An LLM is an extremely complex thing used for all manner of purposes. The hope that there would be some simple pricing construct that would map nicely to value provided is a pipe dream.

Pricing per token is at least reasonably straight forward. If you aren't getting value, you don't use the service. One doesn't buy a Ferrari and then complain that in their town Ferrari doesn't help them pick up women and hence it should cost less.

I'd say it's more like going to a Ferrari dealership and they tell you they will build a car for you and bill you per gram of parts used. It might also not work. And they might also not build it ever, really — but they will bill you for any attempts to build it.
