seedream-5-0-pro/v1/images/generationsLive pay-as-you-go rates from the EmpirioLabs catalog. You are billed only for what you use, with no monthly minimum.
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.

time.sleep(5)Request parameters supported by the Seedream 5.0 Pro API on EmpirioLabs. Defaults apply when a field is omitted.
| Parameter | Typ | Standard | Bereich / Werte | Beschreibung |
|---|---|---|---|---|
| prompt | string | - | - | Text prompt. With image attached, becomes an editing or fusion instruction. |
| image | array | - | - | Reference image URL, data URI, or uploaded image object. Seedream 5.0 Pro supports up to 10 reference images. |
| images | array | - | - | Alias for image. Use this for multiple uploaded image references. |
| aspect_ratio | enum | auto | auto, 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9 | Auto lets the model choose dimensions within the selected resolution tier. Explicit ratios use the preset size for that tier. |
| quality | enum | 2K | 1K, 2K | Seedream Pro resolution tier. Defaults to 2K. |
| size | string | - | - | Resolution tier or explicit pixel size such as 1K, 2K, or 2048x2048. Explicit pixels override aspect_ratio and quality. |
| use_custom_size | boolean | false | - | Use custom_width and custom_height instead of preset aspect_ratio and quality. |
| custom_width | number | - | 16 to 8192 | Custom output width in pixels. Total area must be in [0.92MP, 4.19MP], aspect must be in [1:16, 16:1], and dimensions must be multiples of 16. |
| custom_height | number | - | 16 to 8192 | Custom output height in pixels. Total area must be in [0.92MP, 4.19MP], aspect must be in [1:16, 16:1], and dimensions must be multiples of 16. |
| watermark | boolean | false | - | When enabled, the generated image includes an AI-generated provenance watermark. EmpirioLabs does not add a separate watermark. |
| output_format | enum | png | jpeg, png | Output image file format. |
| response_format | enum | url | url, b64_json | Return signed image URLs by default, or include base64 image data when b64_json is requested. |
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.
On EmpirioLabs, Seedream 5.0 Pro is billed pay as you go: Output up to 2.36MP $0.075 per image; Output above 2.36MP $0.150 per image; Extra input image $0.005 per input image after the first. The live rate card on this page always matches what the API charges.
Seedream 5.0 Pro is served through POST /v1/images/generations on api.empiriolabs.ai with standard bearer-token authentication.
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.
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.
