LLM confidence scores are decorative, not measured, warns technical post

A recent technical post highlights the critical difference between a model-generated confidence score and a calibrated probability. The author argues that numbers reported directly by an LLM during its generation process are merely decorative, reflecting how confident the model sounds rather than an actual measurement of accuracy. True calibration, the post explains, can only be achieved through external bookkeeping that compares reported numbers against actual outcomes over time. This distinction is crucial for systems that automatically accept or reject model outputs based on confidence thresholds, as decorative numbers can lead to flawed decision-making. AI
