At these rates
- A workload with 70% input and 30% output costs $11.00 per 1 million total tokens and $1,100.00 per 100 million.
- At the same token count, output costs 5 times the input rate. Response length therefore deserves its own budget limit.
- Filling the 200,000-token context window with input alone would cost about $1.00, before any output.
- Cached input is $0.5 per million, 90% below standard input when the workload meets the provider’s cache rules.
These figures use public list prices. Cache eligibility, batch or priority modes, long-context surcharges, discounts, and regional billing can change the invoice.
