# Billing notesBatch, Flex, Priority, and regional processing tiers are not listed. Search, cache storage, and modality-specific audio, image, or video token rates can add separate usage. The completed upstream usage and the billing snapshot attached to the request determine the final debit. Use the dashboard Models page for the current project-visible catalog.
