Apple says its AI is still private, even when it’s running on Google’s servers
Summary
Apple asserts that its AI remains private even when running on Google's cloud, using a hybrid architecture with on-device models and a Private Cloud Compute (PCC) layer. The system employs confidential computing, Trust Domain Extensions, and a cryptographically verifiable ledger to protect data, with data leaving the device only transiently and only when necessary. The rollout spans iOS 27, iPadOS 27, and macOS 27, with on-device orchestration deciding which data is sent off-device.
