This repository provides the LangSmith SDKs for Python and JavaScript, enabling users to debug, evaluate, and monitor language models and intelligent agents. It offers native integration with the LangChain framework and is designed for developers working with LLM applications.

How It Works

The SDKs facilitate interaction with the LangSmith platform, a service for LLM observability. They allow users to trace and log LLM calls, agent actions, and intermediate steps, providing a detailed view of application execution. This approach aids in identifying issues, optimizing performance, and understanding model behavior.

Quick Start & Requirements

• Python: pip install -U langsmith
• JavaScript/TypeScript: yarn add langsmith
• Environment Variables: LANGSMITH_TRACING=true and LANGSMITH_API_KEY=ls_... are required.
• Prerequisites: Python 3.x or Node.js/npm/yarn.
• Documentation: LangSmith Documentation

Highlighted Details

• Provides wrappers for popular LLM libraries like OpenAI.
• Enables detailed tracing of LLM application execution.
• Supports both Python and JavaScript/TypeScript environments.
• Integrates natively with the LangChain framework.
