The ORNNTOKO settled at $0.47 per million tokens for OpenAI as of October 11, 2026: the price of the average paid OpenAI token served that day.

How much do OpenAI tokens cost per million?
OpenAI inference settles at $0.47 per million tokens on the Ornn Token Price Index (ORNNTOKO), as of October 11, 2026. That is a volume-weighted blend across OpenAI's paid production models, so higher-volume models move it more than thinly used ones; any single model's list price can sit above or below it.
Are OpenAI tokens getting cheaper?
The ORNNTOKO has moved +17.0% over the last seven days and +9.2% over thirty days (from $0.43 per million tokens). The three-month public window spans $0.16 (low) to $1.60 (high). Daily settled values and 1/7/30-day changes are published on this page.
How is the ORNNTOKO calculated?
Each settlement day, the ORNNTOKO is a volume-weighted blend of posted per-token prices across OpenAI's paid production models: effectively the price of the average paid OpenAI token served that day. Free tiers and open-weight self-hosting are excluded, and models without enough pricing coverage on the day are excluded too, so a light-coverage day is dropped rather than published with a partial blend. Each day settles shortly after it ends and is stable once settled.
Is the OpenAI token price index on Bloomberg?
