Why Small Models + RAG is Often Better than Large Models Alone
Explore why combining highly optimized small models with a robust knowledge base is a winning strategy for enterprise AI.
Many organizations default to using the largest possible model, but this is often overkill. A strategy of "Small Models + RAG" often provides better accuracy, lower costs, and faster response times.
Focus on Retrieval, Not Memorization
Large models "memorize" facts during training, but that knowledge quickly becomes outdated. By using a small, highly intelligent model (like Llama 3 8B) and providing it with the exact information it needs via a RAG pipeline, you ensure that the AI is always using fresh, private, and accurate data. The small model only needs enough "reasoning" power to synthesize the provided context.
Lowering the Barrier to Entry
Small models can be hosted on cheaper hardware or even on-device. Combined with a well-indexed vector database, they can provide specialized answers that rival a giant model but at a fraction of the operational complexity. This approach allows enterprises to deploy "vertical" AI assistants that are deeply knowledgeable about their specific industry without the massive overhead of a flagship model.
