字节跳动 Seedream 5.5 发布：100 轮编辑不掉色，原生支持透明背景
Bytedance's Seedream 5.5 promises pixel-stable image editing across 100 rounds without color drift
字节 Seed 新出的图像模型，最多能改 100 轮还不跑色，还能直接生成带透明通道的图，官方说真实感超过了 GPT-Image-2.5 Sunburst。做电商图、设计合成的朋友可以关注，Pro 版也在路上。
字节跳动 Seed 团队推出图像模型 Seedream 5.5，主打专业生产工作流。该模型支持最多 100 轮的多轮迭代编辑，官方称全程像素稳定、不出现色彩漂移，解决多轮修改后画面逐渐失真的常见问题。
Seedream 5.5 可直接生成原生 RGBA 图像，即自带透明通道的透明背景图片，省去传统抠图环节，对电商、设计和后期合成场景更实用。字节还声称该模型在图像真实感上超过 GPT-Image-2.5 Sunburst。
定位专业用途的 Pro 版本已在计划中。这表明字节在图像生成赛道上继续对标 OpenAI 等美国厂商，重点押注多轮编辑稳定性和商用工作流能力。
