PolyBridgeBench: leaderboard

Metric: Success@3 (%; share of all 189 executable Poly Bridge levels (149 core structural and 40 compositional); the model sees the scene image and structured constraints and returns a complete node, member and material topology; deterministic legality checks gate native dynamic physics execution, failed rollouts return visual evidence for repair; success when the vehicles cross within at most three model calls and three physics attempts; temperature 0.2 where exposed; strict budget: each level enforces the material budget calibrated from a manually built reference design, the primary setting). Source: arxiv.org. Saturation forecast: Around December 2026. 6 models tracked.
