LLM confidence scores lack meaning without reliability diagrams, author argues

By PulseAugur Editorial · [1 sources] ·

A vendor's integration guide for an LLM system is criticized for lacking a crucial reliability diagram. The author argues that without a calibration curve plotting reported confidence against actual correctness, the confidence values are merely "feelings with a decimal point" and cannot be used to build reliable policies or routing decisions. The piece highlights how two systems with identical average accuracy can have vastly different practical utility based on their calibration, emphasizing that a confidence score is only meaningful when accompanied by data showing how often that score accurately reflects the system's performance.

    <h1> Show Me the Diagram </h1> <p>A vendor sends over an integration guide. It has three columns: a confidence value the system emits, the action you are meant to take at each level, and what each call costs. There is a cut-off at 0.8 and a note that below 0.6 you should escalate…
