How to Prove Your AI Did What It Said: A Developer's Guide to Verifiable AI Outputs

Short summary

AI attestation cryptographically proves input/output pairs are authentic and unaltered, creating auditable chain of custody for regulatory defense. It establishes technical proof (what happened) distinct from correctness. Implementation via one post-inference API call enables third-party verification without requiring trust in your logs.

  • Attestation signs AI outputs with a private key and stores them on append-only ledgers, proving they haven't been altered
  • Proves authenticity and integrity of the record, not correctness of the AI's reasoning or decision
  • Implements in one API call per inference with public verification URLs for auditors, regulators, and legal teams

Generated with AI, which can make mistakes.
