What it is

Language models generate plausible text, not verified facts. When information is missing, they may invent sources, numbers or quotes that look real. It follows from how the models work — it is not a rare bug.

Example

Asked for supporting case law, a model may cite a court ruling that does not exist.

What can go wrong

Wrong numbers or invented sources end up in reports, offers or code.

How to secure it

Ground answers in your documents (RAG) with citations, check results automatically where possible — tests, calculations, totals — and keep a human review for important outputs.
