Researchers have developed new metrics to assess the instability of Large Language Model (LLM) persona-driven generations (PDGs) in multiple-choice question answering (MCQA) tasks. Their findings indicate that instability varies across different model families, sizes, and question domains, with mathematical and commonsense questions exhibiting greater instability. The study also found that task prompt format significantly impacts prediction instability, more so than hyperparameters like temperature. Furthermore, the research highlights a relationship between instability and task accuracy, suggesting that specific experimental settings can lead to distinct best and worst-performing personas for given tasks.
