Semantic Kernel: Microsoft’s Enterprise SDK for Building AI-Powered Applications

Introduction: Semantic Kernel is Microsoft’s open-source SDK for integrating Large Language Models into applications. Originally developed to power Microsoft 365 Copilot, it has evolved into a comprehensive framework for building AI-powered applications with enterprise-grade features. Unlike other LLM frameworks that focus primarily on Python, Semantic Kernel provides first-class support for both C# and Python, making […]

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, […]

Building Production RAG Applications with LangChain: From Document Ingestion to Conversational AI

Introduction: LangChain has emerged as the dominant framework for building production Retrieval-Augmented Generation (RAG) applications, providing abstractions for document loading, text splitting, embedding, vector storage, and retrieval chains. By late 2023, LangChain reached production maturity with improved stability, better documentation, and enterprise-ready features. After deploying LangChain-based RAG systems across multiple organizations, I’ve found that its […]

LLM Observability: Cost Tracking and Quality Monitoring (Part 2 of 2)

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, […]
