A multi-agent system divides work among agents that each handle a specific part of a problem. One agent might classify inputs, another retrieves relevant data, another makes a decision, and another handles the output and follow-up.
Each agent does one thing well, which makes the overall system more reliable and easier to improve. A loan origination system with separate agents for document extraction, credit bureau integration, fraud screening, eligibility assessment, and offer generation is a multi-agent system. Changing the fraud screening logic only requires updating the fraud agent — it does not touch the others.
