In Major AI Win, Libratus Beats Four Top Poker Pros

Libratus, artificial intelligence developed by Carnegie Mellon University, has beaten four of the best heads-up no-limit Texas hold’em poker players in the world in a 20-day competition. Its mastery of imperfect information suggests a multitude of real-world applications.

Marking a major step forward for artificial intelligence (AI), Libratus, an AI developed by Carnegie Mellon University (CMU), has resoundingly beaten four of the best heads-up no-limit Texas hold’em poker players in the world in a marathon, 20-day competition.

After 20 days and a collective 120,000 hands played, Libratus closed out the competition Monday leading the pros by a collective $1,766,250 in chips.

“I’m just impressed with the quality of poker Libratus plays,” pro player Jason Les, a specialist in heads-up no-limit Texas hold’em like the other three players, said at a press conference yesterday morning. “They made algorithms that play this game better than us. We make a living trying to find vulnerabilities in strategies. That’s what we do every day when we play heads-up no-limit. We tried everything we could and it was just too strong.”

Les lost $880,087 worth of chips to the AI. Fellow player Jimmy Chou lost $522,857 in chips to Libratus.

“This has probably been the most challenging experience in my life,” he said.

“It was a pleasure battling, but we really got beat down,” added Daniel McAuley, of Scotland, who dropped $277,657 to Libratus.

Dong Kim had the strongest showing against Libratus, dropping only $85,649 in chips to the AI over the course of the 20-day tournament.

“Even in the poker community, this is a really, really strong showing,” Kim said of Libratus’ play.
