A new paper argues that large language models are fundamentally incapable of reliable causal discovery due to inherent limitations in their training paradigms. Researchers have proven that methods like supervised fine-tuning and direct preference optimization lead to models that cannot distinguish between causal graphs generating similar observational data. To overcome this, the paper proposes an "Agentic Causal Bayesian Optimization" (A-CBO) approach, which uses a frozen LLM as an interventional oracle and an external Bayesian loop to concentrate beliefs over candidate graphs, achieving provable convergence without retraining the LLM.
