Google Research has unveiled a conceptual framework for a Personal Health Agent (PHA), an LLM-powered system designed to offer personalized health insights. The PHA utilizes a multi-agent architecture, dividing tasks among specialist sub-agents for data science, domain expertise, and health coaching. This research prototype analyzes multimodal data from wellness devices and health records, aiming to provide evidence-based guidance and a tailored coaching experience. The framework was evaluated using a dataset from an IRB-reviewed study involving approximately 1200 users, with extensive automated and human assessments. AI
