Is Nvidia AI free?

I've been hearing a lot about the advancements in AI and how Nvidia has been a major player in the field. However, I'm curious about the cost aspect. When someone mentions "Nvidia AI," does it imply that the technology or its usage is free? Or are there licenses, subscriptions, or other financial considerations involved? Clarifying this upfront would be very helpful for those of us exploring the possibilities of AI and how we can leverage Nvidia's capabilities without breaking the bank. So, in a nutshell, is Nvidia AI free to use, or are there associated costs that potential users should be aware of?
