Prerequisites

To use the Flux1 Schnell Multi LoRA service, you will need a valid Cognitive Actions API key and a basic understanding of making API calls.

Generate Image with Multi-LoRA Support

The Generate Image with Multi-LoRA Support action allows you to create images with intricate details and styles by harnessing the power of multiple LoRA models. This action addresses the challenge of producing visually appealing images that meet specific criteria, ensuring a high degree of customization.

Input Requirements

  • Prompt: A text description that guides the image generation process.
  • Seed: An optional integer to generate reproducible outputs.
  • Image: (for image-to-image mode) A URI for an input image to maintain aspect ratio.
  • Image Format: Choose from webp, jpg, or png for the output image.
  • Image Quality: Define the quality of the output image on a scale from 0 to 100.
  • Number of Outputs: Specify how many images to generate (1 to 4).
  • Huggingface Loras: A list of URLs to LoRA weights for enhanced image generation.
  • Image Aspect Ratio: Specify the desired aspect ratio (e.g., 16:9, 4:3).
  • LoRA Weight Scales: Define the scale for LoRA weights for customization.
  • Image Prompt Strength: Set the strength of the text prompt.
  • Safety Checker Disabled: Option to disable the safety checker if needed.
  • Number of Inference Steps: Control the number of inference steps (1 to 4).

Expected Output

The expected output is a URL to the generated image, which can be used directly in applications or displayed on websites.

Use Cases for this specific action:

  • Creative Projects: Ideal for artists and designers looking to generate unique visuals based on descriptive prompts.
  • Game Development: Generate character designs or landscapes quickly to prototype game ideas.
  • Marketing Campaigns: Create customized promotional images that align with brand messaging.
  • Social Media Content: Produce eye-catching images for posts and advertisements.
