Overview
What is Seedream?
Seedream is ByteDance's advanced image generation model, designed for professional workflows requiring exceptional quality and precise control. It features a unified architecture that handles both generation and editing seamlessly—the same model that creates your images can also refine them, ensuring consistent quality throughout your workflow.
Seedream 4.5 is the flagship version, supporting up to 14 reference images simultaneously for complex multi-reference workflows.

Both versions offer broad creative freedom for diverse artistic expressions. Whether you're creating stylized portraits, conceptual art, or expressive character designs, Seedream provides the flexibility to explore your vision without unnecessary restrictions. The model excels at maintaining character identity across poses and scenes.
