(3 × $0.100 + $0.600) ÷ 4 = $0.225/1M — the $/1M figure blends input and output at 3:1 — that is the only way models with two different rates can be ranked on one axis. Your actual rate depends on your own input:output mix — input only $0.100, 3:1 $0.225, 1:1 $0.350, output only $0.600 per 1M.

The board shows this model's cheapest measured offer ($0.225/1M); the smaller figure under it is the mean of the 1 offers listed below ($0.225/1M). Add those up and divide — it matches. 24h token volume (73B) is sourced from OpenRouter public rankings — today's only public source of absolute per-model token counts (Vercel AI Gateway publishes share-of-traffic percentages); as more sources come online, the per-router breakdown will sum to this total here.
