Seven posts, seven production systems. This final installment assembles every piece — distributed tracing, metrics, evaluation, prompt versioning, RAG observability, and cost governance — into one reference architecture with a phased implementation checklist you can start using this week.

Cost Governance and FinOps for LLM Workloads
In 2026, inference accounts for 85% of enterprise AI budgets — and agentic loops mean costs can spiral quadratically from a single runaway task. This post builds a complete LLM cost governance system: per-feature attribution, tenant budgets with hard limits, spend anomaly detection, and the optimization levers that cut bills without touching quality.
RAG Pipeline Observability: Tracing Retrieval, Chunking, and Embedding Quality
A RAG pipeline has five distinct places it can fail before the LLM ever sees your context. This post instruments every stage — query embedding, vector search, document ranking, context assembly, and generation — with OpenTelemetry spans and quality metrics, in Node.js, Python, and C#.
Prompt Management and Versioning: Treating Prompts as Production Code
Prompt changes are production changes. A wording edit at 3pm on a Friday can silently degrade thousands of responses with no error signal. This post builds a production-grade prompt management system with versioning, A/B testing, quality gates, and rollback in Node.js, Python, and C#.
Evaluating LLM Output Quality in Production: LLM-as-Judge and Human Feedback Loops
Tracing and metrics tell you when something is slow or expensive. Evaluation tells you when something is wrong. This post builds a production-grade LLM-as-judge pipeline in Node.js, Python, and C# — with a human feedback loop that catches what automation misses.
LLM Metrics That Actually Matter: Latency, Cost, Hallucination Rate, and Drift
Uptime and error rate are not enough. This post covers the metrics that actually reveal whether your LLM is working correctly in production — time-to-first-token, cost per request, hallucination rate indicators, output drift, and how to build dashboards that catch silent failures before users do.
Distributed Tracing for LLM Applications with OpenTelemetry
You cannot fix what you cannot see. This post walks through instrumenting a full LLM pipeline with OpenTelemetry in Node.js, Python, and C# — capturing every span from user request through retrieval, model call, tool execution, and response.
Why LLMOps Is Not MLOps: The New Operational Reality for AI Teams
Most teams try to apply their existing MLOps practices to LLMs and hit a wall fast. This post breaks down exactly why LLMOps is a different discipline, where the gaps are, and what the new operational stack looks like in production.
