World Model POSG Game - Coverage: leaderboard
World Model POSG Game - Coverage: Permutation-invariant structural agreement (0-1). LLM-generated world models, arXiv 2611.14419v1: nine game cases times three requests per model. Game structural metrics use final artifacts including recorded repairs, permutation-invariant matching. Initial requests: temperature 0, max output 16384, reasoning disabled. Situational S1-S9 feature-multiset metrics are conditional on probe-passing candidates, denominators retained in pinned n column. Hosted IDs identify Llama 3.3 70B Instruct and DeepSeek V4 Flash 0731. Automated semantic checks are diagnostic and not human-validated; not ingested as semantic capability.
Metric: Permutation-invariant structural agreement (0-1). Source: arxiv.org. Saturation forecast: Around June 2028. 5 models tracked.
