Knowledge cutoff
The date after which an AI model has no built-in knowledge.
In plain English
Anything that happened after the cutoff is invisible to the model unless it searches the web. That is why fresh, crawlable pages matter: they are how new facts reach AI answers.
In practice
A clinic changed its hours last month. A model answering from memory still gives the old hours.
