How the estimate is calculated

Standard input tokens are billed at $1.00 per million, cached input at $0.10 per million, and output tokens at $5.00 per million.

monthly cost = 30 × requests/day × (input cost + cached input cost + output cost)

What this estimate excludes

Provider account tiers, regional taxes, tool calls, storage, fine-tuning, data transfer, and other product-specific charges are excluded unless explicitly represented in the calculator.

Pricing notes

  • Cached input represents a cache read; 5-minute and 1-hour cache writes cost $1.25 and $2 per million tokens.
  • The recorded price is for the first-party global endpoint; Batch and third-party cloud pricing are excluded.
