Doubao Seedream 生成图像 API

Doubao Seedream 系列通过统一图像生成入口发起请求，适合文生图，也支持通过 image 数组传参考图做图生图。

统一入口为 POST /v1/images/generations。
model 传具体 Seedream 型号即可。
size 直接传像素尺寸字符串，例如 2048x2048、2560x1440。
image 支持图片 URL 或 Base64 数组，适合图生图和多参考图场景。
返回通常兼容 OpenAI Images 风格，常见为 url 或 b64_json。

当前可用模型

  ]
}

认证

Authorization: Bearer YOUR_API_KEY

Body

model

string

required

Doubao Seedream 模型名称。常见值包括 doubao-seedream-4-0-250828、doubao-seedream-4-5-251128、doubao-seedream-5-0-260128。

prompt

string

required

生成提示词。文生图和图生图都建议显式传入。

integer

生成数量。该字段可选；建议显式传 1，便于获得稳定的返回结构。

size

string

输出尺寸，直接传宽高像素值。Doubao 这组模型通常按固定比例映射到固定像素尺寸。

image

array<string> | string

可选参考图输入。支持图片链接或 Base64 数组，图生图时把参考图放进这个字段。

response_format

string

可选返回格式。常见值为 url、b64_json。若不传，最终返回格式取决于模型和渠道能力。

quality

string

质量字段。接口可接收该字段，是否生效取决于具体 Doubao 模型和渠道能力。

style

string | object

风格字段。接口可接收该字段，是否生效取决于具体 Doubao 模型和渠道能力。

background

string | object

背景控制字段。接口可接收该字段，是否生效取决于具体 Doubao 模型和渠道能力。

watermark

boolean

显式水印开关。false 与不传语义不同：显式传 false 表示关闭水印，不传则使用默认策略。

尺寸映射

Doubao 这组模型通常按宽高比映射到固定像素尺寸，可按下表使用：

宽高比	`size` 值
`1:1`	`2048x2048`
`4:3`	`2304x1728`
`3:4`	`1728x2304`
`16:9`	`2560x1440`
`9:16`	`1440x2560`
`3:2`	`2496x1664`
`2:3`	`1664x2496`
`21:9`	`3024x1296`

和 Gemini 不同，Doubao 这组接口不是传“比例枚举”，而是把比例映射成具体像素尺寸，再把该尺寸写入 size。

文生图 vs 图生图

场景	关键字段	说明
文生图	`prompt` + `size`	最基础写法
图生图	`prompt` + `size` + `image`	`image` 可放一张或多张参考图

Response

created

integer

生成时间戳。

data[].url

string

返回图片 URL。

data[].b64_json

string

返回图片 Base64 数据。

data[].revised_prompt

string

部分上游会返回调整后的提示词。

异步调用

Doubao Seedream 系列也支持通过异步入口提交任务：

POST /v1/images/generations/async

请求体字段与本页同步生图基本一致，model 可以传 doubao-seedream-4-0-250828、doubao-seedream-4-5-251128 或 doubao-seedream-5-0-260128。提交成功后读取返回的 id / task_id，再通过 GET /v1/images/generations/async/{taskId} 查询状态和结果。
