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: Google at $0.25 input / $1.50 output per 1M tokens. All of them charge within 10% of one another.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| Google (model maker, price we quote) | $0.25 | $1.50 |
| Google AI Studio (price we quote) | $0.25 | $1.50 |
