Where the numbers come from
Quality scores are Elo ratings from the Artificial Analysis image arenas, where people vote between two pictures made from the same prompt without knowing which model made which. The vote split comes from the Elo gap. Prices are for one 1024×1024 image from the Vercel AI Gateway; models billed per token are estimated at the quality the arena scored. The sample pictures are our own runs. Updated November 5, 2026.
