Knowledge cutoff
The date after which an AI simply has not read anything.
An AI only knows about the world up to the point when its training data was collected, and that point is called the knowledge cutoff. Anything that happened after that date is a blank to the model unless it is given fresh information or allowed to search the web. This is why an AI can be confidently out of date about recent news.
For example
If a model's cutoff is early 2025, it will not know who won an election held later that year.
