About Dola Seedream 5.5 261028

Seedream 5.5

Seedream 5.5 是字节跳动 Seed 团队于 2026 年 11 月 9 日发布的多模态图像生成与编辑模型,适合商品主视觉、中文海报、人物摄影风格图片和需要反复修改的设计素材。

模型特点

  • 更稳定的多轮编辑:官方介绍支持最多 100 轮持续修改,重点改善未编辑区域的保持、色彩偏移及细节衰减。修改时可明确需要改变与保留的内容。
  • 原生 RGBA 透明背景:支持生成带 Alpha 通道的透明或半透明素材,可用于商品抠图、贴纸与设计元素;透明输出使用 PNG。
  • 更自然的真实感:改善光照、材质和皮肤纹理,减少过度油亮和过曝。
  • 更清晰的文字:提升中文复杂字形、密集小字和中英文版式的生成表现。
  • 支持文字生成、单图与多图参考编辑。API 参考资料提供最多 10 张参考图及 1K、1.5K、2K 输出档位;具体参数以所选渠道为准。

ModelSell 模型名称

主模型:dola-seedream-5-5-261028。 别名:dola-seedream-5-5-261028-ep。 两个名称均配置相同的独立计费表达式。参数量、知识截止日期和 token 上下文长度未公开,不作推测。

标准价格

美元 / 张。以下采用本站指定价格;分组倍率按所选分组另行计算。

项目价格
输入参考图片(每张,含首张)$0.00800
输出图片,≤ 2,610,000 像素(2.61 MP)$0.0200
输出图片,> 2,610,000 像素(2.61 MP)$0.0350

总费用 = 输入参考图数量 × $0.008 + 输出图片费用。纯文生图不收输入图费用。例如,一张低档输出图加一张参考图为 $0.028;一张高档输出图加两张参考图为 $0.051。按返回的实际尺寸优先判断输出档位;未返回尺寸时使用请求尺寸,未指定时按 2K 估算。生成失败不收费。

价格按本站指定的 2.61 MP 阈值配置;外部服务商的分辨率档位、折扣和接口参数不直接等同于本站渠道能力。

Use cases and prompting

调用示例

使用 API Key 的 Bearer 鉴权,向图片生成接口发送 JSON:

POST /v1/images/generations
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
{
  "model": "dola-seedream-5-5-261028",
  "prompt": "一张简洁的中文咖啡海报,奶油白背景,咖啡杯放在画面下方,标题只写早安咖啡,自然侧光,文字清晰",
  "size": "2K"
}

也可将 model 换为 dola-seedream-5-5-261028-ep,计费相同。

参考图编辑在 image 中传单张图片 URL 或 URL 数组:

{
  "model": "dola-seedream-5-5-261028",
  "prompt": "仅将背景替换为浅灰色摄影棚,保持商品形状、颜色、标识和位置不变",
  "image": ["https://example.com/product.png"],
  "size": "1K"
}

透明素材可在渠道支持时设置 background: "transparent" 和 output_format: "png"。这些示例依据模型与接口资料编写,尚未完成本站真实生成验证;可调用性及参数范围以已绑定渠道为准。

创作建议

先交代主体、构图、光照和要出现的准确文字。每轮只修改少量内容,并说明需要保留的区域;多张参考图分别写明用途。生成后检查商品结构、人物细节和文字。输入图片每张 $0.008,含首张;输出按 2.61 MP 分档,实际费用叠加所选分组倍率。
