Introduction: Retrieval Augmented Generation (RAG) has become the standard pattern for grounding LLM responses in factual, up-to-date information. But basic RAG—retrieve chunks, stuff into prompt, generate—often falls short in production. Queries get misunderstood, irrelevant chunks pollute context, and answers lack coherence. This guide covers advanced RAG patterns that address these challenges: query transformation to improve… Continue reading

Introduction: High-dimensional embeddings from models like OpenAI’s text-embedding-3-large (3072 dimensions) or Cohere’s embed-v3 (1024 dimensions) deliver excellent semantic understanding but come with costs: more storage, slower similarity computations, and higher memory usage. For many applications, you can reduce dimensions significantly while preserving most of the semantic information. This guide covers practical dimensionality reduction techniques: PCA… Continue reading

Introduction: LLM latency is the silent killer of user experience. Even the most accurate model becomes frustrating when users wait seconds for each response. The challenge is that LLM inference is inherently slow—autoregressive generation means each token depends on all previous tokens. This guide covers practical techniques for reducing perceived and actual latency: streaming responses… Continue reading

Introduction: Agentic workflows represent a paradigm shift from simple prompt-response patterns to autonomous, goal-directed AI systems. Unlike traditional LLM applications where the model responds once and stops, agentic systems can plan multi-step solutions, execute actions, observe results, and iterate until the goal is achieved. This guide covers the core patterns that make agentic systems work:… Continue reading

Introduction: Prompt engineering is the art and science of communicating effectively with large language models. Unlike traditional programming where you write explicit instructions, prompt engineering requires understanding how models interpret language, what context they need, and how to structure requests for optimal results. This guide covers the fundamental techniques that separate amateur prompts from production-quality… Continue reading

Introduction: Memory is what transforms a stateless LLM into a contextually aware assistant. Without memory, every interaction starts from scratch—the model has no knowledge of previous conversations, user preferences, or accumulated context. This guide covers the memory architectures that enable persistent, intelligent AI systems: conversation buffers for recent context, summary memory for long conversations, vector-based… Continue reading

Introduction: Function calling transforms LLMs from text generators into action-taking agents. Instead of just producing text responses, models can now decide when to call external functions, APIs, or tools to accomplish tasks. This capability enables building assistants that can search the web, query databases, send emails, execute code, and interact with any system that exposes… Continue reading

Introduction: LLM outputs are inherently unstructured—models generate text, not data structures. Yet most applications need structured data: JSON for APIs, typed objects for business logic, specific formats for downstream processing. Output parsing bridges this gap, transforming free-form text into reliable, validated data structures. This guide covers the techniques that make parsing robust: format specification in… Continue reading

Introduction: Basic RAG retrieves documents and stuffs them into context. Advanced RAG transforms retrieval into a sophisticated pipeline that dramatically improves answer quality. This guide covers the techniques that separate production RAG systems from prototypes: query rewriting to improve retrieval, hybrid search combining dense and sparse methods, cross-encoder reranking for precision, contextual compression to fit… Continue reading
