Text-to-Image Parameters

prompt [str]: The text prompt describing the content, style, or composition of the image to be generated.
num_images [int]: The number of images to generate
seed [int]: The random seed for image generation
aspect_ratio [ 21:9, 16:9, 4:3, 3:2, 1:1, 2:3, 3:4, 9:16, 9:21 ]: The aspect ratio for the image
guidance_scale [1-20]: 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.
safety_tolerance [1-6]: The safety tolerance level for the generated image. 1 being the most strict and 5 being the most permissive.

Use cases

Professional branding, advertising, and editorial visual design
Content creators requiring superior prompt control and rapid, precise edits
