Not sure what “your own” in the title is supposed to mean if you are running a model that you didn’t train using a framework that you didn’t write on a server that you don’t own.
Which involves taking some rolling papers, a pouch of loose tobacco (or whatever), and perhaps a little device if you're rich. As opposed to manufactured cigarettes, you're just doing some manual assembly for the end-product.
You don't need to cultivate the plants or pulp any trees to roll your own.
