In NIST's definition, an AI system is machine-based and, given a set of objectives, produces outputs like predictions, recommendations or decisions.
On its own, that output still needs something to act on it.
A model can draft a reply or score a lead, but it does not file, route or update records unless another system carries the result forward.
