Top scorer is measured quality alone, out of 100. The picks weigh quality against live price and speed.

Quality is Nivana’s measured score for each kind of task, from weekly pairwise evals judged by models from several labs. Prices are live AI Gateway list prices per million tokens. Updated 2026-11-01. How this is measured.
