For tool-specific models, like search and computer use, there’s a fee per tool call. See details in the pricing page.Text tokensPer 1M tokensInput$1.00Cached input$0.05Cache writes$1.25Output$5.00

Cached input tokens are priced at 5% of the uncached input token rate.

Cache-write prices shown use 30-minute retention. Standard cache writes cost $1.25 per million tokens for 30-minute retention and $2.50 for 12-hour retention, before long-context adjustments.

Prompts with more than 272K input tokens are priced at 2x input and cache rates and 1.5x output for the full request.

Batch and Flex prices are 50% lower than Standard.

Regional processing adds a 10% premium where available.

Fast mode prices are 2x Standard.
