Every figure is quoted from the vendor's official page, with the date we read it. If a row is missing, the source does not state it and we do not estimate it.

API prices

Cached input cost per 1M tokens
$0.075Rank 5 of 20
What it means and the source

The reduced price when part of the request is identical to one sent recently, for example the same instructions or the same document: the vendor keeps it in memory and charges less for it.

Output cost per 1M tokens
$3.75Rank 6 of 21
What it means and the source
