How this ranking works
All tiered prices: 32,301 prices from 636 sites (about 556 companies). 30,366 are ranked, from 631 sites (about 551 companies); 1,935 more are listed separately and not ranked. Prices collected up to 2026-10-24.
This model has 862 tiered prices; 795 can be compared directly (766 ranked, 29 listed separately). Not comparable yet: display unit not confirmed 40, new price under review; showing the previous one 23, formula-based rule pricing 4
4 recent · 0 stale (older than 10 days, or not updated by this refresh) · 0 unverified timestamps. Minimum and median only count recent paid prices; older prices stay in the table. 0 zero values are separately unverified, without proof of free eligibility.
For tiered models (e.g. longer context costs more) we use the standard tier: shortest context, normal service tier, base price without promotions. Prices that change with time of day or request options are listed separately with the reason. See “Details” for the full rules.
Prices are converted to site credits using each site’s published ratio and display multiplier. What you actually pay depends on its top-up rate. 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 “same company” by identical prices, status pages or homepage code; this is not a legal finding. To see every site’s prices, choose “All plans” or filter by provider.
