Too expensive from what I have seen - price for reasonably large GPU rigs that can host medium to large models is anywhere between ~5$/hr to ~9$/hr. That's ~40$-72$ for 8-hour working day or ~800$-1500$ for ~20 working days in a month. That's ~1000$ a month in average. This doesn't math for me.

I was assuming hobbyist use, so on the order of 2-4 hours every couple days
