PhysRSI - Initial Performance: leaderboard
PhysRSI-eval (2026): six model/runtime systems on 18 robotic simulation tasks; initial K0 scores averaged over three runs per task, followed by iterative K1–K17 revisions. Codex uses 4200-second reasoning/1800-second revision budgets; Claude Code uses 4200/600. Runtime settings are part of these descriptive system comparisons. Normalized Score (0–1); higher is better.
Metric: Normalized Score (0–1). Source: arxiv.org. Saturation forecast: Around June 2028. 6 models tracked.
