[GRCCP] - Athens C++ Meetup

Marios Aspris will talk about how to take a practical, application-driven approach to leveraging llama.cpp in modern C++ projects. We will cover:

• A high-level introduction to LLMs, focusing on practical applications rather than mathematical theory.
• Where to find open-source LLM models and how to convert them to the GGUF format for use with llama.cpp.
• How to integrate llama.cpp into your C++ projects using #include "llama.h", with live demonstrations of running inference on a laptop.
• An overview of Retrieval Augmented Generation (RAG) systems from an application perspective—what they are, the benefits for custom data, and how to build a simple RAG pipeline with llama.cpp as the inference engine.

By the end of the session, you'll understand how to use llama.cpp to build efficient, private, and customizable LLM-powered applications in modern C++, and how to set up a RAG system for your own data and business needs.
