I've set it up on my local machine just now, as my first local image diffuser. I can confirm it's very easy.

I tried stable-diffusion.cpp, following its compile guide here[0], and its Qwen Image-2.1 specific instructions here[1]. It works out of the box. I made a test pelican[2]. It took 3 minutes on a CPU.
