RAG Optimization: Query Rewriting, Hybrid Search, and Re-ranking

Introduction: Retrieval-Augmented Generation (RAG) grounds LLM responses in factual data, but naive implementations often retrieve irrelevant content or miss important information. Optimizing RAG requires attention to every stage: query understanding, retrieval strategies, re-ranking, and context integration. This guide covers practical optimization techniques: query rewriting and expansion, hybrid search combining dense and sparse retrieval, re-ranking with […]

LLM Routing and Model Selection: Optimizing Cost and Quality in Production

Introduction: Not every query needs GPT-4. Routing simple questions to cheaper, faster models while reserving expensive models for complex tasks can cut costs by 70% or more without sacrificing quality. Smart LLM routing is the difference between a $10,000/month AI bill and a $3,000 one. This guide covers implementing intelligent model selection: classifying query complexity, […]

Semantic Caching for LLM Applications: Cut Costs and Latency by 50%

Introduction: LLM API calls are expensive and slow. A single GPT-4 request can cost cents and take seconds—multiply that by thousands of users asking similar questions, and costs spiral quickly. Semantic caching solves this by recognizing that “What’s the weather in NYC?” and “Tell me NYC weather” are essentially the same query. Instead of exact […]
