At these rates

  • A workload with 70% input and 30% output costs $0.515 per 1 million total tokens and $51.50 per 100 million.
  • At the same token count, output costs 6.25 times the input rate. Response length therefore deserves its own budget limit.
  • Filling the 400,000-token context window with input alone would cost about $0.08, before any output.
  • Cached input is $0.02 per million, 90% below standard input when the workload meets the provider’s cache rules.
