LLM preference judgments lack self-consistency, study finds

A new study published on arXiv has found that preference judgments derived from large language models (LLMs) are not self-consistent. Researchers developed statistical tests to measure how well a single utility function could reproduce these judgments, finding significant inconsistencies across various examples like flight and apartment choices. This suggests that LLM-derived preference data cannot be reliably summarized by a single utility function, potentially impacting agent-based systems that rely on such data. AI

IMPACT Challenges the reliability of LLM-derived preference data for agent decision-making.

    LLM-Derived Preference Judgments Are Not Self-Consistent

    arXiv:2608.17644v1 Announce Type: new Abstract: Agents increasingly interpret a person's natural-language preferences by querying an LLM for numerical preference judgments, e.g., by asking how much the person would be willing to pay for an item. A growing body of work estimates a…
