I use it quite a bit. I don’t trust big companies who commercialize AI so I run my AIs locally on my old retired gaming desktop that I’ve turned into a homelab/media server.
I use Kobold.AI to self host an LLM like ChatGPT (Dolphin-Mistral7b if you are curious). I mainly use it for low effort knowledge searches for stuff that is easier typed out long and descriptive (since google struggles with this). Since it’s AI I have to be careful about what I search since I’ve seen it make stuff up but for the majority of what I use it for (Programming syntax, Linux troubleshooting, general questions) it’s pretty good.
I also have Stable Diffusion running as well using the ICBINP model (which is pretty decent for photorealistic images). I use this AI to generate social media display pictures and porn :) it’s fun because it’s a surprise at what you’re going to get but sometimes it generates absolute horrors. Anatomical horrors. Those are genuinely horrific. Other times it’s really good.
