How much does the Tesla AI cost?

I'm curious to know, could you provide some insight into the cost of the Tesla AI system? I understand that it's a highly advanced technology and I'm eager to learn more about its pricing structure. Is it a one-time fee, or does it come with ongoing costs? And how does it compare to other AI systems in the market in terms of cost-effectiveness? I'm looking to make an informed decision and would appreciate any information you can provide.
