What you pay

01 · What counts

Input and output tokens

Reported in the usage block of every response. Billing is quantised, so a very small request may round to zero.

02 · Failures

A failed request is not billed

A request you disconnect from is billed. A timeout that fires early does not cancel the work.

03 · Cache

Reads at 0.10×, writes at 1.25×

Of the model's own input fare. Cache read is its own column on the fare card.

04 · Currency

USD, no conversion

Text, image and video share one USD balance whatever the interface language.

Get a key, change the base URL, send a request.
