使用此路由可通过 CometAPI 以兼容 OpenAI 的请求格式从文本创建图像。

​
官方参考

​
先选择模型

  • 当你想用 response_format 发起一个简单的首次请求时，使用 dall-e-3
  • 当你需要仅适用于 GPT 的控制项（如 output_format、quality 或 background）时，使用 GPT 图像模型
  • 当你明确需要该提供商时，使用 qwen-image，但请将 n 保持为 1

​
安全的首次请求

  • 从 dall-e-3 开始
  • 将 size 保持为 1024x1024
  • 如果你希望获得较小的 JSON 响应以及一个临时下载 URL，请设置 response_format: "url"
  • 如果你需要 GPT 图像模型参数，请使用 API 参考中已验证的 GPT 请求示例
  • 仅当你需要特定编码图像类型（如 jpeg）时，再添加 output_format
  • 在添加 background、output_compression 或流式输出之前，请先查看 OpenAI 图像生成指南
  • 在添加批量生成或风格调优之前，先使用一个 Prompt 和一张输出图像

​
特定模型的请求行为

  • response_format 适用于 dall-e-2 和 dall-e-3
  • GPT 图像模型使用仅适用于 GPT 的控制项，例如 output_format、quality、background 和 output_compression
  • 请遵循 OpenAI 图像生成指南以了解最新的特定模型选项
  • qwen-image 不支持 n > 1
生成的图像必须遵守提供商的使用政策。请勿发送违法、暴力、色情或侵犯版权的 Prompt。

授权

​
Authorization
string
header
必填

Bearer token authentication. Use your CometAPI key.

请求体

application/json
​
model
string
默认值:dall-e-3
必填

The image generation model to use. Choose a current model from the Models page.

​
prompt
string
必填

Text description of the image you want to generate.

示例:

"A paper boat floating on calm water at sunrise."

​
n
integer
默认值:1

Number of images to generate. Keep this at 1 for the broadest compatibility.

​
quality
string

Quality setting for models that support it. See the OpenAI image generation guide for the latest model-specific values.

​
size
string

Requested output size. Supported values depend on the selected model. See the OpenAI image generation guide for the latest model-specific ranges.

示例:

"1024x1024"

​
response_format
enum<string>

The response container for dall-e-2 and dall-e-3. This parameter is not supported for GPT image models, which return base64-encoded image data.

可用选项:
url,
b64_json
​
output_format
string

The encoded image type for GPT image model results, such as png, jpeg, or webp. See the OpenAI image generation guide for current GPT image output controls.

示例:

"jpeg"

响应

200 - application/json

Image generation result.

​
created
integer
必填

Unix timestamp for the completed generation.

​
usage
object
必填
​
data
object[]
必填
​
background
string

Background mode returned by models that expose it.

​
output_format
string

Encoded image type returned by GPT image models.

​
quality
string

Quality level returned by models that expose it.

​
size
string

Output size returned by models that expose it.
