Parameters

Parameter	Type	Required	Default	Description
`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.
`custom_width`	number	no	-	Pixels. Total area must be in [2.56MP, 10.4MP]; aspect must be in [1:16, 16:1]. Only when use_custom_size=true. · Range: 1024 – 4704
`custom_height`	number	no	-	Pixels. Total area must be in [2.56MP, 10.4MP]; aspect must be in [1:16, 16:1]. Only when use_custom_size=true. · Range: 1024 – 4704
`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.
`max_images`	number	no	`4`	Batch mode only. Maximum images in the set; the model decides actual count. You’re 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.
`output_format`	enum	no	`"png"`	Output image file format. · Allowed: `jpeg`, `png`
`response_format`	enum	no	`"url"`	Return signed image URLs by default, or include base64 image data when b64_json is requested. · Allowed: `url`, `b64_json`

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.
