Authorizations
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
单图模型:
doubao-seedream-5-0-pro 每次请求仅生成 1 张图像,质量优先。以下参数不受支持,传入会被拒绝(返回 400):n > 1(组图数量)
Body
图像生成模型名称支持的模型:
doubao-seedream-5-0-proExample: "doubao-seedream-5-0-pro"图像生成的文本描述
建议: 控制在 600 英文单词以内,描述过长可能导致细节丢失。
图像生成的宽高比支持的宽高比:
1:1- 正方形(默认)4:3- 横向 4:33:4- 纵向 3:416:9- 横向宽屏9:16- 纵向竖屏3:2- 横向 3:22:3- 纵向 2:321:9- 超宽屏auto- 由模型根据 prompt / 参考图自动决定宽高比
注意: 不支持自定义像素值;列表外的取值(如 9:21)会被直接拒绝,返回 400。
图像分辨率支持的分辨率:
1K- 标准分辨率2K- 高清分辨率(默认)
注意: doubao-seedream-5-0-pro 仅支持 1K 和 2K,传入 3K / 4K 等档位会返回 400。

参考图像的 URL 列表,用于单图 / 多参考图生图,最多 10 张支持两种格式:1. 完整的图像URL地址
- 公开可访问的图像URL(http:// 或 https://)
- 示例:
https://example.com/image.jpg
- 必须使用完整的 Data URI 格式
- 格式:
data:image/{格式};base64,{base64数据} - 示例:
data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABg... - ⚠️ 注意:必须包含
data:image/jpeg;base64,前缀部分
- 图片格式:jpeg、png、webp、bmp、tiff、gif、heic、heif
- 宽高比(宽/高)范围:[1/16, 16]
- 宽高长度(px)> 14
- 单张图片大小:不超过 30MB
- 总像素:不超过 6000×6000 px
计费: 单次请求中,第一张参考图免费,之后每张参考图额外计费。
输出图片格式
jpeg:JPEG 格式(默认)png:PNG 格式,适用于需要透明背景等场景
兼容:response_format与output_format等价,其余取值按jpeg处理。
是否在生成的图像右下角添加 “AI generated” 水印
true:添加水印false:不添加水印(默认)
⏱️ 生成较慢:1K 约 90 秒、2K 约 160 秒(Pro 模型质量优先)。提交后每 5~10 秒轮询一次
GET /v1/tasks/{task_id},建议客户端轮询超时设为 5 分钟。任务失败会自动全额退款。Response
