Seedream 4.5

What is Seedream 4.5?

Seedream 4.5 was developed specifically to address the biggest limitation of its predecessor: human subjects. While Seedream 4.0 excels at environments and textures, version 4.5 introduces a retrained anatomy module that dramatically improves how the model renders people. Faces are more expressive and proportionally accurate, hands are rendered with correct finger counts and natural poses, and body proportions follow realistic anatomy even in unusual poses or camera angles. The model retains the rich visual warmth and painterly quality of the Seedream aesthetic but applies it to human subjects with a slightly stylized, editorial look — think fashion photography with an artistic edge rather than strict photorealism. Skin tones are rendered with natural warmth and subsurface scattering effects, and hair catches light realistically. Portrait photographers, fashion content creators, and illustrators working on character-driven projects will find Seedream 4.5 particularly valuable as a bridge between the atmospheric strengths of 4.0 and the all-around capability of 5.0.
