How this ranking works

All tiered prices: 30,485 prices from 636 sites (about 555 companies). 28,608 are ranked, from 629 sites (about 548 companies); 1,877 more are listed separately and not ranked. Prices collected up to 2026-10-17.

This model has 31 tiered prices; 30 can be compared directly (29 ranked, 1 listed separately). Not comparable yet: display unit not confirmed 1

0 recent · 0 stale (older than 10 days, or not updated by this refresh) · 0 unverified timestamps. No recent prices to summarize in this group. 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.
