Parameters

Input
Output

prompt

stringrequiredminLength: 1A text description of the image you want to generate.

guidance

numberdefault: 4.5minimum: 0maximum: 10Controls how closely the generated image should adhere to the prompt; higher values make the image more aligned with the prompt

seed

integerminimum: 0Random seed for reproducibility of the image generation

height

integerdefault: 1120minimum: 0maximum: 2500The height of the generated image in pixels

width

integerdefault: 1120minimum: 0maximum: 2500The width of the generated image in pixels

num_steps

integerminimum: 1maximum: 40The number of diffusion steps; higher values can improve quality but take longer
