Apple's New Siri AI Is Ready to Get Personal

At its WWDC 2026 keynote on June 8, Apple introduced a fully rebuilt Siri that holds back-and-forth conversations and takes actions across a user's personal data inside apps. The heaviest cloud reasoning runs on a custom Google Gemini model reported at roughly 1.2 trillion parameters, while simpler tasks stay on Apple's own on-device models. Apple also gave Siri its own stand-alone app, separate from the system assistant, with text and voice input and iCloud-synced history.
