How we count
A free tier is a limit rather than a price, so none of these rows counts as cheapest anywhere on the site. They are worth knowing anyway, and they are ranked by what the maker charges for the same model, because that is what the free calls save you. 77 models have one, the dearest being o3-pro at $35 per million tokens. The price beside each row is the cheapest we can account for once you outgrow the free tier. Prices are per million tokens, blended 3 in : 1 out, at each provider's standard rate.
A price below the maker's is listed only when the provider says why.
