How billing works
The details that turn a token rate into an actual bill.
Use the published billing unit
This model uses / 1M tokens. Do not substitute a text-token estimate for image, audio, video, or document charges.
Cache hits have their own rate
The listed cached-input price is $0.20 per million tokens. Reusing a prompt does not automatically qualify: use the provider's reported cached-token count, and account for any cache-write or storage charges.
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.
