Request body

15 properties · 1 required · 2 $defs

property	type	description	constraints
prompt*	string	The text prompt to guide image generation.
enable_prompt_expansion	boolean	Whether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning.	default: false
enable_safety_checker	boolean	If set to true, input data will be checked for safety before processing. Disabling it requires account authorization; unauthorized requests are always checked.	default: false
reverse_video	boolean	If true, the video will be reversed.	default: false
negative_prompt	string	Negative prompt for video generation.	default: ""
acceleration	enum	Acceleration level to use. The more acceleration, the faster the generation, but with lower quality. The recommended value is 'regular'.	none \| regular · default: "regular"
shift	number	Shift value for the image. Must be between 1.0 and 10.0.	1 ≤ n ≤ 10 · default: 2
image_size	ImageSize \| enum	The size of the generated image.	default: "square_hd"
enable_output_safety_checker	boolean	If set to true, output video will be checked for safety after generation.	default: false
num_inference_steps	integer	Number of inference steps for sampling. Higher values give better quality but take longer.	2 ≤ n ≤ 40 · default: 27
loras	LoRAWeight[]	LoRA weights to be used in the inference.	default: []
seed	integer	Random seed for reproducibility. If None, a random seed is chosen.	nullable
guidance_scale_2	number	Guidance scale for the second stage of the model. This is used to control the adherence to the prompt in the second stage of the model.	1 ≤ n ≤ 10 · default: 4
image_format	enum	The format of the output image.	png \| jpeg · default: "jpeg"
guidance_scale	number	Classifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality.	1 ≤ n ≤ 10 · default: 3.5

Types

2 $defs

ImageSizeobject

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

LoRAWeightobject

scale	number	The scale of the LoRA weight. This is used to scale the LoRA weight before merging it with the base model.	0 ≤ n ≤ 4 · default: 1
path*	string	URL or the path to the LoRA weights.
transformer	enum	Specifies the transformer to load the lora weight into. 'high' loads into the high-noise transformer, 'low' loads it into the low-noise transformer, while 'both' loads the LoRA into both transformers.	high \| low \| both · default: "high"
weight_name	string	Name of the LoRA weight. Used only if `path` is a Hugging Face repository, and required only if you have more than 1 safetensors file in the repo.	nullable
