What you pay more

A page is about 600 tokens in and 60 out, a support reply 200 in and 300 out, an email 150 in and 250 out. Nothing else is counted: no cache discount, no batch rate, no free tier.

How we count

Prices are per million tokens. The big number on each row is blended 3 in : 1 out, the way most work uses a model. A price below OpenAI's own is listed as cheapest only when the provider says why.

Costs more
Sold by someone else for more than the maker charges.
Maker's price
What the lab that trained the model charges on its own API. Every other row is measured against it.
