Seedream 4.0 高質量圖像生成模型
通過 model 參數選擇 doubao-seedream-4-0 模型
支持文本到圖像生成
異步任務管理，通過任務 ID 查詢結果

重要變更：爲了更好的性能和成本控制，我們不再支持在 image_urls 中直接傳入 base64 圖片數據。請先使用上傳圖片接口上傳圖片，獲取 URL 後再調用本接口。

Authorizations

string

必填

所有接口均需要使用 Bearer Token 進行認證獲取 API Key：訪問 API Key 管理頁面獲取您的 API Key使用時在請求頭中添加：

Authorization: Bearer YOUR_API_KEY

Body

string

預設值:"doubao-seedream-4-0"

必填

圖像生成模型名稱示例："doubao-seedream-4-0"

string

必填

圖像生成的文本描述最長 1000 個字符

string

預設值:"1:1"

圖像寬高比支持的寬高比：

1:1 - 正方形（默認）
4:3 - 橫向 4:3
3:4 - 豎向 3:4
16:9 - 橫向寬屏
9:16 - 豎向長圖
3:2 - 橫向 3:2
2:3 - 豎向 2:3
21:9 - 超寬屏
9:21 - 超窄屏
auto - 自動匹配參考圖像比例（需要提供 image_urls）

integer

預設值:1

生成圖像的數量範圍：1-15（最少 1 張，最多 15 張）默認：1注意：

實際可生成的圖像數量受此參數和輸入參考圖像數量共同影響。參考圖像 + 生成圖像總數必須 ≤ 15
必須輸入純數字（如 1），不要加引號，否則會報錯

會根據生成數量進行預扣費

string[]

參考圖像 URL 列表，用於圖生圖或圖像編輯⚠️ 僅支持 URL 格式（不再支持 base64）

公開可訪問的圖像 URL（http:// 或 https://）
示例：https://example.com/image.jpg
可使用上傳圖片接口上傳本地圖片獲取 URL

限制：

最多 10 張圖片
圖像格式：jpeg, png
寬高比（寬/高）範圍：[1/3, 3]
寬度和高度（px）> 14
單張圖片大小：不超過 10MB
總像素：不超過 6000×6000 px

object

渠道特有參數，用於傳遞 Seedream 4.0 模型的高級配置

顯示 metadata 屬性

string

預設值:"2K"

圖像分辨率支持的分辨率：

1K - 基礎分辨率
2K - 標準分辨率（默認）
4K - 高清分辨率

分辨率參考尺寸：

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

object

提示詞優化選項屬性：

mode（字符串）：優化模式
- standard：標準模式，生成質量更高，處理時間更長（默認）
- fast：快速模式，處理時間更短，質量一般

示例：

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

string

預設值:"disabled"

順序圖像生成模式（豆包專屬功能）控制是否生成多張圖像：

disabled：禁用順序模式，即使有多張參考圖像也只生成 1 張（默認）
auto：啓用順序模式，可以生成多張圖像

使用說明：

✅ 設置 n: 3 或使用 sequential_image_generation: "auto" + max_images: 3
✅ 支持文生圖：僅提供文本提示詞，最多生成 15 張圖像
✅ 支持圖生圖：提供 image_urls，基於參考圖像生成多張圖像
⚠️ 當 n > 1 時，會自動設置爲 auto

注意：

輸入的參考圖數量 + 最終生成圖片數量 ≤ 15 張

object

順序圖像生成選項當 sequential_image_generation 設置爲 auto 時可用屬性：

max_images（整數）：指定生成的圖像數量，範圍：1-15

示例：

"sequential_image_generation_options": { "max_images": 3 }

boolean

預設值:true

是否爲生成的圖像添加水印

true：添加水印（默認）
false：不添加水印

queued - 排隊等待處理
in_progress - 處理中
completed - 成功完成
failed - 失敗

integer

任務進度百分比（0-100）

integer

任務創建時間戳（Unix 時間戳）

object
