Preview
Built to keep your image stable through every revision
In BytePlus internal testing, Seedream 5.5 held up through more than 30 rounds of local editing, with untouched areas staying stable. Its multilingual text score rose to 4.53 from 3.34 for Seedream 5.0 Pro, measured across 15 languages. These are preview figures; APIXO specifications and pricing arrive at launch.
Capabilities
What the preview aims to improve
Areas BytePlus highlights in the Seedream 5.5 preview, compared with Seedream 5.0 Pro.
Repeat local edits
Change one part of an image, then the next, while the rest stays put. BytePlus reports more than 30 clean edit rounds in internal testing.
Multilingual text
Headlines, labels and small print render more legibly across 15 languages. Proofread names and key copy before you publish.
Text-rich layouts
Posters, menus and infographics keep text and layout together in a single brief. Spell out the exact words and their order in your prompt.
Lighting
Light direction and shadows follow the scene more convincingly. Describe where the light comes from to set the mood.
Materials and skin
Glass, metal, fabric and skin show finer surface detail. Check reflections and close-up texture at full size.
Transparent assets
The preview describes fully and partly transparent output for stickers, logos and cut-outs. Place the file over a contrasting color to check the edges.
Use cases
Better images, with consistency that lasts
A step up from Seedream 5.0 Pro in image quality
The Seedream 5.5 preview builds on Seedream 5.0 Pro with more natural lighting, finer material detail and more lifelike skin. Reflections on a product, the weave of a garment and the shadows in a portrait help the whole image feel more convincing. For campaign visuals and product images, that means a more polished starting point for your final design.
30 edits to one image, with untouched areas staying consistent
Change a color, then a material, then an accessory: the Seedream 5.5 preview highlights consistency across 30 successive edits to the same image. Areas you do not ask to change retain their appearance, so refining one detail does not mean rebuilding the rest. Keep the face, product shape and composition you already like while working toward the final version.
Product campaigns
Start from a product shot and revise the background, props and headline in separate edits. The product itself stays the same from round to round.
Posters and infographics
Brief the headline, sections and language, and get a layout where the text is part of the design. Proofread every line before it goes out.
Scene changes
Upload a reference and change the setting, season or lighting. The subject keeps its look while the scene around it changes.
