Great work that measures GPT6 Astra as an Embodied Policy by Yu-Mool Shu and Lipxin Zheng.
It further proves with numbers that VLA handles dexterous movement, while the General Model oversees supervision, error correction, and replanning.
Interesting numbers: For the average performance across 10 tasks in RoboDojo, PI0.5 gets 24%, Astra gets 37% but together they achieves 62%. But for RoboLab, Astra itself gets 98%.
As for the contribution, GPT 6 Astra is correcting only 14.4% of the executed control steps and the remaining 85.6% following the actions by PI0.5.
