Scott Alexander and Edwin Chen are conducting a bet to determine whether an image model has achieved compositionality, with Gary Marcus serving as a substitute arbiter. The resolution criteria is based on whether Edwin can access the top models of late 2023 or use public demos and his own judgment, with defaulting to false if no clear progress is made. A resolution of "likely true" would imply that current AI models have successfully demonstrated compositionality. Gary Marcus will be used as a substitute arbiter if neither Scott Alexander nor Edwin Chen can resolve the question, resulting in an unclear outcome. The bet's exclusive authority lies with Scott Alexander's judgment, which will govern the market's resolution.
