LLMs assessed for causal understanding via sentence reversal and entropy production

Researchers have explored a novel method to assess an LLM's understanding of event order and causality by reversing sentence sequences within texts. This approach, inspired by stochastic thermodynamics, quantifies irreversibility by comparing the likelihood of forward and reversed sequences, a metric known as entropy production. Experiments using GPT-2 and Qwen3-4B-Base suggest that models generate sequential events with probabilities reflecting their order, offering a quantitative probe into their internal "world models" without directly measuring physical heat output.
