Researchers at Google Research have introduced SymptomAI, an experimental conversational AI agent based on Gemini Flash 2.0 for symptom assessment and differential diagnosis. In a national study involving 13,917 participants, the system demonstrated differential diagnostic accuracy at least as good as real physicians in over 50% of cases, with agentic questioning strategies significantly outperforming passive mode. Additionally, AI diagnoses correlated with physiological signals from wearable devices (Fitbit), opening possibilities for large-scale research.
