How much does one image cost?

It depends on the settings. The exact price is on the button before you start, and it updates with every change.

What if it doesn't work out?

If the run fails at the provider, no credits are charged. If the result is ready but you don't like it, press “Edit and retry”: the prompt and settings stay.

Can I use my own picture?

Yes: add up to 1 — from your computer, from the Library or as an element. The model takes them as a base or a reference.

How is Flux Kontext Dev different from Flux 2?

Both are in the Black Forest Labs line-up. Switch between them in the line-up at the top of the page — the price of each is on its card.

Where are the results kept?

Every finished result goes to your Library. From there you can download it, publish it in the Community or use it as the base for the next one.

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 for every model Top up

For developers

Run this from your own code

The same request the Generate tab sends, with the settings you have chosen.

Model id:flux-kontext-dev

curl -X POST https://seedara.ai/api/v1/generate \
  -H "Authorization: Bearer $SEEDARA_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
  "model": "flux-kontext-dev",
  "prompt": "Describe the image: subject, style, framing, lighting...",
  "params": {
    "output_format": "jpeg"
  }
}'

This snippet updates as you change the form. Copy it once the settings are the ones you want.

Request parameters

What goes in `params`, by the names the API uses.

Required

The model refuses the request without these.

Parameter	Type	Accepted values	Default
`image_urls` Input images	images	up to 1 files	—

Optional

Left out unless you set them - the provider then applies its own default.

Parameter	Type	Accepted values	Default
`output_format` File format	one of a list	`jpegpng`	jpeg

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.

curl https://seedara.ai/api/v1/jobs/JOB_ID \
