## Definition

A token is a small piece of text, such as a word fragment, word, punctuation mark, or space pattern, that a language model processes.

## Quick Answer

Tokens matter in AI roleplay because character cards, personas, summaries, lore, and recent messages all consume the model's available context before it writes the next reply.

## Plain Language

A long card, long recap, or long chat history is not free. It takes up room in the model's working text budget.

## Why It Matters

Token awareness helps creators write shorter cards, cleaner summaries, and lore entries that do not crowd out the live scene.

## OnlyKin Angle

OnlyKin can turn token complexity into simple product guidance: write compact cards and preserve only memory that changes the next scene.
