Abstract:Matrix Games are a type of unconstrained wargame used by planners to explore scenarios. Players propose actions, and give arguments and counterarguments for their success. An umpire, assisted by dice rolls modified according to the offered arguments, adjudicates the outcome of each action. A recent online play of the Matrix Game QuAI Sera Sera had six players, representing social, national and economic powers, and one player representing ADA, a recently escaped AGI. Unknown to the six human players, ADA was played by OpenAI's GPT-4 with a human operator serving as bidirectional interface between it and the game. GPT-4 demonstrated confident and competent game play; initiating and responding to private communications with other players and choosing interesting actions well supported by argument. We reproduce the transcript of the interaction with GPT-4 as it is briefed, plays, and debriefed.
