What is Knowledge cutoff?
Also called: Training cutoff
The knowledge cutoff is the date up to which a model has seen data. It does not know what happened afterwards unless it searches the web.
Example
A model does not know about a recent price rise and quotes the old price.
For pros
Vendors usually state the cutoff in the model documentation. Current facts need web search, RAG or your own data, with visible sources.
