Build Your First AI Agent with One Tool Call

An AI agent is a software system that uses a large language model to call one or more tools in a loop to achieve a goal. This tutorial provides a step-by-step guide for building a simple AI agent using Python, Ollama for running a local LLM, and a SQLite database. The example agent is designed for a fictional online shop and can answer questions about order totals by calling a specific Python function. This function queries the database for the information, which is then returned to the LLM to formulate a natural language response.
