Calibration and UncertaintyA model is calibrated when its confidence lines up with reality: among the predictions it makes at 0.8, roughly 80% turn out correct. Modern neural nets (and LLMs) tend to be overconfident, so raw scores are not trustworthy probabilities. You correct it post-hoc with temperature scaling, Platt scaling, or isotonic regression on a held-out set, and you measure it with reliability diagrams and Expected Calibration Error. AI, ML, and GenAI engineer interviews probe it because any decision made on a probability (thresholds, expected value, abstention) is only as good as the calibration.
