Fine-tuning vs RAG vs Prompting: The Decision Framework in GenAI EngineeringInterview Readiness Check
The decision matrix every AI engineer must internalise: when to fine-tune, when to RAG, when to just prompt better. Dataset requirements, cost models, latency impacts, quality ceiling analysis, distillation from frontier models, PEFT vs full fine-tune, and the interview trade-off questions around each choice..
