Notes on ‘AI Engineering’ (Chip Huyen) chapter 7: Finetuning

This article summarizes and analyzes Chapter 7 from Chip Huyen's 'AI Engineering' on model fine-tuning. It explains the core argument that fine-tuning is a significant investment and should be a last resort after simpler methods like prompt engineering and RAG. It covers key technical considerations like memory constraints and PEFT (e.g., LoRA), the substantial infrastructure required, and a recommended progression pathway for implementing AI solutions.
