Helicone integrations | LangChain 简体中文

This page covers how to use the Helicone ecosystem within LangChain.

What is helicone?

Helicone is an open-source observability platform that proxies your OpenAI traffic and provides you key insights into your spend, latency and usage.

Quick start

With your LangChain environment you can just add the following parameter.

export OPENAI_API_BASE="https://oai.hconeai.com/v1"

Now head over to helicone.ai to create your account, and add your OpenAI API key within our dashboard to view your logs.
