How this ranking works
All per-token prices: 97,455 prices from 871 sites (about 765 companies). 89,631 are ranked, from 861 sites (about 755 companies); 7,824 more are listed separately and not ranked. Prices collected up to 2026-10-17.
This model has 274 recorded prices; 140 can be compared directly (139 ranked, 1 listed separately). Not comparable yet: price not parsed yet 76, scope of the official doc price not confirmed 24, billed per request or another unit 17, ratio looks unset 8, new price under review; showing the previous one 1, tiered by rules (see Tiered prices) 1
2 recent ยท 0 stale (older than 10 days, or not updated by this refresh) ยท 0 unverified timestamps. Minimum and median only count recent paid prices; older prices stay in the table. 0 zero-valued pairs are separately unverified, without proof of free eligibility. Timing does not verify payment, upstream identity or quality.
Prices are converted to site credits using each siteโs published ratio. What you actually pay depends on its top-up rate. Input, output and cache prices in each row come from the same plan. Several sites run by the same company take one place in the ranking: its cheapest plan, with the other sites listed under it. We judge โsame companyโ by identical prices, status pages or homepage code; this is not a legal finding. To see every siteโs prices, choose โAll plansโ or filter by provider.
โSelf-declared unofficial channelโ means the plan name itself says โreverse-engineeredโ or similar. We have not verified their source or quality. Minimum and median only count regular plans.
