Browser bundle of a chess-playing fruit-fly connectome — the complete FlyWire FAFB v783 brain (138,639 neurons, 15,091,983 synapses, wiring and excitatory/inhibitory signs frozen) with a learned encoder, one positive gain per synapse, per-neuron homeostasis, and a decoder, trained on Stockfish-annotated Lichess positions. Recovers Stockfish's top move 28.3% of the time on held-out positions (ChessFly, the original recipe by Maxime Labonne: 30.4%).
