1) If I understand correctly, I can use a chatbot that responds with AI in real time thanks to the training I can provide. However, as a web developer, I know full well that chats using more advanced AI models cost a lot but provide accurate and perfect responses. However, if you use older, lower-cost models, conversations sometimes don't work at all; they get out of step, out of control, make up, and many other negative things. I need a professional service and would gladly pay a Plus if I could connect a model to the more advanced ones. It's not clear what you're using HERE... but it seems normal that at this price, with unlimited conversations, AI can never be advanced. Please let me know.
