Summary
Craig Federighi said Apple’s new Siri in iOS 27 uses 3rd-generation Apple Foundation Models built with Google, not Google Assistant, Gemini app code, Google Search or Google’s customer-facing model infrastructure.
Apple said the system routes requests through on-device models first, then to Private Cloud Compute when needed, with Apple’s System Orchestrator managing app actions, personal context and privacy controls.
Amar Subramanya outlined 5 key models: AFM Core, Core Advanced, Cloud, Cloud Image and Cloud Pro, saying all improve materially on the prior generation and span on-device, server and image tasks.
AFM Cloud Pro handles the hardest jobs such as agentic tool use and complex reasoning; Apple said it worked with Google and Nvidia to run that model on Nvidia GPUs in Google’s cloud while preserving Apple privacy guarantees.
Apple said the model family underpins the Siri AI and broader Apple Intelligence features shown at WWDC, while current-events answers are grounded through Apple’s own World Knowledge Service.
