Apple Unveils Gemini-Powered Siri and iOS 27 at WWDC 2026

Apple confirmed at its WWDC 2026 keynote on June 8 that it is delivering "the next generation of Apple Intelligence" and introducing Siri AI, "an entirely new version of Siri," built on a new architecture Apple says is designed to protect user privacy (Apple newsroom). TechCrunch's post-keynote coverage confirms the assistant runs "with Google Gemini under the hood," and that Apple said it collaborated with Google and the Gemini family of models to build the next generation of Apple Foundation Models (TechCrunch). This validates pre-keynote reporting from Bloomberg's Mark Gurman, who had reported Apple would pay Google roughly $1 billion per year for a custom, approximately 1.2-trillion-parameter Gemini model to run Siri's cloud-based reasoning, while Apple continues to handle privacy-sensitive tasks on-device (Bloomberg).

Siri AI ships as a standalone app deeply integrated across iPhone, iPad, Mac, Apple Watch, and Apple Vision Pro. Apple says it can draw on personal-context understanding to search across messages, emails, and photos; act on-screen content; reach out to the web for up-to-date answers; and sync conversation history privately across devices via iCloud (Apple). This matches earlier reporting from 9to5Mac, MacRumors, and AppleInsider describing a system-wide "Search or Ask" interface, on-screen awareness, and cross-app actions.

New Siri AI and Apple Intelligence features are available for developer testing now across iOS 27, iPadOS 27, macOS 27, and visionOS 27, with a public beta following in July and general release this fall (Apple). Siri AI will be available as a beta in English first, with Apple "quickly" expanding language support; on iPhone and iPad, Siri AI will not launch initially in the EU due to Digital Markets Act constraints, and it will not launch in China while Apple works through regulatory requirements (Apple).

Pairing an external frontier LLM with on-device models is now a common hybrid pattern for balancing capability, latency, and privacy; Apple's version routes simple tasks on-device, moderate requests to Apple's Private Cloud Compute, and the heaviest reasoning to Google Cloud infrastructure. A platform-level default-plus-alternative model toggle (Siri alongside options like ChatGPT or Gemini, per earlier 9to5Mac reporting) echoes prior search-engine-style distribution arrangements, treating the underlying model as a swappable backend rather than a proprietary moat.

Developer entitlements and API scope for personal-context access; how the on-device/Private-Cloud-Compute/Google-Cloud routing performs on latency and cost at scale; and whether the EU delay (tied to DMA compliance) or China unavailability becomes a lasting carve-out rather than a launch-timing issue. Beta feedback through the northern-hemisphere summer will be the first real signal of whether Siri AI closes the gap with ChatGPT's and Gemini's own assistant products.
