Microsoft has introduced an AI-powered diagnostic tool that mimics a virtual team of doctors, working collaboratively to identify complex diseases faster and more accurately. Called the "AI Diagnostic Orchestrator," it uses a debate-based approach among five AI agents and has proven to be nearly four times more effective than humans. It also reduces unnecessary tests, cutting medical costs significantly. Powered by top AI models including GPT-4Bo from OpenAI, the tool will soon be integrated into Microsoft Copilot and Bing Search.
