LLM explanations for credit risk fail despite predictive model gains

Researchers have developed a multi-scale stacking ensemble for credit risk prediction that integrates gradient-boosting learners and a residual network, achieving a test ROC-AUC of 0.9539. While this ensemble shows a small but statistically significant improvement over single models, the narrative explanations generated by a language model for credit risk decisions were found to be unreliable. The study revealed that the LLM often failed to accurately reflect the model's reasoning, sometimes naming incorrect risk factors or introducing features not provided to it, indicating a need for rigorous verification of LLM-generated explanations.
