Output tokens

Also called: output token, completion tokens, generated tokens, tokens out, output cost

The tokens the model writes back. They cost more per token than input because producing text takes more computing work, and a model's reasoning steps usually count as output too.

For example: Asking for a one-line answer instead of a three-page report cuts the output tokens, and the cost, of every call.
