Pricing tiers: Daybreak approval and provisioning are required. Input/output $12.50/$75 per million tokens; cache reads $1.25 and writes $15.625. The model card states full-request 2x input and 1.5x output above 272K input, while the central pricing table leaves long-context cells unpublished; confirm the approved account terms before such use.

Best for

  • Authorized vulnerability research
  • Exploit validation
  • Defensive security testing

Watch out

Separate Daybreak Red approval/provisioning is required; a spend tier alone does not grant access. This is a moving purpose-trained cybersecurity alias, with no dated snapshot, underlying release day, selectable effort enum or comparable benchmark set established. The card supports streaming, function calls and structured outputs; fine-tuning is unsupported. Responses tools are documented separately from native text/image inputs and text output; tool image generation does not make this an image-output model.
