Questions & answers

What is a token?

A token is a small piece of text, about 4 letters. AI companies charge by how many tokens you send in and get back.

Why do answers cost more than questions?

Writing an answer takes the AI more work, so output tokens usually cost several times more than input tokens.

Is this calculator free?

Yes. It runs in your browser and nothing you type is saved or sent anywhere.

Are these prices exact?

They are estimates. Providers change prices often, so use the “Check price” links before you buy.
