How to call the Seedream 5.0 Pro API

Seedream 5.0 Pro runs through POST /v1/images/generations. The request returns a job_id right away; poll GET /v1/jobs/{job_id} until the job completes and read the output URLs from the result. Or add "sync": true to skip polling: the request stays open and returns the finished OpenAI-style image response directly, so OpenAI SDKs work as-is. Get an API key from the EmpirioLabs dashboard.

Seedream 5.0 Pro API parameters

Request parameters supported by the Seedream 5.0 Pro API on EmpirioLabs. Defaults apply when a field is omitted.

watermarkbooleanfalse-When enabled, the generated image includes an AI-generated provenance watermark. EmpirioLabs does not add a separate watermark.
output_formatenumpngjpeg, pngOutput image file format. In layer decomposition this sets the base image format, and layers are always returned as PNG.

Good to know

Modes

  • Text to image
  • Single or multi-image to image
  • Interactive editing with coordinate or sketch markers
  • Layer decomposition into a base image plus up to 16 layers

Interactive editing

Mark the region to change directly on the input image with a sketch, circle, or arrow, then describe it in the prompt. For exact placement, use coordinate tags on a 0 to 1000 normalized grid:

Place the subject from image 1 <bbox>179 283 796 986</bbox> at the position in image 2 <bbox>118 331 933 871</bbox>.

Layer decomposition

Set layer_decomposition to true with exactly one input image to split it into a base image plus up to 16 transparent PNG layers. Every returned image carries its stacking order as z_index, and each layer also carries its position in the base image as bounding_box.absolute and bounding_box.normalized, plus a name and a description. Leave the prompt empty to let the model choose the elements, or name the elements or coordinate regions to separate. Resolution accepts 1K, 1.5K, or 2K, and matches the input image when unset.

Prompt optimization

  • Standard (default): prioritizes prompt adherence and image quality
  • Fast: reduces generation latency with slightly lower image quality

Limits

  • One output image per request, except layer decomposition, which returns the base image plus its layers
  • Up to 10 reference images, and exactly one for layer decomposition or a transparent background
  • 1K, 1.5K, and 2K resolution tiers
  • PNG or JPEG output, and layers are always PNG
  • A transparent background needs one input image that already has an alpha channel, and PNG output
  • No grouped output, streaming, or web search

Billing

Layer decomposition bills every returned image, the base image and each layer, at half the standard per-image rate, tiered on the pixel count of that image.

Content safety

Generated images pass an automated content-safety check. An image flagged as explicit is not returned. Because the image is generated before the check runs, a flagged generation is still billed.

Seedream 5.0 Pro API: common questions

How much does the Seedream 5.0 Pro API cost?

On EmpirioLabs, Seedream 5.0 Pro is billed pay as you go: Output up to 2.61MP $0.075 per image; Output above 2.61MP $0.150 per image; Layer decomposition up to 2.61MP $0.0375 per image. The live rate card on this page always matches what the API charges.

Which endpoint does Seedream 5.0 Pro use?

Seedream 5.0 Pro is served through POST /v1/images/generations on api.empiriolabs.ai with standard bearer-token authentication.

Can I try Seedream 5.0 Pro in the browser before integrating?

Yes. The EmpirioLabs playground runs Seedream 5.0 Pro in the browser with the same parameters the API exposes, so you can test prompts before writing code.

How do I get a Seedream 5.0 Pro API key?

Create an EmpirioLabs account, then generate a key under API Keys in the dashboard. Billing is pay-as-you-go credits, so you only pay for the requests you make.
