Light and materials that read as real
Name the surfaces (linen, marble, frosted glass) and the light (a soft key from the left, a warm rim from behind). Seedream uses those cues to build depth instead of a flat studio look.

SeedreamAI image generator.
Describe the materials, the light and the space, and Seedream builds the scene. MossImage offers Seedream 5.0 Pro at 1K and 2K and Seedream 4.5 at 2K and 4K, both by ByteDance, with reference images for products you need to keep.

What you can make with Seedream
Seedream rewards a brief that describes a full arrangement instead of a list of adjectives. Say where the camera is, what sits in the foreground and what stays empty, then define materials and light. Brushed aluminium under a soft overhead light is a very different picture from glossy plastic under a hard flash, and Seedream follows those differences closely.
Seedream 5.0 Pro accepts up to 10 references and Seedream 4.5 up to 14, so you can keep a product shape or a person while changing the backdrop, the palette or the framing. On MossImage the two versions are separate choices with their own sizes and credits. For a precise change limited to one area, the editor’s One area mode switches to GPT Image 2.5 and tells you before it runs.
Strengths and controls
Two versions, different sizes
Seedream 5.0 Pro renders at 1K or 2K; Seedream 4.5 renders at 2K or 4K at a flat 10 credits. Pick 4.5 when you need a large file, 5.0 Pro for its newer rendering at web sizes.
References for what must stay
Add the product or the person as a reference and write what can change. Keep the instruction about what stays separate from the creative changes, so both are easy to check.

Ways sellers and creators use it
Product atmosphere shots
Lock the product with a reference, then change the surface, the props and the time of day for a set of lifestyle images.
Interior and space concepts
Describe the layout, materials and light of a room or a shop display. It is more reliable than stacking style names.
Banners and large prints
Use Seedream 4.5 at 4K for hero banners and print, where a bigger file matters more than speed.
How it works on MossImage
- 1
Write a focused brief
Start with one subject and a clear composition. With reference images, say what must stay and what may change. The templates below are a good starting point.
- 2
Pick the version and settings
Choose the version, shape, size above. The Generate button shows the credits before anything runs.
- 3
Review, then fix one area
Check text, faces, hands and product details. To change one part, open the image, choose One area, box it and write what should change; everything outside the box stays as it is.
Prompts to try
Product atmosphere
A ceramic coffee mug in matte sand colour on a linen tablecloth by a window. Morning light from the left, soft shadows, a sprig of eucalyptus and a folded newspaper in the background, slightly out of focus. Calm, natural, editorial photo.
Surfaces and light first; mood words last.
Use this promptShop display concept
A small skincare shop display: three amber glass bottles on a curved travertine plinth, a pale green wall behind, a soft spotlight from above. Wide shot with room on the left for text. No logos.
Say where the empty space goes if you will add text later.
Use this promptIdeas from the MossImage gallery
We have not published Seedream examples yet. These gallery images were made with other models, named on each card; use their prompts as a starting point.
Before you generate
- Check text, faces, hands, logos and product details on every result before you publish it.
- Only upload photos you have the right to use, and say clearly what must stay the same.
- Settings come from the menus, not the prompt: writing “4K” in a prompt does not change the output size.
- Uploads and results are private to your account and not indexed. Failed jobs are refunded automatically.
Seedream questions
Which Seedream versions are on MossImage?
Seedream 5.0 Pro and Seedream 4.5, both by ByteDance. 5.0 Pro renders at 1K or 2K and takes up to 10 references; 4.5 renders at 2K or 4K and takes up to 14.
Should I start at 4K?
Check the composition first at a smaller size, then rerun the version you like at the size you need. 4K is available on Seedream 4.5 only.
Can Seedream edit my photo?
Yes, as a whole-image edit: upload a photo, describe the change, and the whole picture can be redrawn. To change only boxed areas and keep the rest identical, use One area in the editor, which runs on GPT Image 2.5.
Can Seedream write text in the image?
It can render short text you put in quotes, but results vary. For posters with exact wording, compare with GPT Image 2.5 or MOSS-Image, and always proofread before publishing.
How much does Seedream cost?
Seedream 5.0 Pro costs 11 credits at 1K and 23 at 2K. Seedream 4.5 costs 10 credits at 2K or 4K. The total is shown before you confirm, and failed jobs are refunded.
