8 properties · 1 required · 1 $defs

property	type	description	constraints
prompt*	string	The text prompt used to generate the image
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. Total pixels must be between 960x960 and 4096x4096.	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
