KC-D15
· Company claim
· Signal
A hallucination is output from a language model that reads as confident and well-formed but is not supported, either by the material the model was given or, where none was given, by verifiable real-world fact.
What this record is
This is one entry in The Knowledge Company claim register: a statement the company publishes, the source it was checked against, the date of the last check and the date that check expires. When the stale-after date passes, the status degrades on its own until a person re-verifies the claim. Nothing is marked verified automatically.
