At these rates
- A workload with 70% input and 30% output costs $0.285 per 1 million total tokens and $28.50 per 100 million.
- At the same token count, output costs 4 times the input rate. Response length therefore deserves its own budget limit.
- Filling the 262,144-token context window with input alone would cost about $0.03932, before any output.
- Cached input is $0.015 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.
