Request body

9 properties · 2 required · 1 $defs

property	type	description	constraints
prompt*	string	The text prompt used to edit the image
image_urls*	string[]	List of URLs of input images for editing. Presently, up to 10 image inputs are allowed. If over 10 images are sent, only the last 10 will be used.
num_images	integer	Number of separate model generations to be run with the prompt.	1 ≤ n ≤ 6 · default: 1
image_size	ImageSize \| enum	The size of the generated image. The minimum total image area is 921600 pixels. Failing this, the image size will be adjusted to by scaling it up, while maintaining the aspect ratio.	default: {"height":2048,"width":2048}
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
enable_safety_checker	boolean	If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked.	default: true
seed	integer	Random seed to control the stochasticity of image generation.	nullable
enhance_prompt_mode	enum	The mode to use for enhancing prompt enhancement. Standard mode provides higher quality results but takes longer to generate. Fast mode provides average quality results but takes less time to generate.	standard \| fast · default: "standard"
max_images	integer	If set to a number greater than one, enables multi-image generation. The model will potentially return up to `max_images` images every generation, and in total, `num_images` generations will be carried out. In total, the number of images generated will be betw…	1 ≤ n ≤ 6 · default: 1
