Catalogue / OpenAI / gpt-5-mini

gpt-5-mini

Prices and limits, each value carrying the date it was observed and the source it came from.

What does gpt-5-mini cost?

Does the price change with the hour or the size of the request?

Yes. This provider publishes conditional rates, so the figure above is not the only price you can pay. Each rate below applies under a stated condition, taken verbatim from the provider's own catalogue.

We record each conditional rate as its own dated observation, so a discount window that disappears shows up as a change like any other.

How has gpt-5-mini moved?

Has gpt-5-mini changed price?

No change has been recorded since we started observing this service on 25 August 2026. We record a change only when two successive observations differ, so an empty table here means the values have held.

What does gpt-5-mini cost elsewhere?

We track this model at 2 sellers. The same model rarely costs the same everywhere, and the difference is not visible from any single seller's catalogue.

Where these figures come from

Source: OpenAI. Every figure on this page was read from OpenAI's own published price list, and every row above links straight back to it. We publish factual values with attribution, we do not reproduce OpenAI'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 OpenAI's own published price list, which we rank as a level 3 source. We re-check it every day. 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.
