Capstone u2013 Build and Ship a Multi-Agent Service·Lesson 24 of 24·60 min

Design and deploy a live multi-agent system

This lesson is for enrolled learners

Concept This capstone asks you to bring together every module into one shipped system: pick a domain (customer support, research assistant, or data analysis), design a multi-agent architecture with at least one orchestrator and one specialist agent (Module 4), ground it with a RAG pipeline over real documents (Module 3), wire in tool use (Module 2), and deploy it as……
