AI model API prices over time

Open data

This chart reads the open AI Price Index dataset (CC BY 4.0). The machine-readable JSON, the methodology, and a cite line are at the open-data endpoint.

AI Price Index by RoninForge (https://roninforge.org/data/ai-price-index/), CC BY 4.0. Prices validated as of 2026-06-17.

Frequently asked questions

Where does the data come from?

Every price is transcribed from the provider official pricing page, with the source link and the date it was last validated. The full dataset is open under CC BY 4.0.

Is the price history complete?

It is growing flagship first. Each price carries a confidence label, and reconstructed history is never shown with the same weight as a live-confirmed price.

Does anything I do here leave my browser?

No. The chart reads a static dataset shipped with the page and renders entirely in your browser. There is no upload and nothing you do is tracked.

Can I use the data in my own work?

Yes, under CC BY 4.0 with attribution. The machine-readable JSON and a cite line are at the open-data endpoint.

Sources
