The process of preparing documents for retrieval-augmented generation (RAG) involves breaking down large texts into smaller, manageable pieces called chunks. This 'chunking' is crucial because simply feeding an entire document to a large language model (LLM) can lead to increased costs, slower response times, and the 'lost in the middle' problem where important information is overlooked. The challenge lies in determining the optimal chunk size and splitting strategy to preserve context without making retrieval imprecise. AI
IMPACT Optimizing document chunking is key to improving the efficiency and accuracy of RAG systems, impacting how effectively LLMs can access and utilize external knowledge.
