Keywords

💡Stable Diffusion

Stable Diffusion is a term used in the context of AI-generated imagery. It refers to a model that creates realistic images by learning from a vast dataset of images. In the video, Stable Diffusion is the primary tool used to generate images that closely resemble real-life scenarios, as the user aims to explain the process of using this technology to create high-quality images.

💡Checkpoint

A checkpoint in the context of the video refers to a specific point in the AI model's training process where the model's performance is saved. This saved state, or checkpoint, can then be used to continue training or to generate images without having to start from scratch. In the video, the checkpoint is a crucial component that provides the overall structure or 'shape' of the images to be generated.

💡Lora

Lora is mentioned as a component in the video that deals with the detailed parts of the image generation process, analogous to 'trees' in the mountain and tree analogy used in the script. It is a model that focuses on specific aspects of the image, such as facial features or hands, providing detailed work that brings the image to life.
