Seedream 5.5 is now available in ComfyUI via Partner Nodes. It is a multimodal model: it generates from text, and it edits from images.
This release moves in five directions. Transparent RGBA generation. Precise localized editing that holds up across multiple rounds. Posters and infographics with readable text and structured layouts. More realistic portraits. Lighting control.
In ComfyUI, all of it sits behind one node. Wire it into an existing graph, chain edits, and send transparent outputs straight to your compositing nodes.
Model Highlights
Multi-turn editing. Make a targeted change, then another, then another. Seedream 5.5 edits the region you describe and leaves the rest of the frame alone, round after round. Swap furniture in an interior, update the numbers on a watch face, rework a hairstyle. Layout, perspective, and lighting carry through.
Localized control. Change an object’s color, shape, or material without regenerating the whole image.
Transparent output in one step. Seedream 5.5 generates RGBA natively, with support for both transparent and semi-transparent backgrounds. Stickers, lettering, character cutouts, and product elements come out ready to layer. It can also pull a subject out of an existing image onto its own transparent layer.
Posters and infographics. Text rendering and structured layouts in the same pass. Multi-panel designs come out with a clear information hierarchy and coordinated color.
Photographic detail. More natural lighting, finer material rendering, and more convincing skin texture. Portraits and candid street scenes hold up at full size.
Lighting control. Direct the light in the prompt, from flash-lit snapshots to golden-hour interiors.
