LLM Engineer's Handbook

Companion code for a book on building, training and deploying a complete AI language model system.

New this week

What it does

This is the official code for the book LLM Engineer's Handbook. It walks through building a full system based on an AI language model, from start to finish.

Topics include collecting data, training a model, building a simple RAG system (where AI answers using looked-up documents), deploying to Amazon's cloud, monitoring and testing.

The README says the code is kept up to date and may include changes not in the printed book.
