This image shows a new medical research project from Microsoft called the AI Diagnostic Orchestrator. MAI-DxO achieves 85% accuracy on complex medical cases whilst spending less on diagnostic tests than human physicians, who averaged just 20% accuracy. The purple line traces MAI-DxO’s performance across different budget constraints, consistently outperforming individual AI models from OpenAI, Google, and others. The orchestrated AI system doesn’t just diagnose better, it does so more efficiently, ordering fewer unnecessary tests. This Pareto frontier visualises how AI has crossed a threshold, delivering both superior medical reasoning and potentially reducing the pressure on healthcare systems.
