An image model built for multi-round editing
Grounded in available product and source data
Seedream 5.5 is a multimodal image generation model from ByteDance, built around the idea that most image work is a sequence of adjustments rather than a single prompt. You can change one region across many rounds and the parts you did not touch stay where you left them.
That makes it useful for iterative work. Furniture, lighting and decor can be added or replaced, and hair, eyewear, outfits and props can be refined while perspective and lighting stay coherent. The model also handles transparent output, so a subject can be generated on its own RGBA layer, and sticker sets can be produced with the background left clear.
