What the price depends on

  • This model is billed per generation, so the price does not depend on how long you wait.
  • Resolution and quality settings change the price. Change one and the number above follows.
  • A generation the provider fails is not charged. A chat answer is charged for what the model wrote and thought, even if you stop it.

How a generation runs

  1. POST /v1/generate answers immediately with a job_id - it does not wait for the result.
  2. Poll GET /v1/jobs/{id} until status is completed or failed.
  3. A completed job carries output_url - the finished file.
