How LendingTree built a multi-agent mortgage assistant on Amazon Bedrock

LendingTree built a multi-agent mortgage assistant on Amazon Bedrock, using three agents (supervisor, education, matching) coordinated via LangGraph and MCP. The supervisor agent uses Amazon Nova Pro for complex reasoning and Amazon Nova Lite for simpler tasks, and the system leverages Amazon Bedrock Guardrails for compliance and PII protection.

From the source

The Supervisor implements multi-model architecture, automatically selecting between Amazon Nova Pro (for complex reasoning and critical classification) and Amazon Nova Lite (for conversational responses and lightweight classification) depending on what the task demands. This balances reliability with cost.
