Large language models (LLMs) like Llama 2 and techniques like RAG (Retrieval-Augmented Generation) are essential for generating truthful, factual, and useful information in various applications. However, context limitations affect the effectiveness of in-context learning. Fine-tuning is introduced as a solution to enhance model performance by training LLMs with specific data for tasks like information retrieval and generation. The talk also presents Raft, a method that improves fine-tuning by leveraging retrieval capabilities, ensuring responses are accurate and grounded in relevant documents. Practical examples highlight challenges and benefits in deploying these models effectively.
