# Prompt Engineering Hands-on


- **Date:** Wednesday, Jul 8, 2026
- **Time:** 11:00–13:00 (120 min)
- **Room:** Room M2 (40 Seats)
- **Event:** World Congress 2026 Europe

## Description

This hands-on workshop teaches prompt engineering by working directly with Large Language Models. You'll learn how LLMs function under the hood and master practical techniques to get better results from them.

We'll use Google Colab for interactive coding and Groq's API for fast inference with open models—both free to use. You'll work hands-on with real LLMs, learning to craft effective prompts and apply advanced reasoning techniques you can immediately use in your own projects.
