How billing works
The details that turn a token rate into an actual bill.
Use the published billing unit
This model uses / 1M characters. 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
No batch multiplier is applied to the examples on this page. Check the pricing source before assuming an asynchronous job receives a discount. 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.
