图像编辑

接口概述

基于输入图片和编辑指令，实现图像编辑能力：支持修改图中文字、增删或移动物体、改变主体动作、迁移图片风格、多图融合。采用 DashScope 多模态生成协议，请求体为 input + parameters 嵌套结构。

按张计费（输出 n 张即 n 倍单价），本次费用可在控制台「费用中心」查看。

简写形式（可选）

除嵌套体之外，也可以把常用字段直接放在顶层，接口会按上表结构处理，两种写法等价、选一种即可：

模型差异

分辨率说明

适用于支持自定义分辨率的模型（qwen-image-edit-plus / qwen-image-edit-max）：

• 宽和高的取值范围均为 [512, 2048] 像素；
• 默认接近 1024*1024，宽高比与输入图相近；
• 指定 size 时会调整为最接近的 16 的倍数；
• 输出图像格式为 PNG。

推荐分辨率：

请求示例

单图编辑：

{
  "model": "qwen-image-edit-plus",
  "input": {
    "messages": [{
      "role": "user",
      "content": [
        {"image": "https://example.com/photo.jpg"},

      ]
    }]
  }
}

多图融合：

响应示例

编辑成功（单图）：

{
  "output": {
    "choices": [{
      "finish_reason": "stop",
      "message": {
        "role": "assistant",
        "content": [{"image": "https://example.com/edited.png"}]
      }
    }]
  },

  "size": "1024*1024",
  "request_id": "a1b2c3d4-e5f6-7890-abcd-1234567890ab"
}

多图输出：

  "output": {
    "choices": [{
      "finish_reason": "stop",
      "message": {
        "role": "assistant",
        "content": [
          {"image": "https://example.com/edited-1.png"},
          {"image": "https://example.com/edited-2.png"}
        ]
      }
    }]

  "size": "1024*1024",
  "request_id": "b2c3d4e5-f6a7-8901-bcde-1234567890ac"
}

错误响应

参数校验不通过时返回参数错误；模型侧报错时接口以 502 返回，detail 里带上模型给出的原始错误正文，便于对照定位。完整状态码与排查建议见「错误码」页。

参数校验错误：

{
  "error": {
    "message": "model is required",
    "type": "invalid_request_error",
    "code": "invalid_request_error"
  }
}

模型服务返回的错误（形态随模型侧实现而异，常见两种）：

{
  "error": {
    "message": "Invalid API-key provided.",
    "type": "invalid_request_error",
    "code": "InvalidApiKey"
  }
}

{
  "request_id": "31f808fd-8eef-9004-xxxxx",
  "code": "InvalidApiKey",
  "message": "Invalid API-key provided."
}

调用失败记 0 费用，但仍会在控制台留一条失败记录。
