OpenAI API 支持上传标注图像指定编辑区域，并可按复杂度与画质分级

You can now send a marked-up image to the API to show exactly where you want an edit. For most edits, start with low complexity. If a scene has several elements or constraints to juggle, try medium or high to give the model more room to plan. Set image quality separately for the level of detail you need.
