API pricing Subscriptions
How to read this page
API pricing is pay-as-you-go: you only pay for what you use. Prices are per 1M tokens (roughly 750,000 words, depending on language and formatting). Input is the text you send to the model; output is the text it generates for you. Some providers also offer cached input, which can reduce costs when you reuse the same text. Want a walkthrough? Follow our tutorial.
