About

Pluribus defeated top professional players including WPT champion Darren Elias and six-time WSOP champion Chris Ferguson in six-player no-limit Texas Hold'em. Win rate of approximately 5 bb/100 (winning $5 per hand, about $1000/hour).

The core breakthrough was a new limited-lookahead search algorithm, trained through self-play without any human data. The base strategy was computed in just 8 days on two CPUs, costing only ~$144 — far less than AlphaZero. Featured on the cover of Science, it was runner-up for 2019 Breakthrough of the Year.
