Inference is not always the answer.
Some capabilities need a model because the work involves language, ambiguity or synthesis. Others should be deterministic software, and building them any other way is malpractice dressed as innovation. A model that is right most of the time is a liability in a path where being wrong once is unacceptable.
This is not a hedge about AI. It is why most of what runs on a deployment day to day is governed business software, with AI as one capability among several.
