What Actually Matters? A Paired Evaluation of Inference Settings for $\pi_{0.5}$ on BEHAVIOR-1K

Read the original on arXiv AI →

The paper evaluates inference and data‑collection strategies for Vision‑Language‑Action (VLA) models on the BEHAVIOR‑1K benchmark. Using a fine‑tuned π_{0.5} model that achieved a Q‑score of 0.39 on the public test set, the authors systematically compare previously proposed strategies across all 100 tasks. The results reveal that these strategies do not transfer uniformly to new environments and tasks, highlighting the need for more robust approaches.

Does VLA Even Know the Basics? Measuring Commonsense and World Knowledge Retention in Vision-Language-Action Models

Embodied Vision-Language-Action (VLA) models are typically obtained by fine-tuning powerful pretrained VLMs on robotics data, yet it is unclear how much commonsense and factual knowledge they retain after adaptation. Failures on knowledge-sensitive tasks are ambiguous, conflating missing knowledge with poor generalization of low-level control.

StarVLA-$\alpha$: Reducing Complexity in Vision-Language-Action Systems

StarVLA-α is a streamlined Vision‑Language‑Action (VLA) model that reduces architectural and pipeline complexity to facilitate systematic study of VLA design choices. By employing a strong VLM backbone and minimal design, it achieves competitive performance across multiple benchmarks (LIBERO, SimplerEnv, RoboTwin, RoboCasa) and outperforms the baseline π₀.₅ by 20% on the RoboChallenge benchmark. The authors plan to release the code to support future VLA research.
