## AI overview

A tutorial shows how to find computer vision edge cases in unlabeled production images. It uses low-confidence or missing detections, distribution comparisons, confusion matrices, embedding clusters, and a vision-language model to identify difficult images, which are then labeled and used for retraining.

Mine low-confidence predictions from production images, review them with a VLM, then label and retrain.
