Price a call from uncached input, cache reads, cache writes and output — then see the same usage on other models.
Calculate your cost02 — How we price
Each price is checked against the vendor’s own page. Results carry the check date and price version, so a saved number never changes silently.
A count is exact only where we verified the model’s tokenizer. Everything else is marked as an estimate — even within the same vendor.
EstimatedIf a price or rule isn’t verified, the cell stays blank and says why. A blank never means free.
UnverifiedUncached input, cache reads, cache writes and output are separate lines — and long and short requests are tiered one by one, never averaged.

We’re building project cost reviews for small teams: bring last period’s usage, see where the money went, set a budget, and check again next period.
