| Note | Meta's description of its own system; supports only "Meta reports" statements. Private Processing runs WhatsApp's AI requests in confidential VMs on AMD EPYC CPUs with SEV-SNP and NVIDIA Hopper GPUs. The client checks the attestation and transparency proofs, including entries in a third-party transparency log run with Cloudflare, before it connects. The threat model lists physical host attacks, with data-centre security, memory encryption and third-party relays as mitigations. |
