I would skip all the tech talk and go to the practical, artist-friendly systems first of all.

This would for instance be the Krita plugin and InvokeAI. Both heavily cater to an user with little interest of getting into the weeds of VAEs and UNet models, and is much more at home using a drawing tablet.

Krita is closer to being artist-targeted since it's primarily a drawing application with an AI add-on.

InvokeAI is more on the opposite side, an AI tool with primitive but still usable ability to guide the AI by sketching stuff on a canvas.
