How much is node AI?

Could you please elaborate on the pricing of node AI? I'm particularly interested in understanding the various factors that might affect its cost. Does the cost differ based on the complexity of the tasks it performs? Or is it dependent on the amount of data processed? Are there any upfront investments required, or is it a subscription-based service? Also, I'm curious to know if the cost scales linearly with increased usage or if there are any discounts for bulk purchases. Lastly, how do the pricing models of node AI compare to similar technologies in the market? Your insights would be greatly appreciated.
