Token basics

What are AI tokens?

Tokens are the small pieces of text an AI model reads and writes. A token can be a whole short word, part of a longer word, punctuation, or a number. Models use tokens to measure request size, response length, context limits, and often cost.

Input tokens

Your prompt, attachments, instructions, and relevant chat history.

Output tokens

The response generated by the model.

Context window

The total amount of input and output a model can consider at once.

As a rough English-language guide, 100 tokens is often around 70-80 words. Exact counts vary by model, language, formatting, and tokenizer.

Token estimator

Type or paste text to estimate its input token count.

11

Est. tokens

9

50

Characters

This is a local estimate. The final API response may report a different count because each model provider tokenizes text differently.

Chat & reasoning models

Grouped by provider. Models marked with a wrench can call tools (image generation, functions).
