If you have a local GPU with at least 8GB VRAM, then do a local install of "text-generation-webui" (
You must be registered to see the links
) and pull down a suitable NSFW text LLM from huggingface. I've had fun with some of "TheBlokes" nsfw models like Horny Echidna or Wizard Vicuna, but that was more and 1 year ago so there are probably better models around now. If you have a low Vram card (i.e. 8gb or lower) then you'll need a heavily quantized or low parameter space model.
There was an extensive thread about this topic in this DevTools subforum, but has probably dropped off the first page by now....
Oh, found it:
