What you save

A page is about 600 tokens in and 60 out, a support reply 200 in and 300 out, an email 150 in and 250 out. Nothing else is counted: no cache discount, no batch rate, no free tier.

How we count

Prices are per million tokens. The big number on each row is blended 3 in : 1 out, the way most work uses a model. A price below Z.ai's own is listed as cheapest only when the provider says why.

Resells
The provider sells another company's endpoint, at a margin of its own or at the maker's price.
Runs it themselves
The provider runs the open weights on hardware of its own, so the price is its own rather than a resale.
Credits
Priced in credits or points that convert to dollars, so the rate moves when the conversion does.
Regional price
A price list for one region, lower than the international one. A region, not a deal.
Lower precision
The open weights, served at a lower precision than the maker's, so not quite the same product.
Same as maker
Sold by someone else at the price the maker charges.
Maker's price
What the lab that trained the model charges on its own API. Every other row is measured against it.
