Definition
Private Cloud Compute (PCC) is Apple’s server-side inference infrastructure for Foundation Models, designed to handle queries exceeding on-device capability while maintaining privacy guarantees. At WWDC 2026, Apple extended PCC with a next-generation model built in collaboration with google Gemini, accessible through the language-model-protocol.

Small Business Program Benefit
Developers enrolled in the App Store Small Business Program with fewer than 2 million total first-time App Store downloads can access next-generation Apple Foundation Models on Private Cloud Compute at no cloud API cost — a significant subsidy for indie developers compared to per-token billing from third-party providers.
Architecture Position
PCC sits between on-device Neural Engine inference and third-party cloud models (Claude, Gemini) in Apple’s three-tier model routing:
- On-device (Neural Engine) — free, private, limited capability
- Private Cloud Compute — Apple-managed, privacy-preserving, free for Small Business
- Third-party cloud (Claude, Gemini) — per-token costs, developer opt-in
