Prompting glossary
Token
The chunks of text AI reads and bills by.
What it means
Models break text into tokens, which are roughly word fragments. Tokens matter to you in two ways: they are how usage is measured, and they are the unit that fills up a context window.
How to use this in practice
Knowing the word is the easy half. The useful half is writing the instruction so the AI does not have to guess: say who it should act as, give it the background it cannot know, state the outcome you want, set the limits, and name the format the answer should come back in. That is the same structure behind every template in the free prompt library.
