Introduction: LLMs generate text, but applications need structured, reliable data. The gap between free-form text and validated output is where many LLM applications fail. Output validation ensures LLM responses meet your application’s requirements—correct schema, valid values, appropriate content, and consistent format. This guide covers practical validation techniques: schema validation with Pydantic, semantic validation for content… Continue reading

Introduction: Single agents hit limits—they can’t be experts at everything, they struggle with complex multi-step tasks, and they lack the ability to parallelize work. Multi-agent systems solve these problems by coordinating multiple specialized agents, each with distinct capabilities and roles. This guide covers practical multi-agent patterns: orchestrator agents that delegate and coordinate, specialist agents with… Continue reading

Introduction: Neither keyword search nor semantic search is perfect alone. Keyword search excels at exact matches and specific terms but misses semantic relationships. Semantic search understands meaning but can miss exact phrases and rare terms. Hybrid search combines both approaches, leveraging the strengths of each to deliver superior retrieval quality. This guide covers practical hybrid… Continue reading

Introduction: Tokens are the currency of LLM applications—every token costs money and consumes context window space. Efficient token usage directly impacts both cost and capability. This guide covers practical token optimization techniques: accurate token counting across different models, content compression strategies that preserve meaning, budget management for staying within limits, and prompt engineering patterns that… Continue reading

Introduction: LLM applications are notoriously difficult to debug and monitor. Unlike traditional software where inputs and outputs are deterministic, LLMs produce variable outputs that can fail in subtle ways. Observability—the ability to understand system behavior from external outputs—is essential for production LLM systems. This guide covers practical observability patterns: distributed tracing for complex LLM chains,… Continue reading

Introduction: Prompts are code—they define your application’s behavior and should be managed with the same rigor as source code. Yet many teams treat prompts as ad-hoc strings scattered throughout their codebase, making it impossible to track changes, compare versions, or systematically improve performance. This guide covers practical prompt management: version control systems for prompts, A/B… Continue reading

Introduction: Vector search finds semantically similar content, but it misses the structured relationships that make knowledge truly useful. Knowledge graphs capture entities and their relationships explicitly—who works where, what depends on what, how concepts connect. Combining knowledge graphs with LLMs creates systems that can reason over structured relationships while generating natural language responses. This guide… Continue reading

Introduction: Fine-tuning transforms general-purpose language models into specialized tools for your domain. While prompting works for many tasks, fine-tuning delivers consistent behavior, lower latency, and reduced token costs when you need the model to reliably follow specific formats, use domain terminology, or exhibit particular reasoning patterns. This guide covers practical fine-tuning strategies: preparing high-quality training… Continue reading

Introduction: Initial retrieval casts a wide net—vector search or keyword matching returns candidates that might be relevant. Reranking narrows the focus, using more expensive but accurate models to score each candidate against the query. Cross-encoders process query-document pairs together, capturing fine-grained semantic relationships that bi-encoders miss. This two-stage approach balances efficiency with accuracy: fast retrieval… Continue reading

Introduction: Long contexts contain valuable information, but they also contain noise, redundancy, and irrelevant details that consume tokens and dilute model attention. Context distillation extracts the essential information from lengthy documents, conversations, or retrieved passages, producing compact representations that preserve what matters while discarding what doesn’t. This technique is crucial for RAG systems processing multiple… Continue reading
