More FAQs in When to Fine-Tune an LLM vs When to Use RAG
Yes, you can fine-tune a model to output a specific style, and then use RAG to feed it real-time search context.
Parameter-Efficient Fine-Tuning techniques that only train a tiny fraction of the model's weights (adapter), reducing training costs.
No, RAG only provides context. Fine-tuning updates the model's behavioral patterns.
