Official prices are the vendor's cash prices. Inference providers also list cash prices and can be compared directly. Relays list prices in site credit; what you actually pay depends on each site's top-up rate, so they cannot be compared with official prices directly.

Official group, uses AZ plus official channels, can use all models on this site, most stable, very expensive!!! If other groups have it use them first; use this one when other groups stop working well [machine translation]Original: 官方分组,使用AZ加官方渠道,可以使用本站所有模型,最稳定,很贵!!!建议其它分组有的先用其它分组,其它分组不好用了再用这个

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 258 recorded prices; 119 can be compared directly. Not comparable yet: price not parsed yet 89, scope of the official doc price not confirmed 24, display unit not confirmed 7, ratio looks unset 6, billed per request or another unit 4, tiered by rules (see Tiered prices) 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-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 site’s 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 “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.

“Self-declared unofficial channel” means the plan name itself says “reverse-engineered” or similar. We have not verified their source or quality. Minimum and median only count regular plans.
