A new research paper introduces SCSuff, an information-theoretic metric designed to evaluate the sufficiency of free-text explanations generated by large language models (LLMs). The study posits that explanation sufficiency can be distribution-dependent and proposes using the LLM itself to generate alternative inputs, thereby capturing its beliefs. Experiments indicate that LLM explanations are generally insufficient and show a weak correlation with model size or accuracy, though SCSuff scores can be predicted from internal model representations.

IMPACT This research could lead to more reliable and trustworthy explanations from LLMs, crucial for high-stakes applications.
