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 $0.03 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.
