Where this applies
Japan. A study that tested GPT-4o, GPT-4o-mini and GPT-4o with retrieval on 599 publicly available multiple-choice questions from the 2022–2024 national examinations. All passed the 60% threshold; GPT-4o-RAG scored highest at 83.5%, did better in applied and clinical nutrition, but showed limited performance on numerical questions, and the authors say limitations in numerical reasoning and individualized guidance warrant further development. Exam questions, not patients.
What this means
A second country's licensing exam shows the same pattern: the knowledge is there, the patient-specific numbers are not.
What it does not yet show
Multiple-choice exam questions; not a test of guidance for real patients.
What you can check
Open the Endocrine Journal article on GPT-4o and Japan's national dietitian examinations and find "limited performance on numerical questions".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
