Decision models struggle with multiple correct choices, research finds

By PulseAugur Editorial · [1 sources] ·

A new research paper evaluates three decision models—Jev, Liquid d1, and GPT-6 Luna Decisions—on their probability allocation when multiple correct choices are present. The study found that even when models correctly rank all valid options above incorrect ones, a significant percentage (28-50%) of these correct choices were assigned probabilities below the uniform distribution threshold. Furthermore, when presented with identical correct choices, the models exhibited substantial probability disparities, with mean gaps ranging from 17 to 79 percentage points. These allocation issues impact the ability to accurately identify multiple correct choices using probability thresholding. AI

IMPACT Highlights potential flaws in how LLMs assign probabilities, impacting their reliability in complex decision-making scenarios.

    When Multiple Choices Are Correct: Asymmetric Probability Allocation in Jev and Other Decision Models

    arXiv:2610.29217v1 Announce Type: new Abstract: Decision models return normalized probability distributions over candidate choices, which downstream applications can use to select among choices. Although their providers emphasize the reliability of these probabilities, calibratio…
