Task Submission Parameters
Request Parameters
| Parameter | Type | Required | Default | Range | Description |
|---|---|---|---|---|---|
| prompt | string | Yes | - | The prompt to generate an image from. | |
| size | string | No | 1024*1024 | 512 ~ 2048 per dimension | The size of the generated image. |
| guidance_scale | number | No | 2.5 | 0.0 ~ 20.0 | The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you. |
| seed | integer | No | -1 | -1 ~ 2147483647 | The same seed and the same prompt given to the same version of the model will output the same image every time. |
| enable_base64_output | boolean | No | false | - | If enabled, the output will be encoded into a BASE64 string instead of a URL. |
| enable_sync_mode | boolean | No | false | - | If set to true, the function will wait for the image to be generated and uploaded before returning the response. It allows you to get the image directly in the response. This property is only available through the API. |
