A new survey paper clarifies the boundaries and commonalities among World Action Models (WAMs), which are predictive-action systems designed for decision-making. These models balance representational richness with computational constraints, utilizing various approaches such as large video generation models or language and vision-language backbones. The paper categorizes existing works by what they generate (rendered futures, latent futures, or action reasoning) and their predictive substrate, backbone, action coupling, and deployment regime. It highlights a trend towards generating less of the future while retaining essential control capabilities. AI
