Parameters

* indicates a required field

Input

  • prompt string required min 1

    A text description of the image you want to generate.

  • guidance number default 4.5 min 0 max 10

    Controls how closely the generated image should adhere to the prompt; higher values make the image more aligned with the prompt

  • seed integer min 0

    Random seed for reproducibility of the image generation

  • height integer default 1120 min 0 max 2500

    The height of the generated image in pixels

  • width integer default 1120 min 0 max 2500

    The width of the generated image in pixels

  • num_steps integer default 4 min 1 max 40

    The number of diffusion steps; higher values can improve quality but take longer

Output

  • image string

    The generated image in Base64 format.
