A high-school playbill desk pastes a long safety script into a writing assistant and is billed by pieces of text, not by number of documents. The bill is not counting meaning-vectors and is not the size of the model's working memory. What unit is the desk being billed for?
Select an answer to reveal the explanation.
Short Explanation
Think of paying by the slice of bread, not by the loaf. Tokens are the chunks the model reads or writes, and that is the bill. Embeddings are meaning-vectors, the context window is how much fits on the plate, and this is not clustering.
Full Explanation
A token is a chunk of text the model consumes or produces, which is the unit on that bill. An embedding is a numeric meaning vector, not the billed piece of text. The context window is how many tokens can fit at once, not the billing unit itself. Writing assistance is not clustering.
