At these rates
- A workload with 70% input and 30% output costs $1.625 per 1 million total tokens and $162.50 per 100 million.
- At the same token count, output costs 2 times the input rate. Response length therefore deserves its own budget limit.
- Filling the 1,000,000-token context window with input alone would cost about $1.25, before any output.
- Cached input is $0.2 per million, 84% below standard input when the workload meets the provider’s cache rules.
Long-context (≥200k prompt) rates: $2.50 input / $0.40 cached / $5 output per 1M tokens.
These figures use public list prices. Cache eligibility, batch or priority modes, long-context surcharges, discounts, and regional billing can change the invoice.
