AI Price Index

2 populated days in the window · sample sizes per day in the tooltip · a null median means no offer in that universe on that day.

MethodDaily medians of live USD-per-1M-token prices across every provider offer valid at the end of each UTC day (offers with a zero or missing price are excluded from that median). `median_open_output` covers models with openness open-weights/open-source; `median_embedding_input` covers models whose modalities include embedding. Sample sizes are returned per day; a null median means no offer in that universe on that day. Frontier models = canonical models released in the last 12 months by organizations with at least 3 canonical models, OR holding a top-10 rank in the primary comparability group of at least one benchmark. Artifacts and folded variants are excluded. No composite score is used to pick them. /methodology
