Ultimate LLMOps with Langfuse: Instrument, Evaluate, and Operate Production-Grade LLM Applications with Langfuse (English Edition)

Master Langfuse and Build LLM Systems That Perform in Production Key Features ● Get a free one-month digital subscription to www.avaskillshelf.com ● Covers Production LLM observability like traces, costs, latency, and drift detection. ● Structured prompt management with versioning, testing, and safe deployment workflows. ● Continuous LLM evaluation using automated scoring, feedback, and regression testing. Book Description Ultimate LLMOps with Langfuse gives you the observability, evaluation, and operational discipline to run LLM systems you can actually trust in production, replacing intuition-driven development with measurable, data-driven engineering practice. You begin with LLM monitoring fundamentals, including tracing, drift detection, and bias awareness, then move into Langfuse's core capabilities, covering instrumentation, observability dashboards, prompt management, and structured evaluation. The book addresses automated scoring, human feedback workflows, cost and latency tracking, and production metrics, grounding every concept in concrete examples and real system architectures. The final section delivers end-to-end playbooks for agentic workflows, RAG pipelines, security guardrails, and LLM governance. By the end of the book, you will be able to instrument, evaluate, and operate production LLM applications with full visibility, debug faster, improve quality continuously, and ship AI features with confidence. What you will learn ● Instrument LLM applications with end-to-end tracing and observability pipelines. ● Detects model drift, bias, and quality regressions in production systems. ● Manage, version, and deploy prompts across production AI applications. ● Evaluate LLM outputs using automated scoring and human feedback workflows. ● Build dashboards tracking cost, latency, safety, and production performance. ● Apply guardrails and governance frameworks for secure LLM deployments. Who is this book for? This book is tailored for AI engineers, ML practitioners, backend developers, and platform engineers who build or operate LLM-powered applications in production. Basic Python experience and familiarity with REST APIs and JSON are assumed; however, no prior Langfuse experience is required. Table of Contents 1.
