Specifications
ParametersA rough measure of how big the model is. More parameters usually means more capable and more expensive to run, though it is a poor guide on its own — a smaller, newer model often beats a larger, older one.
—2.4T
Context windowHow much text the model can hold in mind at once — your question, any documents you attach, the conversation so far, and its own reply. Go past it and the earliest part falls out of view.

Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it.

Output priceWhat you pay for the text the model writes back. It is normally the dearer half: producing an answer costs more than reading one.
$1.98—
Cached input priceA reduced rate for text you send over and over. If every request starts with the same instructions or the same document, the provider keeps a copy ready and charges less to read it again.
