Where these figures come from

Source: DeepInfra. Every figure on this page was read from DeepInfra's own published price list, and every row above links straight back to it. We publish factual values with attribution, we do not reproduce DeepInfra'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 DeepInfra'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.
