Notes

  • See Completion Windows for how to use balanced and flex for lower token prices.
    • Not all core models support all windows yet. We regularly bring up new models and expand completion window support for existing ones based on demand. If you have a need that’s not represented above, get in touch.
  • Prompt caching happens automatically and is guaranteed for all inputs with a TTL of 30 minutes.
  • See Models for capabilities and other details on supported models.

Sailbox

Notes

  • Usage accrues only while a Sailbox is running. It is measured every second and added to your bill in one-minute increments.
  • Volume storage is billed separately for each hour the volume exists, even when attached Sailboxes are sleeping, until it’s deleted.
  • For more details, see the Sailbox billing overview.
