RAG vs Fine-Tuning
RAG supplies external knowledge at runtime; fine-tuning changes learned behavior through additional training.
Think of it like
Think of RAG vs Fine-Tuning as changing how a trained worker behaves or how efficiently that worker can be deployed, rather than giving it a live reference book.
Real life
Organizations adapt general models using techniques such as RAG vs Fine-Tuning.
SRE lens
Use RAG for current runbooks; fine-tune only when behavior repeatedly needs adaptation.
Remember thisRAG supplies external knowledge at runtime; fine-tuning changes learned behavior through additional training.
