Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it.
$2.00$1.10
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.
$12.00$4.40
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.
$0.20$0.55
