Request body
11 properties · 1 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| prompt* | string | The prompt to generate a ballpoint pen sketch style image. Use 'b4llp01nt' trigger word for best results. | |
| image_size | ImageSize | enum | The size of the generated image. | default: "landscape_4_3" |
| output_format | enum | The format of the output image | png | jpeg | webp · default: "png" |
| num_inference_steps | integer | The number of inference steps to perform. | 4 ≤ n ≤ 50 · default: 40 |
| enable_safety_checker | boolean | Whether to enable the safety checker for the generated image. Disabling it requires account authorization; unauthorized requests are always checked. | default: true |
| seed | integer | Random seed for reproducibility. Same seed with same prompt will produce same result. | nullable |
| guidance_scale | number | The CFG (Classifier Free Guidance) scale. Controls how closely the model follows the prompt. | 0 ≤ n ≤ 20 · default: 2.5 |
| sync_mode | boolean | If `True`, the media will be returned as a data URI and won't be saved in history. | default: false |
| lora_scale | number | The strength of the ballpoint pen sketch effect. | 0 ≤ n ≤ 2 · default: 1 |
| acceleration | enum | Acceleration level for image generation. 'regular' balances speed and quality. | none | regular · default: "regular" |
| num_images | integer | Number of images to generate | 1 ≤ n ≤ 4 · default: 1 |
Types
1 $defsImageSizeobject
| height | integer | The height of the generated image. | 0 < n ≤ 14142 · default: 512 |
| width | integer | The width of the generated image. | 0 < n ≤ 14142 · default: 512 |
