Gemma 4 31B IT pricing.

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.

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 OpenRouter's own is listed as cheapest only when the provider says why. Google trained Gemma 4 31B IT and sells it on no catalog we read, so the price every row is measured against is OpenRouter's.

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.

Lower precision

The open weights, served at a lower precision than the maker's, so not quite the same product.

Promotion

A discount the provider publishes, which may end.

Same as maker

Sold by someone else at the price the maker charges.

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.
