LangFuse is an open-source LLM observability and evaluation platform that helps AI engineers trace, monitor, debug, evaluate, and optimize production-grade AI, RAG, and agentic applications. Large Language Models (LLMs) have transformed the way modern applications are built, but deploying AI systems into production introduces new challenges around visibility, debugging, monitoring, evaluation, cost control, and reliability. Traditional monitoring tools are not designed to understand prompts, model responses, retrieval pipelines, agent workflows, or AI-specific performance metrics.
This course provides a comprehensive, hands-on introduction to LangFuse, one of the leading open-source platforms for LLM observability, tracing, prompt management, evaluation, and production monitoring. You will learn how to instrument AI applications, capture traces, analyze model behavior, monitor token usage and costs, evaluate response quality, and build reliable AI systems that can be confidently deployed at scale.
