VLA-REPLICA: A Low-Cost, Reproducible Benchmark for Real-World Evaluation of Vision-Language-Action Models

Published in arXiv, 2026

Alex S. Huang*, Jiahui Zhang*, Shiqing Tang, Yu Xiang

VLA-REPLICA is a low-cost (<$1100), easily reproducible real-world benchmark for evaluating VLA models. Our system provides a consistent environment for policy evaluation anywhere in the world. VLA-REPLICA includes a diverse suite of manipulation tasks and a small-scale demonstration dataset for target-domain adaptation, with real-world evaluation protocols for both in-distribution and out-of-distribution settings.

Robometer: Scaling General-Purpose Robotic Reward Models via Trajectory Comparisons

Published in Robotics: Science and Systems (RSS), 2026

Anthony Liang*, Yigit Korkmaz*, Jiahui Zhang, Minyoung Hwang, Abrar Anwar, Sidhant Kaushik, Aditya Shah, Alex S. Huang, Luke Zettlemoyer, Dieter Fox, Yu Xiang, Anqi Li, Andreea Bobu, Abhishek Gupta, Stephen Tu, Erdem Biyik, Jesse Zhang

General-purpose, video-language-input, dense reward model trained on RBM-1M, a large-scale dataset of over 1M trajectories spanning 21 robot embodiments. Significantly improves robot learning across online RL, offline RL, model-based RL, failure detection, and data retrieval for imitation learning.
