What it costs for your work
A month at Z.ai's own price
A month at HPC-AI, the cheapest
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.
- Runs it themselves
- The provider runs the open weights on hardware of its own, so the price is its own rather than a resale.
- Resells
- The provider sells another company's endpoint, at a margin of its own or at the maker's price.
- Lower precision
- The open weights, served at a lower precision than the maker's, so not quite the same product.
- 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.
- 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.
- Costs more
- Sold by someone else for more than the maker charges.
- Free tier
- Given away inside a quota. A limit is not a price, so it is never called cheapest.
- Not ranked
- Below the maker's price on a closed model with nothing to account for it, or from a catalog we could not read reliably. Listed, and never a pick.
