150k sounds like a LOT… what’s your use case for the app?

It seems for any particular problem/comexity there is an estimate of how many LoC is needed (written by humans, good coding practices). And after reaching maturity (and not increasing scope) the LoC converges.

My experience with LLMs so far is it’s a constant battle to not explode the LoC. There’s always pressure away from “maintainability” and a “small elegant cohesive” codebase.
