    "body_text": "DiabAgent combines an agentic-control framework, a diabetes simulator and a 212-task benchmark built from 32 scenario designs. The agent observes glucose and contextual events, accumulates patient-specific experience and uses medical-device tools to choose actions. With one named frontier model and hourly decisions, the framework reached a reported COGI score of 73.5 versus 71.2 for the OpenAPS baseline; ablations credited individual adaptation and contextual information, and a hybrid of frequent rules with slower agent decisions reduced the decision burden. All results come from a virtual environment. They do not establish safety, clinical benefit or permission for a language model to dose insulin in real patients.",
