Revamped Siri in iOS 27 to use Google Gemini under the hood with auto-deleting chats

This confirms longstanding rumors that Apple Intelligence's most ambitious agentic tier will be Gemini-powered rather than first-party — a major reversal of Apple's historical posture and a coup for Google days before I/O. The standalone Siri app is the bigger product change: instead of a system-level invocation, Siri becomes an addressable app/agent that can act across Mail, Notes, Calendar, and third-party surfaces via Apple's expanded App Intents framework.

The auto-deletion feature (30 days or 1 year, user-selectable) is Apple's privacy-led counter-narrative to ChatGPT's persistent memory and Gemini's account-linked history. Gizmodo and Mark Gurman both note the framing risks: Private Cloud Compute remains opaque on what Gemini sees, and Apple has not detailed the data boundary between on-device, PCC, and Google's infrastructure.

Competitive lens: Apple is effectively conceding the model-quality race while leveraging distribution (2B+ active devices) as the lever. Google gets default-status AI placement on the world's most profitable platform — the kind of deal that historically has paid Apple $20B+/year. Financial terms haven't surfaced; this is the number to watch.

Developer community is split — privacy fans welcome auto-delete, but iOS developer forums are nervous about the App Intents surface area and whether third-party apps get equal Siri-agent access or whether Apple's own apps stay privileged. WWDC opening keynote (June 8) is the moment of truth.
