字节跳动 Seedream 5.5 图像模型主打 100 轮像素级稳定编辑
Bytedance's Seedream 5.5 promises pixel-stable image editing across 100 rounds without color drift
字节跳动 Seed 发布图像生成模型 Seedream 5.5，官方称支持最多 100 轮多轮编辑，未改动区域可像素级保持且无色彩漂移。模型还能生成带透明背景的原生 RGBA 图像，官方称在光线、材质、皮肤纹理和小文字渲染上更真实，并称在文字结构上领先 GPT Image 2.5 Sunburst；模型正通过即梦、豆包、豆包 Work 和火山引擎 Ark 逐步推出，计划提供 Pro 版本。
Bytedance Seed introduces Seedream 5.5, a new image generation model built for professional production workflows. According to Bytedance, one improvement is stable multi-round editing across up to 100 rounds, with unchanged image areas preserved at the pixel level and no color shifts. The new Flux model also stood out here recently.
Seedream 5.5 also generates native RGBA images with transparent backgrounds, letting generated elements serve directly as design assets without manual cutouts. Bytedance says the model renders light, materials, and skin textures more realistically and reproduces dense small text more accurately.
Bytedance claims Seedream 5.5 leads models like GPT Image 2.5 Sunburst in text structure and realism. The model is gradually rolling out via Jimeng, Doubao, Doubao Work, and Volcengine Ark. A Pro version is planned.
