Apple unveils Siri 2.0, Extensions API, and Gemini deal

Executive Signal Summary

At WWDC 2026 (June 8), Apple announced Siri 2.0 built on a custom 1.2‑trillion‑parameter Google Gemini model and an Extensions API that lets users route Apple Intelligence features (Siri, Writing Tools, Image Playground) to third‑party models such as Anthropic Claude, OpenAI ChatGPT, or Google Gemini. Apple licensed the custom Gemini model at a reported $1 billion per year; that model runs on Apple’s Private Cloud Compute (PCC) with cryptographic attestation. iOS 27 introduces a standalone Siri app and App Intents 2.0 (streaming responses, richer entity types, conversational follow‑ups). Developer beta 1 dropped June 8, 2026; public iOS 27 is expected September 2026 (iPhone 12+ supported). Extensions route queries either to Apple PCC or to the chosen third‑party provider under that provider’s privacy policy; iOS 27 GA lacks MDM controls for blocking Extensions.

Apple powers Siri with Gemini, accelerates launch

Speculation becomes reality as Apple accelerates a major Siri update powered by Google's Gemini. The rollout is planned to be showcased at an upcoming event and subsequently tested in the iOS 26.4 beta, marking the biggest Siri update in years. Gemini will serve as the base model for Siri and Apple's Foundation Models, enabling deeper integration of external AI into the OS while balancing on-device and private cloud compute to protect user data. The collaboration signals a significant shift in the AI race, with Google strengthening its role across iPhone touchpoints and monetization potential. Prior discussions with Anthropic and OpenAI are noted, with Anthropic reportedly priced out and OpenAI collaboration described as challenging. Bloomberg is cited as having reported the schedule. The arrangement could heighten competitive pressure among AI players and influence the economics of AI-enabled features on Apple devices.

Apple's Siri to Use Google's Gemini

Rumors converge around Apple’s plan to overhaul Siri by powering a new version with Google’s Gemini AI. The refreshed Siri is expected to ship with iOS 26.4, with a launch possibly in spring 2026. Apple reportedly evaluated competing AI systems from OpenAI (ChatGPT) and Anthropic (Claude), but Bloomberg and Apple-connected sources indicate Google won the race, and a Gemini model tailored for Siri is already in testing on Apple’s servers. The negotiations reportedly include terms for deeper Gemini integration and reflect long-standing Google-Apple arrangements, including Google’s past payments to be the default iPhone search engine. Beyond Siri, Apple pursues broader AI ambitions, including an AI search strategy and a shift to Apple Ads, with ads in Apple Maps anticipated in 2026 and a gradual rollout of Apple Intelligence in Germany since 2025. Deployment pace within Apple’s ecosystem remains cautious.

Apple Licenses Google's Gemini for Siri

On the eve of Apple’s 50th anniversary, CNBC reports Apple is at a crossroads as it accelerates AI efforts after years of relative caution. In January Apple struck a multiyear deal to license Google’s Gemini models as part of a rebooted Siri, reversing its historical preference for keeping intelligence and data processing primarily on-device. Former employees and industry analysts say Apple lagged in generative AI, noting a missed multi-year lead with Siri and slower capital investment in cloud AI infrastructure compared with rivals. The Google deal raises questions about data sharing and whether Apple can preserve its privacy commitments while relying on third-party models. Observers say Apple can still compete if it successfully blends on-device inference, secure cloud extensions, and user-focused experiences.
