Evals are a vital part of bringing LLM apps to production. To make it easier to get started, we launched a new OSS repo: OpenEvals!

OpenEvals contains prebuilt evaluators that help you quickly add evals to your app, whether it's built with LangChain, LangGraph, or neither. They encapsulate what we've seen as emerging best practices in the industry.

Try it out in Python or JS - we welcome any feedback or contributions!

Read more about OpenEvals in our blog and see it in action in this video.
