Pricing for additional GPT-4 Uses

General
1

Is there any info on how much additional GPT-4 uses costs? I couldn’t find it anywhere on the website or via a basic forum search.

EDIT:
On the checkout page I have found the relevant information. Does this apply for each month, like would it be for each year it’s 1000 requests per month?
Would definitely be great to have this somewhere on the website.

In addition to the initial cost of $20 for a subscription, each additional 500 requests will also cost $20 per month. This means that if you purchase a subscription and need an additional 500 requests, the total monthly cost will be $40.
