字节跳动 Seed 发布 Seedream 5.5 图像生成模型
Bytedance's Seedream 5.5 promises pixel-stable image editing across 100 rounds without color drift
字节跳动 Seed 发布面向专业生产工作流的图像生成模型 Seedream 5.5，称其支持最多 100 轮多轮编辑，未改动区域在像素级保持一致且不出现偏色。该模型可原生生成带透明背景的 RGBA 图像，无需手动抠图即可作为设计素材使用，并称在光照、材质与皮肤质感上更真实、密集小字还原更准确。

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.
