Prerequisites

To get started with Flux Schnell, you'll need a valid Cognitive Actions API key and a basic understanding of how to make API calls.

Generate Image with FLUX Schnell

The Generate Image with FLUX Schnell action is designed to create new images from text prompts (Text2Img) or modify existing images (Img2Img). This action solves the challenge of high-quality image generation with customizable parameters, including output dimensions, format, and quality.

Input Requirements

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

  • Prompt: A descriptive text guiding the content of the generated image (e.g., "black forest gateau cake spelling out the words 'FLUX SCHNELL'").
  • Width: The desired width of the output image in pixels (default is 1024).
  • Height: The desired height of the output image in pixels (default is 1024).
  • Image: An input image URI for image modification (Img2Img mode).
  • Strength: A value from 0 to 1 controlling the denoising strength for image-to-image mode.
  • Output Format: The format of the output image (choices include webp, jpg, or png).
  • Output Quality: The quality level for saving output images, ranging from 0 (lowest) to 100 (highest).
  • Number of Outputs: The total number of images to generate (between 1 and 4).
  • Number of Inference Steps: The number of inference steps for image generation (from 1 to 12).

Expected Output

The expected output will be a URL link to the generated image, which you can use directly in your applications. For example, the output could look like this:

  • https://assets.cognitiveactions.com/invocations/0fc4d94a-aacc-426a-a376-55f26aa221f2/8038ccb8-8fe8-4aeb-8811-7f4f00ee0a73.png
