| 参数 | 位置 | 类型 | 必填 | 说明 | 示例 |
|---|---|---|---|---|---|
Authorization | Header | string | 否 | - | Bearer {{YOUR_API_KEY}} |
input | JSON body | object | 否 | - | - |
input.prompt | JSON body | string | 是 | 您想要生成的内容的文本描述，或有关如何编辑给定图像的说明。 | - |
input.go_fast | JSON body | boolean | 否 | 使模型运行速度更快，对于更困难的提示，输出质量可能会略有下降。默认值：true。 | - |
input.guidance | JSON body | number | 否 | 提示词引导强度。默认值: 2.5。最小值：0，最大值：10 | - |
input.input_image | JSON body | string | 是 | 用作参考的图片。必须是 jpeg、png、gif 或 webp 格式。 | - |
input.aspect_ratio | JSON body | string | 否 | 生成图像的长宽比。使用“match_input_image”来匹配输入图像的长宽比。默认值：“match_input_image”。 | - |
input.output_format | JSON body | string | 否 | 输出图像格式。默认值：“webp”。 | - |
input.output_quality | JSON body | integer | 否 | 保存输出图像时的质量，范围为 0 至 100。100 为最佳质量，0 为最低质量。与 .png 输出无关。默认值：80。最小值：0，最大值：100。 | - |
input.num_inference_steps | JSON body | integer | 否 | 推理步骤数，默认值：28。最小值：4，最大值：50。 | - |
