Request body
12 properties · 2 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| image_url* | string | The URL of the image to edit. | |
| prompt* | string | The prompt to edit the image. | |
| output_format | enum | The format of the generated image. | jpeg | png · default: "png" |
| guidance_scale | number | 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. | 0 ≤ n ≤ 20 · default: 2.5 |
| acceleration | enum | The speed of the generation. The higher the speed, the faster the generation. | none | regular | high · default: "none" |
| sync_mode | boolean | If `True`, the media will be returned as a data URI and the output data won't be available in the request history. | default: false |
| num_inference_steps | integer | The number of inference steps to perform. | 10 ≤ n ≤ 50 · default: 30 |
| seed | integer | The same seed and the same prompt given to the same version of the model will output the same image every time. | nullable |
| num_images | integer | The number of images to generate. | 1 ≤ n ≤ 4 · default: 1 |
| resolution_mode | enum | Determines how the output resolution is set for image editing. - `auto`: The model selects an optimal resolution from a predefined set that best matches the input image's aspect ratio. This is the recommended setting for most use cases as it's what the model w… | auto | match_input | 1:1 | 16:9 | 21:9 | 3:2 · +7 more · default: "match_input" |
| enable_safety_checker | boolean | If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked, and images flagged as unsafe are returned as black images. | default: true |
| loras | LoraWeight[] | The LoRAs to use for the image generation. You can use any number of LoRAs and they will be merged together to generate the final image. | default: [] |
Types
1 $defsLoraWeightobject
| scale | number | The scale of the LoRA weight. This is used to scale the LoRA weight before merging it with the base model. | 0 ≤ n ≤ 4 · default: 1 |
| path* | string | URL or the path to the LoRA weights. |
