Seedream 5.0 Pro examples
Three images generated with Seedream 5.0 Pro on Wan API on October 23, 2026, each at a 2K size with the watermark off. Each prompt is shown exactly as sent.
Festival poster with exact text
The headline, the date line and all three performer names came out spelled exactly as written, in a clear typographic hierarchy.
Prompt · 1728x2304
An editorial poster for a jazz festival, portrait 3:4. A brass saxophone player silhouetted against a deep cobalt night sky, warm amber stage lights spilling from below, smoke drifting through the beams. Bold condensed serif headline "BLUE HOUR JAZZ" across the top, a smaller line "Lisbon · 14–16 August 2026" beneath it, and three performer names in a clean grid at the bottom: "Mara Quintela", "Kenji Arai Quartet", "The Delta Trio". Risograph print texture, generous margins, strong contrast.
Product campaign shot
Hard side light, an amber caustic on wet stone and room on the right for copy, following each part of the brief.
Prompt · 2560x1440
Luxury campaign photograph of a faceted amber glass perfume bottle with a brushed gold cap, standing on wet black volcanic rock at the edge of the sea. A single shaft of hard morning light from the left catches the facets and throws a warm amber caustic onto the stone. Fine water droplets on the glass, ocean mist softening the dark background, shallow depth of field, deep charcoal and gold palette, 16:9 hero image with empty space on the right for copy.
App landing page layout
Navigation, headline, button and phone mockup follow the requested layout and text. Small stray marks remain inside the phone screen background.
Prompt · 2560x1440
A 16:9 landing page design for a plant-care app called "Leafline". Top navigation bar with the Leafline logo and links "Features", "Pricing", "Journal".

Soft sage, cream and deep forest green palette, clean sans-serif typography, subtle shadows, generous whitespace.
Pricing
Seedream 5.0 Pro pricing
Seedream 5.0 Pro is billed per output image at 30% below the official rate. Outputs up to 2.61 million pixels (1K and 1.5K) use the lower rate, larger outputs the higher rate. The first reference image is free; each additional reference adds a small charge.
Seedream 5.0 Pro at 1K
$0.0315 per image
1.5K costs the same as 1K. Review the composition before choosing 2K.
Live ratesUSD per image
| Billed item | Official price | Wan API price |
|---|---|---|
| Image up to 2.61 MP (1K, 1.5K) | $0.045 | $0.0315 |
| Image above 2.61 MP (2K) | $0.09 | $0.063 |
| Layer decomposition, every returned image up to 2.61 MP | $0.0225 | $0.01575 |
| Layer result with a larger image: each image up to 2.61 MP | $0.0225 | $0.0225 |
| Layer result with a larger image: each image above 2.61 MP | $0.045 | $0.045 |
| Each reference image after the first | $0.003 | $0.0021 |
Wan API sells Seedream 5.0 Pro images, extra references and 1K or 1.5K layer decomposition at 30% below the official per-image price. A layer result that includes an image above 2.61 MP is charged at the official rate.
Layer decomposition charges the base image and each returned layer. When every returned image is up to 2.61 MP, each costs the discounted layer rate; when any image is larger, every image is charged at the official layer rate for its own size. The estimate covers the maximum of 17 images.
Official prices: BytePlus ModelArk. Checked 2026-10-23.
Layer decomposition charges the base image and each returned layer. When every returned image is up to 2.61 MP, as is usual at 1K and 1.5K, each costs 30% below the official layer rate; a result that includes a larger image, as 2K always does, is charged at the official layer rate. Requests rejected before an image is generated are not charged.
Readme
What is Seedream 5.0 Pro?
Seedream 5.0 Pro is ByteDance's image generation model for single-image output. It accepts a prompt alone, one reference image for editing, or 2 to 10 reference images that are combined into one new image. Prompts work in English and Chinese, and also in Japanese, Korean, French, German, Spanish and other languages.
Layer decomposition takes one PNG or JPEG image and returns a base image plus up to 16 layers. Each layer is a PNG with an alpha channel, with its stacking order, bounding box, name and description. Transparent background mode turns one image that already has an alpha channel into a new transparent PNG.

Model ID
bytedance/seedream-5.0-proUse this ID in the model field. Each request returns one image, or one base image plus its layers in layer decomposition mode.
Two ways to use Seedream 5.0 Pro
Connect your backend
Send the Playground JSON to POST /v1/images/generations with your Wan API key. The response returns the image URLs directly in the OpenAI Images format. The API guide has request and response examples.
Give your coding agent the contract
Share the Seedream 5.0 Pro OpenAPI document with your coding agent. Ask it to validate sizes and reference counts and to send each request once.
Create with Seedream 5.0 Pro
Edit one image
Send one image with a focused instruction: change a background, material or color while naming the details to keep.
Combine references
Seedream 5.0 Pro accepts up to 10 references. Say what each image contributes: subject, product, setting or style.
Split into layers
Turn one image into a base image and up to 16 transparent PNG layers. Name the elements to separate, or leave the prompt empty to separate the main elements automatically.
Keep transparency
With one input image that has an alpha channel, background transparent returns a PNG with a real transparent background.
Trade speed for quality
Standard prompt optimization favors quality. Fast mode shortens generation time with slightly lower quality.
Where Seedream 5.0 Pro fits
Posters and covers
Put the exact headline in quotes for covers, posters and social graphics that need readable text. Check spelling before publishing.
Product sets
Combine a product photo with scene or style references to produce consistent campaign images. Compare labels and shapes with the real product.
Editable design files
Split a finished image into layers so text, subjects and background can be moved or replaced in a design tool.

Choose your Seedream 5.0 Pro workflow
| Workflow | When to use |
|---|---|
| Text to image | Use no references when you are exploring a new scene and do not need to keep an existing subject. |
| Single image edit | Send one reference when the starting picture matters. State the change and the details to keep. |
| Multiple references | Send 2 to 10 images when the result needs distinct ingredients, and give each one a clear role. |
| Layer decomposition | Send exactly one PNG or JPEG image when you need separate, editable layers rather than a new picture. |
| Transparent background | Send exactly one image with an alpha channel when the result must keep a transparent background. |
Seedream 5.0 Pro limits
One image per request
Each request returns one image. Send separate requests for variations; layer decomposition returns one base image plus its layers.
Size range
Choose 1K, 1.5K or 2K, or an exact size of 921,600 to 4,624,220 pixels with an aspect ratio between 1:16 and 16:1.
Layers are all or nothing
Layer decomposition outputs at most 16 layers. If any layer fails, the whole request fails.
Not available on this model
Group generation, web search and streaming are not supported by Seedream 5.0 Pro.

Seedream 5.0 Pro FAQ
What resolutions does Seedream 5.0 Pro support?
Choose 1K, 1.5K or 2K, or an exact width x height between 921,600 and 4,624,220 pixels with an aspect ratio from 1:16 to 16:1. Layer decomposition uses 1K, 1.5K, 2K or auto, which follows the input image.
When was Seedream 5.0 Pro released?
ByteDance announced Seedream 5.0 Pro on July 8, 2026. On Wan API it is available as bytedance/seedream-5.0-pro through the OpenAI Images API.
How much does Seedream 5.0 Pro cost?
Each output image up to 2.61 million pixels costs the lower rate and larger images the higher rate, as shown in the pricing table. The first reference image is free and each additional one adds a small charge. Layer decomposition bills the base image and every returned layer: at the discounted layer rate when every image is up to 2.61 million pixels, and at the official layer rate when the result includes a larger image.
How many reference images can I use?
Up to 10 reference images per request. Layer decomposition and transparent background mode each take exactly one image.
What does layer decomposition return?
A base image plus up to 16 layers. Every layer is a transparent PNG with its z-index, bounding box, name and description, so it can be rebuilt in a design tool.
Can Seedream 5.0 Pro create a transparent background?
Yes, from one input image that already has an alpha channel. Set background to transparent and keep PNG output; JPEG output cannot be combined with it.
Does Seedream 5.0 Pro add a watermark?
The official default adds a small AI-generated watermark. Set watermark to false to turn it off.
