Private Cloud Compute

Apple announced five third-generation foundation models at WWDC26, headlined by AFM 3 Core Advanced—a 20-billion-parameter sparse model that runs on-device by activating only 1-4 billion parameters at a time. For the first time, Apple extended Private Cloud Compute to third-party infrastructure, with AFM 3 Cloud Pro running on Nvidia GPUs in Google Cloud.

Apple executives revealed at WWDC that its most advanced AI model, AFM Cloud Pro, runs on Nvidia GPUs deployed in Google's cloud infrastructure while maintaining Apple's privacy guarantees. The company disclosed it uses Google's Gemini frontier models to refine its own custom models built for Apple Silicon.

Apple's senior vice president Craig Federighi disclosed that iOS 27's Siri AI uses a family of third-generation Apple Foundation Models trained with outputs from Google's Gemini frontier models. The most capable model, AFM Cloud Pro, runs on Nvidia GPUs in Google's cloud infrastructure while maintaining Apple's Private Cloud Compute privacy architecture.
