OpenRouter no longer lists this offer on its price page. The figures below are the last we observed, and they carry the day we observed them. We keep them rather than deleting the page: a price that was true on a date stays a fact, and a URL that vanishes is a citation that rots.

Do not read these as what you would pay today. Check what OpenRouter still sells, or the same model at other sellers.

Where these figures come from

Source: OpenRouter. Every figure on this page was read from OpenRouter's own published price list, and every row above links straight back to it. We publish factual values with attribution, we do not reproduce OpenRouter's content, and we send readers to them. If you publish this source and want us to stop tracking it, write to contact@bertrande.com and we will act on it without argument.

How is this page verified?

Every figure above comes from OpenRouter's own published price list, which we rank as a level 1 source. We re-check it every 6 hours. Each observation stores the exact source URL and a SHA-256 fingerprint of the source content at that moment, which is what lets us prove what the source said on a given day.

The Proof column shows the first twelve characters of the SHA-256 fingerprint of the source content at the moment we read it. Hover it for the full value. It is what lets us demonstrate later what the source said on a given day, after that page has changed or vanished. The full fingerprints are in data.json.

No value on this page was produced, estimated or completed by a language model. Where we do not have a verified figure, the row is absent rather than filled in. Read the full methodology, or report an error.

Want to know when this changes? Point a feed reader or a script at the Atom feed, which carries every confirmed change and is rebuilt hourly, or poll this page's data.json, where every figure carries its observation date and the fingerprint of its source. Both work today and need no address.
