LLM Performance: Prompting, RAG, and Fine-Tuning Trade-offs Explored

This article explores the trade-offs between three primary methods for enhancing large language model performance: prompting, Retrieval-Augmented Generation (RAG), and fine-tuning. Prompting offers a quick way to guide model output but has limitations in context length and complexity. RAG improves responses by providing external data but can be slower and more complex to implement. Fine-tuning allows for deeper customization by retraining the model on specific datasets, offering the highest potential for specialized performance but requiring significant resources and expertise.
