Seedream 5.0 Pro API Guide for Poster Design and Reference Image Editing
Seedream 5.0 Pro is ByteDance Seed's image generation and editing model. Use text-to-image to draft a poster with a headline and supporting copy, or use image-to-image to change the color, material, or background in a reference image. OpenAny lists both modes for seedream-5.0-pro. ByteDance Seed model overview · OpenAny model page

Quickstart
In the OpenAny Playground, select Text to image. This example drafts a portrait poster for a ceramics studio with three lines of copy. To use the API, send a POST request to https://api.openany.si/v1/images with Authorization: Bearer $OPENANY_API_KEY and Content-Type: application/json.
{
"model": "seedream-5.0-pro",
"route": { "provider": "yir" },
"route_mode": "balanced",
"input": {
"type": "text",
"prompt": "Design a portrait poster for a ceramics studio sale. Use a warm ivory background, a photograph of a cobalt ceramic bowl in the center, and generous margins. Place the exact headline 'STUDIO SALE' at the top, '20% OFF CERAMICS' beneath the bowl, and 'SATURDAY ONLY' in a small footer. Use dark navy type and keep all three lines readable. Do not add other lettering or logos."
},
"parameters": {
"resolution": "1K",
"aspect_ratio": "3:4",

}
}
Poll GET /v1/images/{task_id} using the returned task ID. When the task succeeds, retrieve the file URL from result.files. Before publishing the poster, compare all three lines against the prompt and check the spacing around the product.
Edit a reference image
In Image to image, use the same endpoint and replace the request's input with the object below. Replace the sample URL with your own publicly accessible HTTPS image. A prompt that names both the change and the details to preserve gives you a concrete way to assess the result.
{
"type": "image",
"prompt": "Recolor only the sofa upholstery to muted olive green. Preserve the sofa shape, fabric texture, seams, room lighting, and camera angle. Keep the surrounding furniture unchanged.",
"references": [
{
"role": "reference_image",
"url": "https://example.com/your-room-photo.jpg"
}
]
}
ByteDance's demo also shows interactive region selection and layer separation. The OpenAny request covered here uses a text prompt and reference image URLs. ByteDance Seed editing examples · OpenAny API and pricing
