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 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.
Prices are in credits. What a credit costs is on the pricing page.

About the model
FLUX 2 asks for resolution and aspect ratio up front — 1K or 2K, eight ratios — instead of guessing the format for you.

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.
