Knowledge Cutoff
A knowledge cutoff is the date after which a language model's training data was no longer collected. Events, publications, and facts that emerged after this point are absent from the model's parameters, so it cannot recall them without external tools. Cutoffs are typically months before public release due to training and evaluation timelines.
