Apple released Siri AI as a dedicated iOS 27 app built on Google’s Gemini model.
At WWDC 2026 the company announced Siri AI, the first major rewrite of its voice assistant in 15 years. The new service runs as a separate app bundled with iOS 27, which ships in September 2026. Apple says the app runs on a custom‑tuned version of Google’s Gemini large‑language model and adds a three‑tier privacy stack that processes speech locally, encrypts data in transit, and stores only anonymised snippets for optional improvement.
The move matters because it ends Siri’s tightly‑integrated role in iOS and gives developers a clear API surface while leaning on Google’s AI research rather than Apple’s own. The privacy layers also signal Apple’s attempt to differentiate its assistant in a market where data handling is under scrutiny.
In practice, users will have to download the Siri AI app after the iOS upgrade, and the rollout will start with a beta for developers before a public release later in the fall.
