Apple Rebuilds Siri With Gemini-Powered Action Surface

Apple rebuilt its Siri assistant on Google's Gemini, using a custom 1.2-trillion-parameter model and paying Google approximately $1 billion annually, according to independent reports. The new Siri AI, unveiled at WWDC, features on-screen awareness and the ability to take actions across apps, including editing messages and extracting calendar events from email, with a release slated for later this year. The upgrade raises operational risks from hallucinations and erroneous actions, even as Apple emphasizes privacy protections.

Apple Rebuilds Siri With Gemini-Powered Action Surface At WWDC and on its product page, Apple unveiled Siri AI , a rebuilt assistant with on-screen awareness, broader access to on-device context, and the ability to take actions across apps; Apple presents these features as part of Apple Intelligence , with new capabilities arriving "coming this fall" and "Siri AI coming in English later this year" Apple . Reporting by multiple outlets shows hands-on testers were able to ask Siri to extract calendar events from email, edit text across apps, and add reminders The Verge; Wirecutter . Independent reporting claims Apple rebuilt Siri on Google's Gemini, reportedly a custom 1.2-trillion-parameter model and that Apple pays Google on the order of $1 billion per year for access Cringely; Wired reporting . Editorial analysis: granting an assistant the ability to act inside apps increases operational risk from hallucinations and bad actions, even if privacy protections are emphasized. What happened Apple revealed a rebuilt assistant, branded Siri AI , at WWDC and on its product page for Apple Intelligence . Per Apple's product page and WWDC demos, Siri AI will have on-screen visual awareness , access to on-device context across Photos, Messages, Mail, Calendar, and the ability to take actions inside third-party and first-party apps such as editing messages, adding calendar events, and managing Safari tabs Apple; Wirecutter . Apple lists the release timeframe as " coming this fall " and "Siri AI coming in English later this year" Apple . The Verge and other hands-on reporters verified several of these features in early builds, including extracting events from email and composing or editing across apps The Verge; MacRumors; TechRadar . Technical details Reporting from Cringely and coverage in Wired state that Apple's new assistant is rebuilt on Google's Gemini, with Cringely claiming a reportedly custom 1.2-trillion-parameter variant and an annual payment to Google on the order of $1 billion . These vendor-relationship and model-size claims are reported by those outlets and are not stated on Apple's public product page; Apple's marketing materials instead emphasize a combination of on-device context plus broader world knowledge via cloud services Cringely; Wired; Apple . Industry context Editorial analysis: Companies that enable assistants to act inside user workflows enlarge the attack surface for operational errors. In previous, chat-only deployments a hallucination typically costs time and a correction. When an assistant can perform transactions, edit content, or move items between apps, hallucinations can produce tangible errors: mis-sent messages, incorrect calendar entries, or undesired file deletions. Industry reporting frames Apple's pitch as a privacy-forward counterpoint to competitors, but independent coverage highlights that privacy assurances and action-capability create different risk profiles that product teams must manage Fortune; Cringely . What to watch Editorial analysis: Observers should track three indicators: adoption and coverage of the Gemini integration in independent tests; how Apple constrains or logs agent actions across apps platform-level APIs, permission prompts, undo/consent UX ; and the frequency and severity of action-driven errors reported by early users and reviewers. Also watch enterprise guidance and documentation from Apple about developer controls for Siri AI in third-party apps. Quoted context Fortune reproduces Apple software chief Craig Federighi's WWDC remark criticizing a race-for-AI approach: "Some appear to be racing forward, seemingly pursuing AI for the sake of AI, without clear regard for the people, all of us, that it's ultimately meant to serve" Fortune . That quote frames Apple's public positioning but does not specify technical guardrails for action-taking assistants. For practitioners: integrating an assistant with hands emphasizes robust end-to-end testing, more conservative defaults for action permissions, and clearer audit trails. Industry teams deploying assistant-driven automation should expect to instrument action confirmations, rollback paths, and monitoring that treats generated actions as first-class events for reliability and safety analysis. Scoring Rationale A major consumer-platform vendor shipped an assistant that couples rich on-device context with cross-app actions, which materially raises operational and design requirements for practitioners.
