Researchers from Meituan and Beijing University of Aeronautics and Astronautics have introduced LIBERO-X, a new benchmark designed to rigorously test the robustness of Vision-Language-Action (VLA) models. Unlike previous benchmarks that focused on average success rates, LIBERO-X employs a five-level progressive testing protocol to simulate real-world deployment challenges such as object repositioning, scene changes, novel objects, visual interference, and instruction rewrites. Experiments revealed that prominent VLA models exhibit significant performance degradation on LIBERO-X as difficulty increases, particularly in scenarios involving topological changes, unseen objects, and semantic instruction variations, highlighting a gap in their ability to generalize under distribution shifts.
