ByteDance Seed has introduced Seedream 5.5, an image-generation model aimed at production work that requires repeated edits and reusable design assets.
The company says unchanged portions of an image can remain stable at the pixel level through as many as 100 editing rounds without color drift. That addresses a common problem in generative editing, where changing one object can unintentionally alter lighting, colors or details elsewhere in the frame.
Seedream 5.5 also produces native RGBA images with transparent backgrounds, allowing generated objects to move directly into design layouts without a separate cutout step. ByteDance claims improvements in light, materials, skin texture and small, dense text, and says the model leads GPT Image 2.5 Sunburst on text structure and realism.
Those comparisons come from ByteDance, and the announcement does not provide enough independent testing to establish how consistently the model preserves pixels across varied professional workloads. Seedream 5.5 is gradually rolling out through Jimeng, Doubao, Doubao Work and Volcengine Ark. A Pro version is planned, but the report does not specify its release date, price or differences from the current model.
