The old Taobot was powered by Microsoft Azure. It was really good for the time, and actually really expensive to run as well.
Our slogan was *No matter how you word the question, our Chatbot utilizes Azure's market leading natural language understanding to give you the right answer.*As the slogan says, it was good at understanding what you wanted, but the problem was that it only returned 1:1 knowledge base articles. That's why we upgraded to ChatGPT, it's more flexible on the input and output side, and combines different things it learned to a fitting answer.
