Official comparison methodology & sources

For the selected input length, each rate uses the higher of domestic and overseas official standard pay-as-you-go prices. Domestic rates are converted to USD. Savings use the lower input/output discount; storage, tool fees and batch discounts are excluded. Image, video and audio models are compared at the same model version and unit; our video price is the same at every resolution, so the comparison uses the official price at the lowest resolution the model supports. Only models with a published official price are shown.
