AI now makes decisions across enterprise and public services every day, and regulation (EU AI Act, ISO 42001) is mandating explainability. But model logs are vendor-controlled and rotate with each upgrade, so there is still no mechanism to verify, after the fact, why a model decided what it decided. Lemma records the inputs, retrieved sources, applied rules, and model generation behind each decision as a tamper-evident attestation, so the audit trail outlives the model version it was made on.
EU AI Act enforcement in 2026; rising ISO 42001 certification demand
- ZK attribution — prove which model generation made a decision, on which data, verifiable years later
- RAG provenance anchoring — retrieved citations can't drift or be silently reissued
- Selective disclosure for compliance reports — reveal only what the auditor needs, not the full input
