Bytedance has introduced Seedream 5.5, an image generation model designed for professional production workflows. The system claims to support stable multi-round editing across up to 100 iterations while preserving unchanged image areas at the pixel level without colour shifts. It also generates native RGBA images with transparent backgrounds, allowing generated elements to function directly as design assets without manual cutouts. Bytedance states the model renders light, materials, and skin textures more realistically and reproduces dense small text more accurately than competitors.
These features address specific pain points in iterative design where previous models often drifted in style or failed to maintain structural integrity over many edits. Pixel-level stability reduces the time designers spend correcting artefacts, while native transparency streamlines the integration of AI outputs into existing graphic files. The model is currently rolling out via Jimeng, Doubao, Doubao Work, and Volcengine Ark, with a Pro version planned for later release.
- Supports up to 100 consecutive edit rounds without visual degradation
- Outputs native RGBA files with transparent backgrounds
- Improves accuracy in rendering small text and physical textures
