Product and campaign concepts
Generate a clean product scene from text, or upload a product photo in urls and describe a background or lighting change. Compare the edited item with the source before using it in a listing.
Explore a room color or visual direction
Start at 1K with one room reference and change one surface at a time. Keep the original photo for every attempt so an earlier edit does not become the next reference.

Alternatives

Seedream 5.0 Lite
Choose Lite when you need its 3K or 4K output options, or want to compare its 2K tariff. Pro currently offers 1K and 2K; the name does not imply a larger maximum output.

What does Seedream 5.0 Pro cost with reference images?

The first reference image is included in the generation tariff. Each additional reference adds $0.004. Total = resolution tariff + max(0, reference count − 1) × reference_image tariff. USD examples use the current catalog; the playground estimates your actual request.

Request configurationCost (USD)
1K image, zero or one reference$0.04
2K image, zero or one reference$0.079
2K image, three references$0.087

Get your first result

  1. Create an account and API key. Keep the key on your server, outside browser code.
  2. Top up your balance to cover the request price.
  3. Use the playground or the API quick start above. For a first result, use the text-only request shown above. To edit a product photo, add its URL in input.urls and describe what should change and what should stay. Check labels, logos and fine details in the result before publishing. Use input.urls for Seedream references, not the imageUrls field used by some video models.

Check progress with the returned taskId. Creating a new task charges for another request.

The task response reference covers results, errors and webhooks.

Limits and test notes

  • Pro accepts 1K and 2K output here; a 4K request is not a Pro option. Check the returned file dimensions rather than treating a resolution label as a fixed width and height.
  • A reference guides the edit but does not lock product details, lettering or room fixtures. Keep critical text and unchanged product pixels in a separate compositing workflow when exact preservation is required.
  • We have not published a recorded Seedream Pro output test on this page. The use cases are starting workflows, not measured evidence of detail preservation or a Pro-versus-Lite quality ranking.
