Hi, I would like to better understand if it is possible to create a chatbot for free trained on a dataset (which I still have to create) on my PC.I was seeing that llama-2 could be a solution but you have to host it.So I understood that an external machine with GPU is needed, but apart from that, is it possible to make a totally private chatbot?I would like to make a small MVP, if so please share with me anything that might be useful .I’m a web dev and I know also python but not the theory below AI
