LaWAM (Latent World Action Model) is a robotics policy model that exposes predictive dynamics to robot policies through compact latent visual subgoals instead of reconstructed future video. It achieves state-of-the-art or competitive success rates across LIBERO, RoboTwin, and real-world manipulation tasks while maintaining low-latency inference.
LaWAM introduces a latent world-model interface for VLA policies. It predicts future observation features in a frozen visual feature space and injects them as latent visual subgoals for action generation.

GitHub repository for instructions on environment setup, dataset preparation, SFT training, and running inference on the LIBERO and RoboTwin simulators.
