I understand but you can already do that with an LLM, it just comes down to your prompting. It is not exactly the same, but I was asking for a specific use case where that really matters
Any use case where a confidence level is desired and you want that number to actually mean something.
Becuase it is multiple orders of magnitude slower and more expensive to do it with an LLM. Look at Typesafe's Doom demo where they run complex queries tens of times per second for around $7 an hour.
There are classes of problem where this shifts the economics from "paying a human to do this is cheaper than AI" to "the software is now cheaper than the human"
