DeepSeek V3.1 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. DeepSeek trained DeepSeek V3.1 and sells it on no catalog we read, so the price every row is measured against is OpenRouter's.

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.

Credits

Priced in credits or points that convert to dollars, so the rate moves when the conversion does.

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.

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.
