Apple’s new iOS 27 arrives Monday, and its rebuilt Siri now taps Google’s most powerful AI model. The result: a virtual assistant that can track context across more than 20 back-and-forth exchanges, dig through email, juggle calendar entries, and command apps in sequence.
The leap stems from a landmark deal with Google. Apple will reportedly pay around $1 billion yearly for access to Gemini 2.5 Pro, a model with eight times the parameters of Apple’s in-house systems. Yet privacy stays layered. Queries route through Apple’s Private Cloud Compute, so Google never learns who asked what.
The upgrade lands free for every iPhone. The catch: only iPhone 15 Pro and newer hardware get the full Siri AI experience. That covers roughly 150 to 200 million devices, or about three and a half generations. Older iPhones still receive refreshed notifications and stronger child safety tools, but Siri remains unchanged there. Meanwhile, the iPhone 17 lineup, built around a beefier on-device model, hits stores October 23.
Practical demos show the assistant linking inbox to calendar without friction. A user can say, “Find last week’s dental appointment email,” then follow with a second request that triggers actions across two separate apps in one command. On macOS 27, the same intelligence plugs directly into Spotlight, turning the search bar into a task-running console.
But the launch map reveals sharp limits. English works first. French, Japanese, Korean, Portuguese, and Spanish follow in October. Mandarin has no date.
Europe faces a total iPhone and iPad blackout. Apple blames the Digital Markets Act, which would force equal device access for rival assistants. Apple proposed a “Trusted System Agent” compromise. The European Commission rejected it. Macs in the EU still receive Siri AI because macOS falls under different DMA rules. No timeline exists for EU iPhones or iPads.
The real test begins now, in the markets where Siri AI actually turns on.
