Hippocratic AI introduces Polaris, a pioneering constellation architecture for real-time patient-AI healthcare conversations, focusing on safety and reducing hallucinations through a sophisticated composition of specialized large language models (LLMs). This system, integrating a primary agent for patient engagement and multiple specialist agents for healthcare tasks, is trained on a rich dataset including proprietary data, clinical care plans, and medical regulatory documents to emulate professional healthcare conversations with empathy and medical accuracy. In comprehensive evaluations involving over 1,200 U.S. licensed healthcare professionals, Polaris demonstrated capabilities on par with human nurses in terms of medical safety, clinical readiness, and conversational quality, showing potential to offload routine tasks from healthcare staff and improve patient care.
