DMCommunity.org has posted a new April 2026 Challenge that aims to explore how LLMs orchestrate rule-based decision services. It describes three loosely coupled medical services that an LLM can use to help a physician determine the appropriate therapy for a patient with Acute Sinusitis. Below, I will demonstrate how OpenRules builds these services and automatically makes them AI-ready, enabling a natural, user-friendly dialogue between a physician and an LLM.
