I deployed the manage Pig agent on LangGraph and it's been smooth sailing!


You can't build AI agents without monitoring. Metadata filtering is strong.

As a custom LLM-based dev company our team use LangChain suite including LangSmith and LangServe, this is a great framework that allows us to deliver LLM-based software fast and easy.
I think it's a great and must-have technology to utilize in your next LLM-based software project 💯

I've loved using LangSmith! It's efficient and user-friendly, making it a joy to work with. The platform's comprehensive visibility into the chain sequence of calls simplifies debugging and enhances the development process.

Bit rough around the edges but provides good abstractions to making requests with LLMs. Langgraph is a super handy update.
