Seedream 5.0 Pro 高質量圖像生成模型，由字節跳動 Seed 團隊研發
通過 model 參數選擇 doubao-seedream-5-0-pro 模型
參數與 Seedream-5.0 基本一致，差異在於 Pro 支持 1K 和 2K 分辨率
支持文生圖、圖生圖、多圖參考等生成模式
計費規則：首張參考圖免費，從第 2 張參考圖開始按正常規則計費
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。

Body

model

string

預設值:"doubao-seedream-5-0-pro"

必填

圖像生成模型名稱示例："doubao-seedream-5-0-pro"

prompt

string

必填

圖像生成的文本描述

size

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

integer

預設值:1

生成圖像的數量範圍：1-10（最少 1 張，最多 10 張）默認：1注意：

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

會根據生成數量和參考圖數量進行預扣費，其中首張參考圖免費

image_urls

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://）
可使用上傳圖片接口上傳本地圖片獲取 URL

限制：

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

計費說明：

首張參考圖免費
從第 2 張參考圖開始按正常規則計費

metadata

object

渠道特有參數，用於傳遞 Seedream 5.0 Pro 模型的高級配置

顯示 metadata 屬性

metadata.resolution

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）

注意： Seedream 5.0 Pro 不支持 3K 和 4K 分辨率；非 Pro 的 Seedream 5.0 支持 2K 和 3K

metadata.sequential_image_generation

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
✅ 支持文生組圖：僅提供文本提示詞，最多生成 10 張圖像
✅ 支持圖生圖/圖生組圖：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

metadata.sequential_image_generation_options

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：1-10

示例：

"sequential_image_generation_options": { "max_images": 3 }

metadata.watermark

boolean

預設值:false

是否爲生成的圖像添加水印

true：添加水印
false：不添加水印（默認）
