LangSmith (under the umbrella of the company LangChain) is a platform designed to enhance the development and debugging of applications that use large language models (LLMs). It provides tools for testing, evaluating, and fine-tuning LLM-powered applications, making it easier for developers to monitor and improve the performance of these models. LangSmith is particularly useful for developers working with complex language-based applications who need a reliable environment for refining and optimizing their projects.
