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 3 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 3 hosts: OpenAI at $10.00 input / $50.00 output per 1M tokens. All of them charge within 10% of one another.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| OpenAI (model maker, price we quote) | $10.00 | $50.00 |
| Azure (price we quote) | $10.00 | $50.00 |
| Amazon Bedrock | $11.00 | $55.00 |

Monthly cost at 100K requests, by business use case
