Chatbot vs AI Agent (LangGraph + Local LLM)

This project demonstrates the difference between:

• a chatbot (single prompt → response)
• an AI agent (decide → act → observe → respond)

Both use the SAME local open-source model (llama3).

Key Insight

Agents are not smarter models. They are better systems.

Stack

• LangGraph
• SQLite

How to Run

1. Initialize database: python -c "from db import init_db; init_db()"
