Pricing by host
A host is a company that runs the model and sells it by the token: the model maker, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent host. One model, several hosts, and often several prices. This model is sold by 6 different hosts. The price we quote elsewhere on this page is marked. We quote one host's rate so that models stay comparable; it is not a recommendation to buy there.
The price we quote is already the cheapest of the 6 hosts: Makora at $1.25 input / $4.25 output per 1M tokens. It serves a quantized fp4 build, which is not the same product as the full-precision model. All of them charge within 10% of one another.
| Host | Input $/1M | Output $/1M | Precision |
|---|---|---|---|
| Makora (price we quote) | $1.25 | $4.25 | fp4 |
| Modal (price we quote) | $1.25 | $4.25 | not declared |
| Together (price we quote) | $1.25 | $4.25 | not declared |
| Nebius (price we quote) | $1.25 | $4.25 | fp4 |
