New VLA-Retain benchmark reveals vision tuning harms robot model robustness

A new benchmark called VLA-Retain has been introduced to evaluate the impact of vision tuning on Vision-Language-Action (VLA) models used in robotics. The benchmark reveals that fine-tuning these models for specific tasks, such as handling camera-view or sensor-noise data, often leads to a decrease in performance on other, related tasks. This cross-dimensional effect, where gains on target conditions do not predict retention and can even result in performance loss elsewhere, highlights the need to consider retention alongside target gains when adapting VLA models.

IMPACT Highlights the trade-offs in fine-tuning VLA models, suggesting that performance gains in one area may come at the cost of robustness in others, impacting real-world robotic applications.
