A parallel connect4 AI player written in a webgpu shader.

Does a minimax evaluation on the current game state, looking 8 moves ahead at all possible game states. Expands the tree out 3 levels which results in 343 game states, those are then each evaluated on a gpu thread to check 5 more moves ahead. All in all it looks at 5,764,801 different game states to make it's decision.

Runs pretty quickly on an M series mac or on a computer with a good gpu. Can be kinda slow if you only have an integrated gpu and probably don't work at all on most phones.
