Ranked by AA Intelligence Index — independent leaderboard data; benchmark citations are on each model page. Scores flagged “vendor” are the maker's own claim, shown for reference and ranked below independently-scored models; models with no published score rank last, cheapest first. * Blended = (3×input + 1×output) ÷ 4. Every price links to its source on the model page.

How models are selected

Generally-available flagship and reasoning-class models, ranked by the Artificial Analysis Intelligence Index (an independent cross-benchmark composite). One row per model — host duplicates are collapsed. Models without an index score rank below scored ones, cheapest first.

Prices are per million tokens (Mtok), sourced directly from — and linked to — official provider pricing pages. "Blended cost" is (3×input + 1×output) ÷ 4 — weighted toward input because real workloads read far more tokens than they generate.
