To everyone "just experimenting" with LLMs:
I urge you to go look up how much money OpenAI is losing each month, and then figure out how much they have to charge to turn a profit. That is the minimum they are going to charge, eventually.
They are in a land-grab / tech bubble mode right now, willing to burn money to gain customers like you, who are going to bake their stuff into products, workflows, etc., and then when the bubble pops, you are going to be stuck paying for it.
