Newie wondering what models I can run

I recently installed text-generation-webui and I'm trying to find some models to mess about with, so far I've gotten TinyLlama and GPT2 to work but no others.
I have an NVIDIA GeForce GTX 1660 SUPER with 6GB of RAM, I was really hoping to get dreamgen working but that seems unlikely, does anyone with a more mid tier rig have any recommendations?

I've found stable diffuse to run quite well on my PC but I'm having a harder time with this.
