Key Points

To quantify and decompose prediction variability in multimodal large language models used for dietary nutrient estimation from meal images to support diabetes self-management.
Evaluated multimodal large language model performance on nutrient estimation tasks using food images.
Decomposed sources of prediction variability into image presentation sensitivity versus intrinsic model instability.
Identified that model robustness is compromised by both variations in visual presentation and intrinsic model stochasticity.
Established the necessity of accounting for and mitigating prediction variance to make automated dietary assessment clinically dependable.

Abstract

Nutrient estimation from meal images by multimodal large language models can support diabetes self-management, but its robustness is limited by variability driven by both sensitivity to visual presentation and inherent model instability. Accounting for and mitigating this variability is essential for robust AI-assisted dietary assessment.
