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

I've been using LangSmith for a couple of months at our startup and it's been incredibly useful for running ongoing LLM evaluations and for evaluating new features. The Python SDK is handy and we've automated LangSmith evals as part of CI/CD on GitHub to spot regressions. My main struggle with LangSmith has been that the UI can be tricky to work with for larger datasets or datasets with a large experiment history. I would also love for the filters to be persisted in the URL. That way I can send a filtered set of failing examples to someone without having to provide instructions for how to reconstruct it.

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.

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 💯

Great !!! Congrats @hwchase17 for the launch of LangSmith platform. LangChain is awesome. It helps me build my LLM-based products. I'll give LangSmith platform a try to monitor my apps in production.

We started building Ting without LangSmith and we were flying blind. Diagnosing issues downstream felt like guesswork. Since bringing LangSmith in, we’ve been able to trace problems through the entire prompt path and actually understand what’s going on. We’re still evolving how we use it, but even early on it’s helped us move faster and get closer to that “this feels good” moment.

We absolutely could not build this product with LangSmith for traces, datasets, annotation queues, and evals. We've become big power users! I use to build AI apps before nice tracing tools like this existed and it's like night and day having a tool like this. We considered Langfuse, but I already had experience with LangSmith so for speed purposes we went with LangSmith.

LangSmith’s real-time analytics and versioning keep our AI agents rock-solid -- so everything just works better.
