1. I use Stable Diffusion 1.5 with Automatic1111 1.6 on a Windows machine.
2. You need a pretty powerful/modern GPU, typically a NVIDIA 3000/4000 series
3. I have no idea if you can do this on a Mac.
4. Apparently you can run that in Google Cloud. I've never tried it. Id guess its either slow, expensive or both
5. I'm not inclined to start publishing lessons on how-to. For a number of reasons, principally I'm time poor, and not really that good at teaching.
6. You can learn more about how to get started with Stable Diffusion on reddit and there's a few good pages that your search engine of choice will return.
7. While these pics are good, they're not perfect. I discard way more than I post here, something to keep in mind if you go down this road. Be prepared for so many wayyyy weird results.
Peace out. PD.
[EDIT] Ok ok i've had a few people ask me if I can put together some of the wild misses that the AI sometimes throws up. I'll do that soon, I've got to remember to keep them first (I usually just delete them and move on)
[EDIT EDIT] I put a "Frankengen" post on my main blog @pandorasdaddy - be warned, it's nightmare fuel
