Keywords

💡Stable Diffusion XL

Stable Diffusion XL is a new version of a text-to-image AI system that has been updated to produce higher resolution images and handle more complex concepts. It is significant in the video as it represents the main subject being discussed. The term is used to describe the advancements in AI technology that allow for more detailed and accurate image generation from textual descriptions.

💡Text-to-Image AI

Text-to-Image AI refers to artificial intelligence systems that can create images from textual descriptions. In the context of the video, it is the technology that underpins Stable Diffusion XL, allowing it to generate images based on the text provided by users.
