How much does producing AI cost?

Could you elaborate on the factors that contribute to the cost of producing AI? Is it a straightforward, one-time investment, or are there ongoing expenses to consider? Additionally, how does the level of complexity and sophistication of the AI system factor into its overall production cost? Is there a general price range that one can expect, or does it vary widely depending on the specific needs and requirements of the project? I'm curious to understand the financial considerations involved in the development of AI technology.
