BadWAM: World-Action Models That 'Dream Right but Act Wrong'
arXiv / HuggingFace Daily Papers·low signal
arXiv 2607.15207 (38 upvotes, July 17) isolates a specific failure mode in world-action models — the model's internal rollout of what should happen is accurate, but the action it emits diverges from that rollout. It's a useful diagnostic frame beyond robotics: the same reasoning-vs-execution gap shows up whenever an agent produces a correct plan and then takes a different step.
