AdvSim

Pokémon Showdown's [Gen 3] Random Battle, played in your browser against AI trained with a massively parallel GPU battle engine built to exactly match Showdown's simulator.

• MCTS: a Monte Carlo tree search guided by the PPO network.
• PPO: a neural network trained with proximal policy optimization on the engine with self play.
• Emerald-style AI: the strongest-looking move each turn, with Pokémon Emerald's logic for replacements.
• Random: any legal choice.

Everything runs on your device! The AI is also not cheating, it only guesses based upon what it has seen of your team.
