💡CFG Scale

CFG Scale refers to the 'Coarse-to-Fine Generation' scale in the context of Stable Diffusion, a type of AI model used for image generation. It is a method where the AI starts with a rough, low-resolution image and gradually refines it to a higher resolution. This process is used to create more detailed and realistic images by adding layers of complexity. In the video, CFG Scale is likely discussed as a technique to enhance the quality of images generated by the Stable Diffusion model.

💡Stable Diffusion

Stable Diffusion is an AI-based model that specializes in generating high-quality images from textual descriptions.
