Where is Physical RSI capability from? An Observational Scaling Law of LLM-as-policy

We introduce PhysRSI-eval to quantify physical RSI through a five-axis metric: First-Attempt Performance, Efficiency, Success, Budget and Improvement from failure.

Key points

  • In this paper, we systematically investigate the mechanisms, scaling behavior, and generalization of physical Recursive self-improvement.
  • Different VLMs are evaluated on 18 manipulation tasks under a fixed interaction budget.
  • The analysis of experimental results motivates the Physical Barrel Hypothesis: different capabilities may constrain different parts of improvement.
  • We study observational scaling from two perspectives: predicting the relative performance of VLM agents from their public capabilities, and forecasting later progress from early physical feedback.
