Langfuse LLM Observability

关于

Langfuse is an open-source observability platform specifically designed for the LLM lifecycle. This skill enables developers to instrument LLM applications with detailed tracing and spans, manage complex prompt versions, and implement robust evaluation metrics for quality and cost. Whether you are using LangChain, OpenAI, or LlamaIndex, this skill provides the architectural guidance needed to move LLM projects from experimental scripts to production-ready systems with clear insights into latency, cost, and output quality.

主要功能

• End-to-end tracing and observability for LLM chains and agents
