Introduction: LLM API costs can spiral quickly—a chatbot handling 10,000 daily users at $0.01 per conversation costs $3,000 monthly. Production systems need cost optimization without sacrificing quality. This guide covers practical strategies: semantic caching to avoid redundant calls, model routing to use cheaper models when possible, prompt compression to reduce token counts, and monitoring to […]

LLM Evaluation: Metrics, Benchmarks, and A/B Testing
Introduction: Evaluating LLM outputs is challenging because there’s often no single “correct” answer. Traditional metrics like BLEU and ROUGE fall short for open-ended generation. This guide covers modern evaluation approaches: automated metrics for specific tasks, LLM-as-judge for quality assessment, human evaluation frameworks, A/B testing in production, and building comprehensive evaluation pipelines. These techniques help you […]

Introduction: You can’t improve what you can’t measure. LLM applications are notoriously difficult to debug—prompts are opaque, responses are non-deterministic, and failures often manifest as subtle quality degradation rather than crashes. Observability gives you visibility into every LLM call: what prompts were sent, what responses came back, how long it took, how much it cost, […]
Read more →Hybrid Search Implementation: Combining Vector and Keyword Retrieval
Introduction: Hybrid search combines the best of both worlds: the semantic understanding of vector search with the precision of keyword matching. Pure vector search excels at finding conceptually similar content but can miss exact matches; pure keyword search finds exact terms but misses semantic relationships. Hybrid search fuses these approaches, using vector similarity for semantic […]

Introduction: GitHub Copilot Chat, released in late 2023, represents a paradigm shift in AI-assisted development by bringing conversational AI directly into the IDE. Unlike the original Copilot’s inline suggestions, Copilot Chat enables developers to ask questions, request explanations, generate tests, and refactor code through natural language dialogue. After integrating Copilot Chat into my daily workflow […]
Read more →LLM Fallback Strategies: Multi-Provider Failover Architecture (Part 1 of 2)
Introduction: Production LLM applications must handle failures gracefully—API outages, rate limits, timeouts, and degraded responses are inevitable. Fallback strategies ensure your application continues serving users when the primary model fails. This guide covers practical fallback patterns: multi-provider failover, graceful degradation, circuit breakers, retry policies, and health monitoring. The goal is building resilient systems that maintain […]
