AI model API pricing

List prices for 42 current AI models, in US dollars per million tokens, each with the date it was last checked against the vendor's own pricing page. Most recent verification: October 17, 2026. The last column is the cost of one reference task — 30,000 input tokens and 5,000 output tokens — so models can be compared on one number.

How to read this table

• List price, standard tier. Prices are the vendor's published per-token rates for the standard API. Batch, cached-input, fast-mode, long-context and regional rates differ and are not shown; where a row is an introductory, promotional or off-peak rate, it says so.
• Each row has its own verification date. That is the day the price was checked against the vendor's pricing page. Vendors change prices without notice — confirm on the vendor's page (linked in the Vendor column where available) before committing a budget.
• Token price is not task cost. Models differ several-fold in how many tokens they consume to finish the same task, so a cheaper token can produce a more expensive job. The reference-task column removes the input/output mix from the comparison, not the efficiency difference.
• Only individually verified rows are listed. 1 older models whose prices have not been re-checked recently are left out until they are.

How this page is maintained

The table is generated from the dated price reference that every andrew.ooo page draws from. That reference is updated whenever our research finds a vendor price change. Every row is also compared with the vendor's own pricing page once a day, and its date moves forward only on a day that page showed the model at that price; a row the vendor page no longer lists keeps its last confirmed date. We never use our own earlier pages as the source for a price — see the editorial policy and the corrections log for why.
