Context window

A context window is the maximum amount of text AI search can hold in mind at once, counted in tokens.

In a little more detail

Anything beyond it is simply not there. When AI search seems to forget the start of a long conversation or a long document, this is usually why.

Related terms

Token: A token is a chunk of text, usually a word or part of a word, and it is the unit AI search actually reads and counts.
LLM: An LLM, or large language model, is the program underneath AI search: software trained on an enormous amount of text that predicts what words should come next.
