About This Workflow

Overview

This workflow leverages the OpenAI API to generate images. It allows users to specify prompts, the number of images, size, quality, and model. The generated images, initially returned as base64 data, are then converted to a file format for further processing or download.

Key Features

Supports customizable prompts, image count, size, and quality.
Converts base64 image data to a binary file.
Includes placeholder for credential management.
Uses environment variables for API base URL.

Update Environment Variables: Set API_BASE_URL to your OpenAI API endpoint (e.g., https://api.openai.com/v1/images/generations).
Adjust Node Parameters: Modify the Set Variables node to change the image_prompt, number_of_images, size_of_image, quality_of_image, and openai_image_model as needed.
