An AI just claimed another gaming victory over humans by winning a 20-day poker tournament.

The AI, called Libratus, took on four of the world s best Heads-Up No-Limit Texas Hold Em poker players at a Pennsylvania casino.

After 120,000 hands, Libratus won with a lead of over $1.7 million in chips.
