15 properties · 1 required · 3 $defs

property	type	description	constraints
prompt*	string	The prompt to use for generating the image. Be as descriptive as possible for best results.
image_size	ImageSize \| enum		default: {"height":1024,"width":1024}
guidance_scale	number	The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you.	0 ≤ n ≤ 20 · default: 5
enable_safety_checker	boolean	If set to true, the safety checker will be enabled.	default: true
request_id	string	An id bound to a request, can be used with response to identify the request itself.	default: ""
loras	LoraWeight[]	The list of LoRA weights to use.	default: []
num_images	integer	The number of images to generate.	1 ≤ n ≤ 8 · default: 1
num_inference_steps	integer	The number of inference steps to perform.	1 ≤ n ≤ 70 · default: 35
negative_prompt	string	The negative prompt to use. Use it to address details that you don't want in the image.	default: "(worst quality, low quality, no…
embeddings	Embedding[]	The list of embeddings to use.	default: []
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
format	enum	The format of the generated image.	jpeg \| png · default: "jpeg"
expand_prompt	boolean	If set to true, the prompt will be expanded with additional prompts.	default: false
safety_checker_version	enum	The version of the safety checker to use. v1 is the default CompVis safety checker. v2 uses a custom ViT model.	v1 \| v2 · default: "v1"
seed	integer	The same seed and the same prompt given to the same version of Stable Diffusion will output the same image every time.	nullable

Types

3 $defs

Embeddingobject

path*	string	URL or the path to the embedding weights.
tokens	string[]	The list of tokens to use for the embedding. When omitted, tokens are generated as <s0>, <s1>, ... to match the number of vectors in the embedding file.	nullable

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

force	boolean	If set to true, the embedding will be forced to be used.	default: false
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 ≤ 1 · default: 1
path*	string	URL or path to a LoRA safetensors file. Or HF model name that resolves to safetensors weights.
