The board shows this model's cheapest measured offer ($11.25/1M); the smaller figure under it is the mean of the 5 offers listed below ($11.25/1M). Add those up and divide — it matches. 1 offer(s) above 10x the median were left out of the average and flagged ⚠ in the table below — they are still listed, and still compete for the cheapest price. 24h token volume (23B) 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.
