AI Ataraxos beats best Stratego player using just 16 GPUs

Researchers from Carnegie Mellon, MIT, NYU and Stanford built Ataraxos, an AI that beat Pim Niemeijer, arguably the best Stratego player ever, 15-1 with four draws. Training took only 16 GPUs and a few thousand dollars, versus an estimated $3-4.5 million for DeepMind's DeepNash.

• Ataraxos beat Pim Niemeijer in 15 of 20 games, with four draws
• Training used 16 GPUs for a week and cost a few thousand dollars
• DeepMind's DeepNash trained 2-3 months on 1,024 Google chips
• At the 2025 World Championship the AI won 38 of 40 games
