attention — The mechanism that lets a model weigh which earlier words matter for the word it's currently processing — the core operation of a transformer.
embedding — A list of numbers representing a piece of text's meaning, so that similar meanings end up numerically close and can be searched.
context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.
