WorldCoder-Bench: leaderboard
Metric: Verification coverage (%; share of hidden assertions that pass per task, averaged over tasks) on WorldCoder-Core, the 205-task hard evaluation split: from a natural-language task (optional .glb assets and a visible runtime-state interface) the model writes one self-contained Three.js HTML program zero-shot, and StateProbe runs it in a sandboxed browser and checks hidden, mutation-hardened behavioural contracts over runtime states and transitions; higher is better. Source: arxiv.org. Saturation forecast: Around 2030. 9 models tracked.
