At these rates
- A workload with 70% input and 30% output costs $6.70 per 1 million total tokens and $670.00 per 100 million.
- At the same token count, output costs 20 times the input rate. Response length therefore deserves its own budget limit.
Audio tokens are billed at 25 tokens per second of generated speech. Preview SKUs can change before GA.
These figures use public list prices. Cache eligibility, batch or priority modes, long-context surcharges, discounts, and regional billing can change the invoice.
