# Recall

Of all the true matches, how many Vessim finds. Measured at 98% on 60 real product photos. The 2% missed are photos changed so heavily (tiny thumbnails, heavy padding) that the safe choice is to miss them rather than guess. As of October 23, 2026, matching at that line has compared 74,691 photo pairs in the live index.

## Why it matters at Vessim

Recall is the price of being careful: the photos Vessim misses are the ones changed so heavily that guessing would risk a false match.
