GPT Image API 客户端
|
||
支持两个接口：
|
||
- POST /v1/images/generations/ 文生图 / 图生图（gpt-image-1 / gpt-image-1.5）
|
||
- POST /v1/images/edits/ 图像编辑（带蒙版 inpainting）
|
||
|
||
设计原则：
|
||
- 与 doubao_image_client.py 保持相同的异步 + 同步双入口模式
|
||
- 图像以 multipart/form-data 方式上传（edits 接口）
|
||
- generations 接口使用 JSON 请求体，图像以 data URI base64 内联传递
|
||
- 响应支持 url 和 b64_json 两种格式，优先处理 b64_json（避免二次下载）
