I wouldn't bother with CAI. The developers are dead set on sanitizing the entire platform with a very, VERY strict content filter. The AI is actually at it's lowest point since it's launch back in October. Really dull and stupid. Can't remember shit, gets stuck in loops constantly. And then you have the filter butting in every other message with fake "chat error" messages to delete and fine tune content. It's just not worth it.
Instead you should check out something called Pygmalion. It's open source and being backed by the community largely. It's also not censored. The model is still basically an infant (2 months old) but it's getting better all the time. You can find more information over on Reddit or the /CAIG/ thread over on /g/
