Features of LangSmith
1. Debugging with Full Visibility
Unexpected results are an inherent part of software development. LangSmith empowers developers with full visibility into the entire chain sequence of calls, allowing them to identify the source of errors and surprises in real-time with surgical precision. With nested traces and prompt-level visibility, developers gain valuable insights into the functioning of their LLM applications. The real-time insights and the Playground mode further facilitate seamless debugging and error resolution.
2. Test and Evaluate with Confidence
Software engineering relies heavily on unit testing to build performant and production-ready applications. LangSmith brings the same functionality to LLM applications, enabling developers to spin up test datasets, run applications over them, and inspect results—all without leaving the platform. The dataset curation feature, along with AI-assisted evaluation, ensures rigorous testing and evaluation of LLM applications, leading to the creation of robust and reliable solutions.
3. Mission-Critical Observability
Given the stochastic nature of LLMs, understanding what’s happening with an application can be challenging. LangSmith overcomes this hurdle by providing mission-critical observability with just a few lines of code. Developers gain access to application-level usage statistics, feedback collection, and the ability to filter traces. Additionally, LangSmith allows for cost and performance measurement, ensuring LLM applications operate efficiently and effectively.
