Overview
- Apple published iOS 27, macOS 27 Golden Gate, watchOS 27, visionOS 27 and tvOS 27 and began the staged public rollout of Siri AI as an opt‑in beta on Monday.
- Siri AI uses a hybrid model that runs smaller Apple Foundation Models on device for routine requests and routes complex queries to cloud inference via Apple’s Private Cloud Compute, which relies on partners such as Google Cloud, Nvidia and Intel.
- The assistant indexes personal data from native apps like Messages, Mail, Photos and Calendar to provide context and can act on that data through a new Siri app that logs conversations and syncs them with end‑to‑end protections.
- Apple is gating full Apple Intelligence by hardware and region: recent iPhones and newer Watch chips are required for some features, Apple said Siri AI won’t initially be available in China or broadly in the EU, though Vision Pro users in the EU have reported access.
- Some cloud‑based Siri features are subject to daily server usage limits and Apple plans to offer expanded quotas for a fee, a move that could shape how often users rely on on‑server capabilities versus on‑device processing.
