What's new in 5.5
What Seedream 5.5 does better
The four upgrades over Seedream 5.0 Pro, plus the inputs and output sizes the model supports.
Small text that stays readable
Labels, posters, menus and UI text come out sharper, in Chinese, English, Thai, Japanese and Russian. Put the exact words in quotes.
Edit in rounds without drift
Change one thing at a time: the jacket, then the background, then the light. The parts you didn't mention stay as they were.
Up to 10 reference images
Combine a product, a model, a logo and a style reference in a single edit instead of stitching separate results together.
Truer light, materials and skin
Glass, metal, fabric and skin react to light more naturally, so product and portrait shots need less retouching.
1K drafts, 3K finals
Draft at 1K, then render at 2K or 3K (about 8 megapixels) for print and large screens, in 15 aspect ratios.
