How do you purchase AI?

How do you actually go about purchasing AI technology? Is it a simple process like buying a new phone or computer, or is it more complex? Do you need to have a certain level of technical expertise to acquire AI? Are there any legal considerations or restrictions that you need to be aware of when purchasing AI? I'm curious about the steps involved in the process and how one would navigate the landscape of AI providers and offerings to find the right solution for their needs.
