SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

LLM applications often lack end-to-end visibility, making it hard to measure latency, cost, and quality. Langfuse provides structured tracing, observability, and evaluation to monitor and improve AI workflows.

Core Features & Use Cases

  • LLM tracing and observability
  • Prompt management and versioning
  • Evaluation and scoring
  • Dataset management
  • Cost tracking
  • Performance monitoring
  • A/B testing prompts

Quick Start

Start by enabling Langfuse tracing in your application and connecting to your Langfuse account to begin instrumenting LLM calls.

Frequently Asked Questions about langfuse

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add LLM tracing and observability to my production LangChain pipelines?▼

LLM tracing is applied to production LangChain pipelines by instrumenting LLM calls to track latency, cost, and quality. This provides structured observability to monitor and improve AI workflows end-to-end.

What is LLM observability and when do I need it for my AI workflows?▼

LLM observability provides end-to-end visibility into AI workflows by measuring latency, cost, and quality. You need it when your LLM applications lack structured tracing and performance monitoring.

Do I need a specific environment to instrument LLM calls for cost and latency tracking?▼

You need a Python or TypeScript environment, a Langfuse account, and LLM API keys. These prerequisites enable you to connect your application and begin tracing LLM calls in production.

Can I use prompt management and A/B testing to optimize LLM pipelines?▼

Prompt management and A/B testing are supported to help optimize LLM pipelines. You can manage prompt versions and compare performance to improve your application's quality and cost efficiency.

Does this LLM tracing approach work with OpenAI pipelines and other frameworks?▼

Yes, LLM tracing works with production OpenAI pipelines and other LLM frameworks. It instruments your LLM calls to track latency, cost, and quality across different environments.

How do I manage datasets and evaluation scoring for my LLM applications?▼

Dataset management and evaluation scoring are handled directly within the observability workflow. This allows you to evaluate and score your LLM applications to monitor and improve quality.
