Request body

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.
enable_safety_checker	boolean	If set to true, the safety checker will be enabled.	default: true
embeddings	Embedding[]	The list of embeddings to use.	default: []
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"
image_size	ImageSize \| enum		default: {"width":1024,"height":1024}
loras	LoraWeight[]	The list of LoRA weights to use.	default: []
num_images	integer	The number of images to generate.	1 ≤ n ≤ 8 · default: 1
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"
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
num_inference_steps	integer	The number of inference steps to perform.	1 ≤ n ≤ 70 · default: 35
request_id	string	An id bound to a request, can be used with response to identify the request itself.	default: ""
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…
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

width	integer	The width of the generated image.	0 < n ≤ 14142 · default: 512
height	integer	The height 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
path*	string	URL or path to a LoRA safetensors file. Or HF model name that resolves to safetensors weights.
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
