Apple clarified that running some of its AI models on Google's cloud infrastructure does not compromise user privacy. Through its Private Cloud Compute (PCC) architecture, Apple ensures that all data is processed in secure enclaves with end-to-end encryption. Consequently, Google has zero access to user data, addressing privacy concerns over Apple's cloud partnerships.
Simon Willison says Apple’s 2024 Apple Intelligence rollout made him cautious, so he will believe the WWDC 2026 Siri AI claims only after seeing results. He notes the new features look more feasible, especially with a custom Gemini-derived model running on Private Cloud Compute. He also highlights vision LLM screen understanding and the new Core AI library for running PyTorch-derived models on Apple hardware.
Apple announced a major Apple Intelligence overhaul built around Apple Foundation Models co-developed with Google using technologies behind Gemini. The architecture supports on-device and Private Cloud Compute execution, with stronger reasoning, understanding, and multimodal capabilities. A new system orchestrator coordinates AI features across Apple platforms, though Apple has not yet specified which devices receive the higher-power model.
