ConfTuner: Training Large Language Models to Express Their Confidence Verbally

arXiv — cs.CLWednesday, November 26, 2025 at 5:00:00 AM
  • ConfTuner is a newly introduced fine-tuning method aimed at enhancing the verbalized confidence of Large Language Models (LLMs), addressing the issue of overconfidence in high-stakes domains like healthcare and law. This method does not require ground-truth confidence scores, making it a more efficient approach compared to existing techniques that rely on prompt engineering or heuristic estimates.
  • The development of ConfTuner is significant as it seeks to improve the reliability and trustworthiness of LLMs, which are increasingly utilized in critical applications. By enabling these models to express their confidence more accurately, it could enhance user trust and decision-making in various fields.
  • This advancement reflects a broader trend in AI research focused on improving LLMs' performance and reliability, particularly in multi-turn interactions where context drift can lead to diverging outputs. The ongoing exploration of calibration methods and evaluation frameworks indicates a growing recognition of the need for LLMs to provide more nuanced and contextually appropriate responses.
