Generate and edit images using NVIDIA FLUX models. Use when user asks to generate images, create pictures, edit photos, or modify existing images with AI. Supports text-to-image generation and image editing with text prompts.Key capabilities
- →Edit existing images using text instructions
- →Specify output image width and height
- →Set aspect ratios for generated images
- →Control image generation reproducibility with a seed
How it works
This skill uses NVIDIA FLUX models to generate images from text prompts or edit existing images based on text instructions. It allows specifying parameters like dimensions, aspect ratio, and a random seed.
