https://www.quora.com/Which-chess-engine-would-be-stronger-Alpha-Zero-or-Stockfish-12/answer/Felix-Zaslavskiy explains that it beat <Stockfish (chess)> 8. But then Stockfish was developed further and would start to beat it. We know this because although AlphaZero was closed source, they released the <trained artificial neural network>, so it was possible to replay AlphaZero at its particular stage of training.
