The 'Nano Banana Pro: AI Image Enhancement' workflow is designed to upscale and enhance AI-generated images, transforming them into high-resolution 4K outputs with improved sharpness and coherence. This workflow leverages the power of the Nano Banana Pro model, known for its exceptional ability to refine image details and enhance visual quality. The process begins with the LoadImage node, which allows users to upload their AI-generated images into the system. The core of the enhancement process is handled by the GeminiImage2Node, which applies sophisticated algorithms to upscale and enhance the image. Finally, the SaveImage node ensures that the enhanced image is saved in the desired format and location.
