Researchers have identified a critical issue in compact world models that use language goals to ground spatial relations, such as "put the red block left of the blue block." They found that these models often exhibit "instruction leakage," where the model's accuracy is derived from transcribing the instruction rather than from actual perception of the scene. This leakage was demonstrated by a significant drop in accuracy when the goal instruction was withheld or altered, indicating the model was not genuinely grounding the spatial relationships. The proposed solution involves keeping the goal separate from the dynamics and supervising the read path to achieve instruction-independent grounding. AI
