Why creators pick Seedream
Text that actually renders
Posters, packaging, UI mockups — Seedream draws readable, correctly-spelled text where most image models produce mush.
Edits that hold together
Change a color, swap a background, restore a photo — edits stay consistent with lighting and identity instead of repainting the whole image.
4K, social-ready formats
Portrait, landscape, square — pick the ratio and get print-grade resolution.
Same prompt, other engines

What is Seedream?
Seedream is ByteDance's family of AI image generation models. From a text prompt or a reference image, Seedream produces high-resolution images — and it is best known for two things competing models struggle with: rendering readable text inside images (posters, UI mockups, infographics) and making targeted edits without breaking the rest of the picture.
ByteDance publishes Seedream through its Seed research lab and ships it inside its own apps; there is no standalone consumer website for the model itself. That's where hosted platforms come in.
SeedDance gives you Seedream in the browser: type a prompt, pick an aspect ratio, download the result. First images are free with no account.
