A New Standard for Cloud AI Privacy
When user requests exceed local on-device parameter budgets, Apple routes queries to Private Cloud Compute (PCC) clusters powered by custom Apple Silicon servers. Independent security researchers and cryptographic auditors have verified that PCC enforces strict non-targetability, ephemeral storage, and verifiable software transparency.
Hardware Root of Trust
Each PCC node boots with a secure enclave and sealed hardware keys. If Apple pushes a code change, external security researchers can inspect the cryptographic hash before any user traffic is routed, establishing the most secure cloud AI architecture in production today.
