Dataset from the paper VGC-Bench: Towards Mastering Diverse Team Strategies in Competitive Pokémon.

Code: vgc-bench

Contains data for 16 Gen 9 Pokémon VGC formats, all filtered for Open Team Sheets (OTS). See:

  • scrape_logs.py for the code that scraped these 705,487 logs from the Pokémon Showdown replay database
  • logs2trajs.py for the code that reads the logs from player 1 and 2's perspective, yielding 1,410,934 trajectories (99.997% successful log read rate), or 13,108,147 transitions
  • pretrain.py for the code that uses those ~13M transitions to train a policy with behavior cloning

Each provided json file contains data in the following format:

{
    "<battle-id>": ("<time-of-battle-in-epoch-seconds>", "<battle-log>"),
    ...
}
