Lots of versions of language models like gpt-3 exist, its definitely not sorcery mate. https://github.com/openai/gpt-3

I don't have the hundreds of gigs of vram needed to run these big models locally, I'm using a reverse engineered hacky api to proxy it to my discord bot. The text also mentioned images, which come from stable diffusion not chatgpt. That part I run completely locally, also definitely not sorcery.
