An LLM token is a chunk of text a language model works with: a whole word, part of a word, a punctuation mark or a space. Models read and write text in tokens, so tokens are how you measure:
- The size of the context window
- The length of a prompt and a response
- What a model provider charges per request
- Usage limits
Russian text usually breaks into more tokens than English text with the same meaning.
Don't confuse it with a Pachca API token, the secret key an agent or integration uses to authorize API requests. Pachca's tools help agents save LLM tokens: Pachca CLI returns command details only when asked, and the docs are available in Markdown without extra markup.
