LLMs can be implemented to be formally deterministic but if you ask them to solve a specific problem instance you have not seen before, you cannot generally guarantee they will do so reliably. So you're correct in a pedantic sense but I think GP's perspective is more useful if you are problem solving.

It's not pedantry. The parent commentator is simply stating something incorrect and its very misleading at a conceptual level for people who won't think about it too much. And you can guarantee they will do so reliably unless you parameterize the input with some "truly" (yea i know) random input.
