Researchers have developed a novel method to optimize large language models (LLMs) for assessing causality in pharmacovigilance, aiming to improve the accuracy of identifying adverse drug events. A study utilizing OpenAI's GPT-5.2 model and the FDA Adverse Event Reporting System (FAERS) demonstrated that a specific metric, the Entropy-Weighted Agreement and Cosine Similarity Score (EWACS), could guide Bayesian optimization to significantly enhance LLM-expert agreement. While temperature optimization did not show a universal effect, case-specific temperature adjustments yielded meaningful improvements, suggesting a path toward more reliable AI-assisted pharmacovigilance.
