AI-Powered Demo Call Center with Grok and Persistent Memory
detail.loadingPreview
This n8n workflow provides a comprehensive demo of an AI-powered call center, featuring advanced large language model (LLM) integration, persistent chat memory, and smart rate limiting. It showcases how to build intelligent, context-aware customer service agents that can interact with external services and manage user sessions effectively.
About This Workflow
Dive into the future of customer interaction with this n8n Demo Call Center workflow. Designed to showcase the power of AI automation, it integrates xAI's Grok-2 LLM for intelligent conversation generation. The workflow features robust session management and persistent chat memory using Redis and PostgreSQL, ensuring every interaction is contextually rich. It also implements crucial rate limiting to manage usage and demonstrates how an AI agent can invoke external tools, such as a 'Taxi Service,' to perform real-world actions. This template is perfect for understanding the foundational elements of an advanced AI-driven customer service system.
Key Features
- Intelligent AI Agent (Grok-2): Powers conversations with xAI's Grok-2 LLM for nuanced and context-aware responses.
- Persistent Chat Memory: Utilizes PostgreSQL and Redis to maintain conversation history across sessions, ensuring continuity and personalization.
- Robust Rate Limiting: Prevents abuse and manages resource consumption with a configurable chat limit per session (e.g., 30 chats per 90 seconds).
- External Tool Integration: Demonstrates how the AI agent can trigger and interact with other n8n workflows or external services (e.g., 'Demo Taxi Service').
- Scalable Session Management: Efficiently handles user sessions and data storage for dynamic call center operations.
How To Use
- Set up Redis & PostgreSQL: Ensure you have Redis and PostgreSQL instances accessible by n8n for session and chat memory storage. Update connection details in
Session,Rate Limit,Postgres Chat Memory,Load User Memory, andSave User Memorynodes. - Configure LLM Credentials: Add your xAI Grok API key to the
xAI @grok-2-1212node's credentials. - Adjust Rate Limits: Modify the notes on the
Rate LimitandIf Ratednodes (e.g., '30 CHATS', 'TTL 90s') and adjust parameters if needed to set your desired chat frequency and duration. - Customize AI Agent: Update the
AI Agentnode's prompt, system messages, and tool definitions to match your specific use case and integrated services. - Integrate External Tools: If using tools like the 'Taxi Service' demo, ensure the linked workflow exists, is correctly configured, and its ID is referenced in the
Taxi Servicenode.
