# Agentic AI in Production: Multi-Agent Workflows & RAG
Simple chatbots that answer generic questions are obsolete. Enterprise software demands Agentic AI—autonomous systems that can plan multi-step workflows, query private SQL databases, execute API tool calls, and verify outputs before returning them to users.
---
### Key Architectural Pillars
1. **Private Vector Search with pgvector**: Storing 1536-dimensional embeddings inside enterprise PostgreSQL databases with row-level security.
2. **LangGraph State Machines**: Structuring agent decision trees as deterministic directed graphs to avoid infinite prompt loops.
3. **Hallucination Guardrails**: Output evaluation models that cross-reference every generated sentence against retrieved source chunks before delivery.
