Bytedance Seed has introduced Seedream 5.5, an image generation model it describes as built for professional production workflows. According to Bytedance, the model supports stable multi-round editing across up to 100 rounds. Unchanged image areas are preserved at the pixel level, and the company says no color shifts occur.
Seedream 5.5 can also generate native RGBA images with transparent backgrounds. Bytedance says this lets generated elements be used directly as design assets without manual cutouts.
Bytedance further claims the model renders light, materials, and skin textures more realistically. It says the model reproduces dense small text more accurately. The company also claims Seedream 5.5 leads models such as GPT Image 2.5 Sunburst in text structure and realism. The report does not include independent testing of these claims.
The model is rolling out gradually through Jimeng, Doubao, Doubao Work, and Volcengine Ark. A Pro version is planned, according to the report.
