What Is Seedream 5.5?

Seedream 5.5 is ByteDance’s AI image generation and editing model for turning creative ideas into detailed visuals. It combines transparent RGBA output, targeted editing, text rendering, realistic portraits and lighting control. Create isolated design assets, compose promotional graphics or refine an existing image with natural-language instructions. From the overall composition to the details of a surface or expression, Seedream 5.5 gives you more ways to shape the image around your brief.

Key Features of Seedream 5.5

Create images with a clear visual direction, then refine the details that matter—from transparent materials and typography to expression and lighting.

Transparent RGBA Image Generation

Create isolated objects, stickers and decorative elements with transparent backgrounds. RGBA output also supports semi-transparent materials, making it useful for glass, translucent surfaces and layered compositions. Build assets that fit naturally into banners, product layouts and other designs.

Precise Edits Across Multiple Revisions

Change a color, replace an accessory or refine a material with focused instructions. Seedream 5.5 supports local edits across successive revisions, helping you develop an image while retaining its overall direction. Specify what should change and which surrounding details should stay.

Detailed Text and Graphic Layouts

Bring text and imagery together in posters, infographics and multi-panel designs. Specify the wording, hierarchy and placement to guide the composition. Create layouts with a clear focal point, readable information and a visual style that fits your message.

Realistic Portraits with Natural Detail

Create expressive portraits with lifelike facial features, natural skin texture and convincing photographic detail. Guide the pose, expression and framing to suit the mood, from a relaxed lifestyle image to a close editorial portrait. Refine individual details while keeping the person recognizable.

Lighting Control for Mood and Depth

Shape the atmosphere with soft window light, directional shadows or cinematic highlights. Guide the light direction, warmth and contrast to bring out facial contours, surface textures and depth. Explore different lighting treatments for portraits, products and more elaborate scenes.
