Researchers have developed a new method to evaluate the logical consistency of large language models (LLMs) by analyzing query-key alignments within transformer attention heads. This technique, termed the "QK-score," offers a lightweight and scalable approach to assess the coherence of intermediate reasoning steps generated by models, particularly those using Chain-of-Thought prompting. Empirical validation on various logical reasoning benchmarks demonstrated the QK-score's robustness and ability to differentiate valid from invalid inferences across models ranging from 1.5B to 70B parameters.
