Design a Multi-Agent Medical Diagnosis System
Explore the design of a multi-agent AI system simulating a clinical setting for medical diagnosis. Learn to architect agent roles, enable collaboration among doctor agents, and implement mechanisms for continuous improvement without retraining. Understand how such systems can surpass static benchmarks by mimicking real-world medical decision processes and evolving through experience.
We'll cover the following...

In this lesson, you will apply everything you have learned about agentic system design to solve a complex, real-world challenge. You will be guided through a thought exercise to architect a multi-agent “AI Hospital,” a simulated clinical environment for evaluating and improving the diagnostic capabilities of LLM-based doctor agents. This exercise will test your ability to design agent roles, orchestrate collaboration, and build mechanisms for long-term agent improvement.
The challenge of medical diagnosis with AI
Medical diagnosis is one of the most complex and high-stakes tasks in human decision-making. Diagnosing a patient involves dynamic, multi-step reasoning, unlike answering a trivia question or recommending a movie. A doctor must gather a patient’s history, interpret symptoms, order and analyze tests, and then integrate all that information into a coherent diagnosis and treatment plan. Every decision carries weight, and mistakes can have serious health consequences.
Today, most evaluations of large language models (LLMs) in medicine rely on static benchmarks, such as multiple-choice exam questions. While useful, these benchmarks fall short. They ...
