How this is built
Prices are read from OpenRouter's public model list, which routes to each vendor and publishes the per-token price it charges — for nearly every model, the vendor's own list price passed through. It is the one place all vendors appear in one schema, which is why it is the source. Prices are shown as listed there; a vendor's direct price can differ, especially with volume discounts or provisioned throughput, and OpenRouter's own listing is the reference for what is shown.
Every collector run is stored as a snapshot and committed to the repository, so price changes are diffs anyone can inspect. Nothing is backfilled. The 7-day column compares a model against itself a week earlier and is blank until that run exists.
Blended weights input at 3 and output at 1. Change the ratio and the ranking changes — an output-heavy workload makes the frontier tier relatively more expensive, since output tokens cost five times input on most frontier models.
