A LangSmith SDK is a LLM App framework SDK designed for LangSmith framework.

  • Context:
    • It can (typically) support both Python and JavaScript/TypeScript environments for multi-language compatibility.
    • It can (typically) be used to locally develop, debug, and test LLM-based applications.
    • It can (often) provide callbacks for handling LLM interactions and track these interactions in the LangSmith platform for real-time evaluation and monitoring.
    • It can (often) be used in conjunction with LangSmith Core for full deployment scenarios, where both local and production systems interact seamlessly.
    • ...
    • It can enable implementing, tracing, and debugging LLM workflow locally while interacting with the LangSmith framework's full-stack capabilities.
    • It can integrate seamlessly with the LangSmith Platform, allowing developers to log traces, manage prompts, and monitor performance.
    • It can offer functionalities such as trace logging, prompt versioning, and dataset management that are extended from local development to production environments.
    • It can be used by developers to streamline the transition from local LLM development to cloud-based deployment, leveraging LangSmith's infrastructure for scaling and production use cases.
    • It can enable the use of advanced debugging tools and asynchronous trace handling, connecting local applications to the LangSmith platform’s monitoring and observability tools.
    • It can integrate with popular LLM providers like OpenAI and Hugging Face for API-driven LLM development and deployment.
    • ...
  • Example(s):
    • LangSmith SDK, v0.1.116: The latest version of the LangSmith SDK for Python, providing updates to trace logging, error handling, and API integration with the LangSmith platform.
