Prerequisites

To get started with Stable Diffusion 3.5 Large, you will need a Cognitive Actions API key and a basic understanding of making API calls. This will enable you to integrate the image generation capabilities into your applications effortlessly.

Generate Image with Stable Diffusion

The "Generate Image with Stable Diffusion" action is designed to create custom images based on textual prompts. By leveraging configurable parameters such as guidance scale, the number of denoising steps, and image dimensions, developers can fine-tune the output to achieve the desired quality and style.

Input Requirements

To use this action, you will need to provide the following input parameters:

  • Prompt: A textual description of the desired image (e.g., "A man with hoodie on, illustration").
  • Width: The width of the output image in pixels (default is 1024, range is 1 to 2048).
  • Height: The height of the output image in pixels (default is 1024, range is 1 to 2048).
  • Steps: The number of denoising steps to refine the image (default is 28, must be between 1 and 50).
  • Guidance Scale: A scale factor for classifier-free guidance, affecting the output style (default is 4.5, range is 0 to 20).
  • Negative Prompt: Optional text to specify elements to exclude from the generated content, helping to refine the output.
  • Number of Images: The number of images to generate (default is 1, can be between 1 and 4).

Expected Output

The output will be a link to the generated image, which will meet the specifications provided in the input. For example, a successful call might return an image link similar to:
