# Knowledge tagged “tokens”

- [Context window](https://joaodavidsilva.com/knowledge/context-window.md): Everything the model sees on each model provider request: finite, model-specific, and the only surface through which it perceives anything.
- [Token](https://joaodavidsilva.com/knowledge/token.md): The atomic unit a model reads and writes; context window size, cost and latency are all counted in tokens.
