A set of signed, checkable statements about an AI model or agent: its origin, lineage, build, runtime, configuration, principal and validity.
An AI passport answers three questions for anyone about to rely on an AI: what is it, where did it come from, and who does it work for. Each answer is a signed claim, some declared by the maker (training data, lineage), some measured by hardware (the runtime).
The word also has a precise meaning in attestation. In the IETF RATS passport model, a system obtains a verifier's signed result and carries it to whoever needs to see it. An AI passport works the same way.
Like a travel passport, it expires. A retrained model, a changed system prompt or a new operator needs a new one. See the AI passport service.
