My bigger concern isn't the financial cost, it's that the amount represents a degree of energy expenditure. A flat rate might not be advisable and having usage-based pricing may limit energy waste. OTOH I don't know how much energy some of the other recurring things I consume monthly are either.

Maybe we can have a service that's an LLM with shared/cached responses as well as training on its own questions/answers for the easy stuff. Currently my usage is largely as a better search engine as google has gotten so much worse than it ever was, though I imagine I'll find custom things it's useful for as well.
