Overview
- Siri was torn down and rebuilt on new foundation models after Apple concluded a 2025 incremental upgrade did not meet its product vision, company engineers told the press.
- The overhauled assistant is a standalone app that accepts multimodal input and is designed with privacy controls built into its architecture.
- Apple demonstrated the new Siri running on real devices at WWDC and has released iOS 27 developer betas so third‑party developers can start testing integrations.
- A public beta is expected soon and a wider consumer launch will follow in stages, with some features limited by device capability, language and region.
- The rebuild uses a hybrid approach that runs smaller models on devices and relies on private cloud for heavier work, a design that aims to balance capability, speed and user privacy.
