Google Research and DeepMind developed AMIE (Video), an AI system demonstrating performance comparable to or exceeding human primary care physicians in real-time video consultations. The system achieved a 91% diagnostic accuracy in its top differential diagnosis, outperforming PCPs' 77%, and significantly improved patient communication and perception capabilities over text-based AI.

Key insights

  • Integrating real-time audio-visual perception significantly enhances AI's clinical reasoning and information gathering, particularly for physical observation and guided examinations.
  • Patient actors strongly prefer video consultations over text for conveying health concerns, ease of use, and feeling understood, highlighting the importance of multimodal communication in healthcare.
  • An asynchronous multi-agent architecture enables low-latency dialogue (2.6-second mean turn latency) while allowing for deeper, continuous clinical reasoning and perception.
