- WAVE-0 bridges VLA policies and world action models with latent future prediction
An arXiv paper introduces WAVE-0 (World-model-Augmented VLA Execution), which uses a lightweight 257M-parameter latent world model to connect a pretrained VLA's semantic understanding with explicit future prediction, so anticipated action consequences directly condition the action expert and unify latent planning, future prediction and action generation. The world model is trained directly on ground-truth robot actions with a counterfactual ranking objective, requiring neither pixel reconstruction nor large-scale video pretraining. The authors report success rates of 91.47% on RoboTwin 2.0 and 98.7% on LIBERO, plus 88.0%, 61.4% and 75.0% on LIBERO-Plus, LIBERO-Pro and LIBERO-Para, and a real-world improvement of π0.5 from 38.3% to 73.3%.
