Deprecated. The model maker has announced retirement of this model's API · shutdown 2026-08-05 · suggested replacement: Claude Opus 4.8. It still carries a price because hosts still serve it; treat it as a model to migrate off, not one to start on.
Claude Opus 4.1 has held the same list price since 2026-10-18 and is the 25th cheapest of 31 models in the Premium price tier. Only one host, Amazon Bedrock, sells it, so there is no second price to shop. Its maker has announced its retirement, so it is a model to migrate off rather than start on.

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 1 host. 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.
Amazon Bedrock is the only host with a published rate, $15.00 input / $75.00 output per 1M tokens, which is the price we quote.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| Amazon Bedrock (price we quote) | $15.00 | $75.00 |

Monthly cost at 100K requests, by business use case
