How billing works

The details that turn a token rate into an actual bill.

Use the published billing unit

This model uses / 1M tokens, / 1M tokens. Do not substitute a text-token estimate for image, audio, video, or document charges.

A missing rate is not free usage

If a price, discount, or limit is marked not published, confirm it with the provider before estimating spend. The calculator does not invent a separate cache discount when no cached-input rate is available.

Check discounts and rate tiers

Eligible batch requests use 50% of the standard token rate in this listing. Batch work is asynchronous; check supported endpoints and turnaround times. Review the provider's pricing terms for workload-specific conditions.

Account for the complete workflow

Retries, follow-up calls, and agent tool loops increase request counts. Search, storage, and other tool charges can be billed separately from model inference. Use actual API usage logs to calibrate a budget before scaling traffic.
