Sora The Reaper

Stable Diffusion XL 0.9 (the version I've used), is hands down one of the best programs I've used. It however, if you don't get free credits, depressingly enough, you have to pay for more to be able to use it.

If you want to use MidJourney on Discord, you have to pay for it. They don't allow a "free trial" anymore. So, if you don't want to shell out cash, you need to look elsewhere.
