• FAQ
• Links
  • Getting-Started - Download and run Leela Chess Zero if you want to contribute or play games.
  • See recent test match games - Click on the first row, first column, then pick a game. These games are played between recent versions of the engine to measure progress. They are blitz games played with 800 playouts (around 1 second) per move.
  • See recent self-play training games - Scroll to "Active Users", pick someone, then pick a game. These games are how Leela Chess Zero trains herself. They are played with extra randomness turned on so it can discover new good (and bad) moves. This means the quality of these games is lower than the match games.
