What is a token?
Tokens are the text units processed and billed by language models. A token can be part of a word, a whole short word, punctuation, or a code symbol.
V1 uses a transparent character-based estimate. Actual counts vary by tokenizer, language, formatting, and code density, so the result is always labeled estimated.
