Episode notes
Multi-Agent Teams Outperform Single Models
- Microsoft study used multiple AI agents that talk to each other to diagnose complex cases stepwise.
- The multi-agent approach simulates expert panels and improved diagnostic reasoning beyond single-model Q&A.
AI Narrows Patient–Doctor Knowledge Gap
- Patients are becoming better informed using AI tools to understand medical jargon and prepare questions.
- This reduces information asymmetry and enables more peer-like conversations with physicians.
Realistic Workflow Beats Exam Questions
- The study moved beyond exam-style multiple choice to a realistic iterative diagnostic workflow.
- Agents were given roles like test chooser and devil's advocate to force stepwise, resource-aware decisions.
