Now, Libratus’ technology is being adapted to take on opponents. "It was improving very rapidly, where it went from being a mediocre player to basically a world-class-level poker player in a matter of days and weeks. In 2017, a poker bot called Libratus made headlines when it roundly defeated four top human players at no-limit Texas Hold ‘Em. The bot quickly became a stronger player. Pluribus - so-named because it takes on many opponents at once - learns by playing against itself over and over and remembering which strategies worked best. He'd take on four tables full of them at a time, and he'd alert the computer scientists who designed the bot when it made a mistake. "It's just me and then five versions of this AI poker bot, which I would play against every day, thousands of hands," Elias said. Researchers say they have designed a bot called Pluribus capable of taking on poker professionals in the most popular form of poker and winning.įour-time World Poker Tour title holder Darren Elias helped test the program's skills, playing Texas Hold 'em against a whole table of the bots. But a game like poker, specifically six-player Texas Hold 'em, has been too tough for a machine to master - until now. In artificial intelligence, it's a milestone when a computer program can beat top players at a game like chess. During one experiment, the poker bot Pluribus played against five professional players.
