Price
Reference price
No published price yet - this model is not in the public price list.
What the price depends on
- This model is billed per second of output, so length is the biggest lever on the price.
- 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.
Prices are in credits. What a credit costs is on the pricing page.

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