You cannot start generating AI images more easily than with Fooocus software. The installation and running is fully automatic. It needs a mediocre GPU (I use GTX 1660 Ti 6GB Turing) and generation (fully local, on my GPU, no internet and no censorship) of a 1024x1024 image takes only 1 to 3 minutes (just seconds on better RTX cards).
Everyone should just start with Fooocus (weighs 20GB with 2 built-in models) and, when you learn the basics, use other GUIs like ComfyUI and other models like dreamshaperXL_v2Turbo (free at civitai.com, weighs only 6GB).
