Researchers have developed OPINE-World, a novel LLM agent designed to learn programmatic world models from interaction. This system uses a loop of hypothesis and testing between two cooperating agents to synthesize a world model in code, which is then refined through counterexample-guided inductive synthesis. OPINE-World is particularly adept at handling pixel-rendered environments by flexibly hypothesizing object structures and uses a Bayesian measure called ontology error to guide exploration. In evaluations on the ARC-AGI-3 benchmark, which withholds object vocabulary and goal semantics, OPINE-World successfully solved 20 out of 25 games without per-game training and achieved a high action-efficiency score.
