Knowledge cutoff
A knowledge cutoff is the date after which a model learned nothing during training.
In a little more detail
Ask about something newer and AI search either says it does not know, or fetches live pages, or guesses. It is the clearest illustration of why retrieval, not training, is where a business can compete.

- Training data: Training data is the enormous body of text AI search learned from before it was released, which is fixed, often months or years old, and cannot be edited by you.
- Retrieval: Retrieval is the step where AI search fetches live web pages in the middle of answering you, instead of relying only on what it already knows.
