on weaker connections, useful for anyone on variable mobile data.
• Photos now supports iCloud Shared Albums with Android and Windows users, so shared albums work across platforms.
• Apple Wallet lets you create your own digital passes for physical items like membership cards.
• New keyboards and languages, including Afrikaans, Xhosa, and Zulu. It’s a positive step for African language support, though widely spoken West African languages such as Hausa, Yoruba, and Igbo are not yet included in an area with clear room to grow.

Release timeline and compatibility

• Developer beta: available now, following the keynote.
• Public beta: expected in July.
• Full release: fall 2026, likely alongside the next iPhone lineup in September.
• Compatibility: any iPhone that runs iOS 26 will run iOS 27 (iPhone 11 and second-generation SE and newer).

One thing to keep in mind: the new Siri AI may launch with a “beta” label and possibly a waitlist, mirroring how Apple introduced Apple Intelligence in 2024. Some features may roll out gradually rather than all at once.

The takeaway

iOS 27 tells two stories at the same time. One is a strategic pivot: rather than win the AI race alone, Apple has chosen to make the iPhone the best place to access whichever AI is strongest, its own, or a partner’s. The other is a return to fundamentals, with a release built around speed, stability, and reliability after a rocky year.

Both point to a more pragmatic Apple, one focused less on doing everything itself and more on delivering the best overall experience to the user. For anyone who depends on their iPhone every day, that may prove to be the more important shift.
