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 2 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 2 hosts: DeepInfra at $0.075 input / $0.225 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 |
|---|---|---|---|
| DeepInfra (price we quote) | $0.075 | $0.225 | fp4 |
| Novita (price we quote) | $0.075 | $0.225 | not declared |
List prices as published on 2026-10-22, via OpenRouter. Negotiated rates, committed-use discounts and provisioned capacity are not shown. These listings are promotional rates, below the host's standard rate: DeepInfra's, 75% off; and Novita's, 75% off.
Monthly cost at 100K requests, by business use case
From the after-discounts figure (prompt caching on the cached input share, batch API for async workloads, only where inclusionai publishes those rates), which assumes you implement both, to the list price. One figure means no discount is published.
