Seedream 4.0 高质量图像生成模型
通过 model 参数选择 doubao-seedream-4-0 模型
支持文本到图像生成
异步任务管理，通过任务 ID 查询结果

重要变更：为了更好的性能和成本控制，我们不再支持在 image_urls 中直接传入 base64 图片数据。请先使用上传图片接口上传图片，获取 URL 后再调用本接口。

Authorizations

string

必填

所有接口均需要使用 Bearer Token 进行认证获取 API Key：访问 API Key 管理页面获取您的 API Key使用时在请求头中添加：

Authorization: Bearer YOUR_API_KEY

Body

string

默认值:"doubao-seedream-4-0"

必填

图像生成模型名称示例："doubao-seedream-4-0"

string

必填

图像生成的文本描述最长 1000 个字符

string

默认值:"1:1"

图像宽高比支持的宽高比：

1:1 - 正方形（默认）
4:3 - 横向 4:3
3:4 - 竖向 3:4
16:9 - 横向宽屏
9:16 - 竖向长图
3:2 - 横向 3:2
2:3 - 竖向 2:3
21:9 - 超宽屏
9:21 - 超窄屏
auto - 自动匹配参考图像比例（需要提供 image_urls）

integer

默认值:1

生成图像的数量范围：1-15（最少 1 张，最多 15 张）默认：1注意：

实际可生成的图像数量受此参数和输入参考图像数量共同影响。参考图像 + 生成图像总数必须 ≤ 15
必须输入纯数字（如 1），不要加引号，否则会报错

会根据生成数量进行预扣费

string[]

参考图像 URL 列表，用于图生图或图像编辑⚠️ 仅支持 URL 格式（不再支持 base64）

公开可访问的图像 URL（http:// 或 https://）
示例：https://example.com/image.jpg
可使用上传图片接口上传本地图片获取 URL

限制：

最多 10 张图片
图像格式：jpeg, png
宽高比（宽/高）范围：[1/3, 3]
宽度和高度（px）> 14
单张图片大小：不超过 10MB
总像素：不超过 6000×6000 px

object

渠道特有参数，用于传递 Seedream 4.0 模型的高级配置

显示 metadata 属性

string

默认值:"2K"

图像分辨率支持的分辨率：

1K - 基础分辨率
2K - 标准分辨率（默认）
4K - 高清分辨率

分辨率参考尺寸：

分辨率	1:1 尺寸	16:9 尺寸
1K	1024x1024	1280x720
2K	2048x2048	2560x1440
4K	4096x4096	5404x3040

object

提示词优化选项属性：

mode（字符串）：优化模式
- standard：标准模式，生成质量更高，处理时间更长（默认）
- fast：快速模式，处理时间更短，质量一般

示例：

"optimize_prompt_options": { "mode": "standard" }

string

默认值:"disabled"

顺序图像生成模式（豆包专属功能）控制是否生成多张图像：

disabled：禁用顺序模式，即使有多张参考图像也只生成 1 张（默认）
auto：启用顺序模式，可以生成多张图像

使用说明：

✅ 设置 n: 3 或使用 sequential_image_generation: "auto" + max_images: 3
✅ 支持文生图：仅提供文本提示词，最多生成 15 张图像
✅ 支持图生图：提供 image_urls，基于参考图像生成多张图像
⚠️ 当 n > 1 时，会自动设置为 auto

注意：

输入的参考图数量 + 最终生成图片数量 ≤ 15 张

object

顺序图像生成选项当 sequential_image_generation 设置为 auto 时可用属性：

max_images（整数）：指定生成的图像数量，范围：1-15

示例：

"sequential_image_generation_options": { "max_images": 3 }

boolean

默认值:true

是否为生成的图像添加水印

true：添加水印（默认）
false：不添加水印
