Bytedance's Seedream 5.5 promises pixel-stable image editing across 100 rounds without color drift

Bytedance Seed introduces Seedream 5.5, an image generation model built for professional production workflows that it says supports stable multi-round editing across up to 100 rounds, preserving unchanged image areas at the pixel level without color shifts. The model generates native RGBA images with transparent backgrounds so generated elements can serve directly as design assets without manual cutouts, and Bytedance says it renders light, materials, and skin textures more realistically and reproduces dense small text more accurately. Bytedance claims Seedream 5.5 leads models like GPT Image 2.5 Sunburst in text structure and realism, and it is gradually rolling out via Jimeng, Doubao, Doubao Work, and Volcengine Ark, with a Pro version planned.
