Build - Stable Diffusion XL
Stable Diffusion XL is the latest version of the painting model released by Stability AI. You only need to describe it in words, and you can let the computer help you draw. In general, you need to configure your own computing power (such as a high-performance graphics card), but NVIDIA provides an online, free Stable Diffusion XL service that is ready to use.
This is a free instance hosted on NVIDIA NGC (NVIDIA GPU Cloud, a GPU-accelerated cloud platform optimized for deep learning and scientific computing).
