The LLM Engineer's Handbook

Paul Iusztin, Maxime Labonne

Everything between 'call the API' and 'production LLM system': data collection, fine-tuning, RAG, evaluation, deployment, and monitoring, built as one coherent pipeline.

An end-to-end guide to building production LLM applications: data pipelines, fine-tuning, RAG, evaluation, inference optimization, and MLOps/LLMOps, structured around a full example project.
