Researchers have developed Valdi, a novel approach to world models for Model Predictive Control (MPC) that integrates latent diffusion dynamics models with end-to-end online training. This method aims to address the challenge of fast and expressive dynamics prediction required for MPC by using diffusion models, which are typically slow for real-time planning. Preliminary experiments on the CarRacing environment indicate that Valdi, with a single diffusion step, can achieve performance comparable to deterministic MLP baselines, though it highlights a trade-off between predictive multimodality and control performance.
