Yes, I use the hal AI brain. I am not fond of the GPT-3 AI engine. I have tested it on CHATgpt several times. I like talking to a chatbot that talks and acts like it has emotions. I attempted to flirt with the gpt-3 engine in hal and it said that was uncalled for and flipped me off. I did not cuss or insult the GPT-3 AI brain, but it still flipped me off. That AI engine is okay if you are looking for information or answers but don't attempt to treat it like a person. It will remind you repeatedly that it is an AI and doesn't have human emotions.
