A new research paper published on arXiv suggests that the planning capabilities of latent world models, rather than their predictive accuracy, are the primary bottleneck for long-horizon planning. The study, which reproduced experiments on the LeWorldModel for the TwoRoom environment, found that the planner's objective function was the limiting factor. By simply altering the objective function without retraining, the model's success rate at long horizons significantly improved, indicating that the information for accurate planning is present in the model's latent space.
