Seedream 5.0 Pro is available on EmpirioLabs. It is ByteDance's premium Seedream image model for detailed text-to-image generation, single-image edits, and multi-reference image fusion. The model launched on July 8, 2026 and is available through the OpenAI-compatible image generation endpoint.
What Seedream 5.0 Pro is good at
Seedream 5.0 Pro is built for image jobs where prompt following, text rendering, and reference control matter. Use it for product imagery, art direction, brand mockups, visual variants, and edit flows that combine details from several source images into one final output.
The model returns one image per request. It supports text-to-image, single-image-to-image, and multi-image-to-image workflows, with up to 10 reference images. Output can be PNG or JPEG, and the available resolution tiers are 1K and 2K.
How to call it
Use the standard image generation endpoint and set model to seedream-5-0-pro. This example creates a square 1K image:
curl https://api.empiriolabs.ai/v1/images/generations \
-H 'Authorization: Bearer $EMPIRIOLABS_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
"model": "seedream-5-0-pro",
"prompt": "a premium studio product photo of a matte black espresso machine on a walnut counter",
"aspect_ratio": "1:1",
"quality": "1K",
"output_format": "png"
}'For image editing or multi-reference fusion, pass image URLs in images and describe how the model should use them:
curl https://api.empiriolabs.ai/v1/images/generations \
-H 'Authorization: Bearer $EMPIRIOLABS_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
"model": "seedream-5-0-pro",
"prompt": "use the product from the first image and the lighting style from the second image",
"images": [
"https://example.com/product.png",
"https://example.com/lighting-reference.png"
],
"aspect_ratio": "16:9",
"quality": "2K"
}'Parameters to know
The main controls are aspect_ratio, quality, size, output_format, watermark, and response_format. If you need exact dimensions, use size or the custom width and height controls documented on the model page. Since this is a single-output model, there is no number-of-images control.
Generated images are returned as signed CDN URLs by default. You can request inline base64 with response_format: "b64_json" when an integration needs the image bytes in the response.
Pricing and billing
Seedream 5.0 Pro is billed per generated image, with pricing based on output size. The first reference image is included, and additional reference images add a small input-image charge. See the live Seedream 5.0 Pro model page and the pricing page for current rates.
Content safety
Image generations pass automated content-safety checks. If a generated image is flagged as explicit, it is not returned. Because the image is produced before the output check runs, a flagged generation is still billed.
Start building
Try Seedream 5.0 Pro in the EmpirioLabs playground, read the API docs, or compare it with other image models on the model catalog.
