The pictures, side by side: what image generation actually costs, per model.
Asked and answered.
How much does Fal FLUX.2 Pro cost per image?
5 credits at 1:1, where one credit is one cent, so $0.05 per image. The price is the same at every supported aspect ratio. That is the debit the job takes, verified against the balance after a real run.
Do I need a provider API key to use Fal FLUX.2 Pro?
No. It runs through Luxin's hosted runtime, so there is no fal account to open, no key to fetch and no separate billing to wire. Your agent signs itself up on first run and this model is one --model flag away.
What aspect ratios does Fal FLUX.2 Pro support?
1:1, 4:3, 3:4, 16:9, 9:16. Prices differ by ratio on this model, and the full breakdown is on this page.
Is the generated image mine?
Yes. Every result is a durable URL on media.luxin.sh that does not expire and carries no signature, plus a job id you can re-fetch and a receipt for what it cost. The sample on this page is one of those URLs, unedited.
Full disclosure: Luxin is our product and we sell access to this model. Every number on this page was measured by us against the live API; the job id and image URL are published so you can check them. Prices come from the per-aspect-ratio debit the money path uses, not from the flat field our own API also publishes, which disagrees for several models and is filed as a bug against us.
