A recent study revealed significant inconsistencies in AI models' ability to accurately estimate carbohydrate counts from food images, posing potential health risks for diabetes management. Across over 26,000 queries, models like OpenAI's GPT-5.4 and Google's Gemini 2.5 Pro exhibited wide variations in carb estimates for the same meal, with some discrepancies large enough to necessitate dangerous insulin dosing errors. The research also highlighted instances where models misidentified foods or hallucinated ingredients, further compromising their reliability for critical health applications. AI
