Fine-tuning or RAG in 2026: LoRA, QLoRA, Distillation, and a Decision Framework

“Fine-tuning or RAG?” is a false dilemma. The 2026 sequence: Prompt → RAG → Fine-tune → Distill. LoRA/QLoRA, small language models, distillation, and the KVKK-sensitive self-host decision.

What Is LoRA? A Guide to Parameter-Efficient Fine-Tuning

What is LoRA? LoRA (Low-Rank Adaptation) is a parameter-efficient fine-tuning method that adapts a large language model by adding small, trainable matrices next to its frozen weights instead of changing all of them. This guide: a clear definition, how LoRA works, QLoRA and variants, the adapter idea, fine-tuning cost, comparison with full fine-tuning, and FAQs.

What Is Fine-Tuning?

What is fine-tuning? Fine-tuning is the method of retraining a pre-trained AI model on a smaller, task-specific dataset to adapt it to a particular behavior, tone, or domain. This guide: a clear definition, how fine-tuning works, types like SFT and LoRA, preparing training data, the difference from RAG, sector examples, data protection, limits, and FAQs.
