| `prompt`          | string  | yes      | -        | Text prompt. With image attached, becomes an editing instruction. For batch mode, describe each image sequentially.                                                                                        |
| `aspect_ratio`    | enum    | no       | `"auto"` | Auto lets the model choose dimensions within the selected resolution tier. Explicit ratios use the preset size for that tier. · Allowed: `auto`, `1:1`, `16:9`, `9:16`, `4:3`, `3:4`, `3:2`, `2:3`, `21:9` |
| `quality`         | enum    | no       | `"2K"`   | 2K is about 4MP. 3K is about 9MP. · Allowed: `2K`, `3K`                                                                                                                                                    |
| `use_custom_size` | boolean | no       | false    | Use custom_width and custom_height instead of preset aspect_ratio and quality. Applies when aspect_ratio is auto.                                                                                          |

| `image`           | array   | no       | -        | Up to 14 reference image URLs for editing. Triggers image-edit mode.                                                                                                                                       |
| `images`          | array   | no       | -        | Alias for image. Use this for multiple uploaded image references.                                                                                                                                          |
| `batch_enabled`   | boolean | no       | false    | Generate a cohesive set of related images from a single prompt. A max_images above 1 also generates a set.                                                                                                 |
| `max_images`      | number  | no       | `4`      | Batch mode only. Maximum images in the set; the model decides actual count. You are billed only for images returned. · Range: 1 – 15                                                                       |
| `watermark`       | boolean | no       | false    | When enabled, the generated image includes an AI-generated provenance watermark. EmpirioLabs does not add a separate watermark.                                                                            |

## Notes

Multi-image reference combine and edit. Stronger reasoning before rendering than 4.0. Per generated image is billed; batch mode bills per actual image returned.

**Content safety**

* Generated images pass an automated content-safety check. An image flagged as explicit is not returned. Because the image is generated before the check runs, a flagged generation is still billed.
