What does each model cost?

Prices are per million tokens, in US dollars. Every row names the seller it came from, and where that is not the seller's own published page the mark says so: * means the number comes from a single registry or two that disagree, so it is the best available rather than a confirmed one. The same mark covers both because the remedy is the same — check the seller before you commit.

A row is a rate, not a model. One model can appear four times at four prices — standard, batch, flex, fast — and again for audio or image tokens, and again either side of a context threshold. This page opens on the standard text rates because those are the ones a reader compares; the toggle shows everything.

Where a seller has announced a rise, it is named here. A dated increase a reader can still act on is the most useful thing this table holds, so it sits beside the current rate rather than in a footnote.
