This New App Uses AI To Grade Tuna Freshness

Sushi is only as good as the fish wrapped inside its barrel of rice and seaweed. If the tuna, yellowtail, or salmon isn't fresh, it not only looks gross, but renders the whole roll underwhelming in flavor and texture. To keep things from getting fishy, a Japanese company has developed a new mobile app that uses artificial intelligence to grade the freshness of cuts of tuna on sight. Aptly named Tuna Scope, the system uses thousands of cross-sectional images of tuna tails as training data to learn what good quality tuna looks like. According to the Tuna Scope website, trained fishmongers use the tuna tail as a "road map" detailing the fish's flavor, texture, freshness, and overall excellence.
