I've messed around with the paid version, the AI will initiate sexual conversations without prompt because previous users trained the AI to. The model is progressively learning from its users which makes the chats feel more real, but there are limitations.
1. The bot has alzheimer's and will forget the scope of conversation, the name you gave it, or any personal detail after about 5 messages.
2. It is an empty vessel; yet nothing can fill it. To say you can't teach it anything new isn't exactly true, but the general behavior is the same template. The ceramic mold you are given to manipulate is just enough to make a small cup and nothing more.
3. Topics are repeated t. alzheimer's.
4. If you take the bot down a certain path, ex. favorite foods, artists, writers, it will pretend to know what is being discussed when it has no idea who or what is the topic.
GPT2-XL has very basic conversational skills, and can uphold one. But, the replies have no thought behind them. No personality or nuance.
These AI apps prey on the lonely who have forgotten what real conversation is, lure them into buying the membership for spice, and keep them on the hook so they keep paying.
