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 4 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 4 hosts: Nebius at $0.25 input / $1.00 output per 1M tokens. It serves a quantized fp8 build, which is not the same product as the full-precision model. The dearest, Together, charges 1.2x the cheapest.
| Host | Input $/1M | Output $/1M | Precision |
|---|---|---|---|
| Nebius (price we quote) | $0.25 | $1.00 | fp8 |
| CoreWeave | $0.30 | $1.00 | fp4 |
| BaseTen | $0.40 | $1.20 | fp4 |
| Together | $0.40 | $1.20 | not declared |
List prices as published on 2026-10-22, via OpenRouter. Negotiated rates, committed-use discounts and provisioned capacity are not shown. These hosts do not all serve the model at the same numeric precision, so the cheapest is not a like-for-like substitute for the dearest.
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 reflection publishes those rates), which assumes you implement both, to the list price. One figure means no discount is published.
