  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.
