Route User Requests to Specialized Agents with GPT-4o Mini

This n8n workflow template automates the routing of user requests to specialized sub-workflows or agents based on natural language input. It starts with a Webhook trigger that receives raw user queries via POST requests from any frontend or API. The core intelligence comes from GPT-4o Mini, which analyzes the input to identify the appropriate agent (e.g., Reminder Agent, Email Agent, Document Agent, Meeting Agent) and extracts the refined user query. Output parsers ensure reliable structured JSON output with keys like 'Agent Name', 'user input', and 'sessionID'.

The workflow employs an Auto-fixing Output Parser to handle any LLM inconsistencies by re-prompting as needed, followed by a Structured Output Parser for strict JSON formatting. A Switch node then dynamically routes the data to the corresponding sub-workflow, enabling seamless delegation without manual intervention.

Benefits include scalable agent orchestration, reduced development time for multi-agent systems, and high accuracy in intent detection thanks to GPT-4o Mini. Ideal use cases: customer support bots routing tickets, enterprise chat interfaces dispatching tasks, or AI assistants in productivity apps handling diverse requests like scheduling reminders, sending emails, generating documents, or booking meetings.
