FLEX-WAM: Flexible Block-Causal World-Action Models for Long-Horizon Imagination and Planning
World--action models (WAMs) promise a unified model that predicts action-conditioned futures, generates feasible actions, and supports planning in imagination. However, existing joint video--action models often use computationally heavy, fixed-horizon backbones ill-suited to streaming inference and stable long-horizon...
