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.
