How to Detect When an AI Model Is Using an Outdated Retrieval Index

A model may cite stale information when its retrieval index did not refresh after source documents changed. Model availability checks will not reveal the content gap.

What to check

Compare source version dates with index timestamps, ingestion status, deleted document handling, and retrieved passages for known queries.

Recommended next step

Alert on indexing lag and test freshness using approved sample questions. Informatix Systems can assess AI knowledge pipelines and production monitoring.
