Speaking of the UI for "Stable Diffusion," "WebUI1111" is well-known. However, "Stable Diffusion," and similar programs, are written in Python, which makes the operating speed somewhat slow. Therefore, "StableDiffusion.cpp" was created by rewriting the source code in C++ to make it faster. Furthermore, "Sd Portal," which I will introduce this time, makes it usable with a UI. ・Advantages of StableDiffusion.cpp 　・Fast operating speed (works even without a GPU) 　・No authentication required at startup (can be used without an internet connection) 　・No need to install Python. ・Advantages of SdPortal 　・It's a UI, so you don't have to type into the console.
