PCC · Private Cloud Compute
Apple's verifiable-inference-privacy architecture: attested images, stateless nodes, and a public transparency log — the reference bar for AI privacy claims.
Current numbers
5–20% TDDIEEE 519 current-distortion (TDD) limit at the PCC, sliding with the Isc/IL short-circuit ratio; voltage THD capped at 5% (1–69 kV) / 8% (<1 kV)
5% THD-VIEEE 519-2022 voltage-distortion limit at the PCC for 1-69 kV; 3% per individual harmonic; 8% below 1 kV
