Methods: Thirty ICU cases were selected from the Medical Information Mart for Intensive Care IV (MIMIC-IV, version 3.1) database, equally distributed across low, moderate, and high mortality risk groups. SHAP values and predicted risks were provided to GPT-4o using three prompting strategies (P1, P2, and P3) at three temperature settings (0.2, 0.6, and 1.0).

No significant temperature-related changes were observed under P1 or P2 in GPT-4o. In GPT-4o-mini, report quality remained consistent across all temperature settings, demonstrating that the beneficial effects of temperature modulation are evident only in higher-capacity models with sufficient reasoning capability.
