Trace with OpenAI Agents SDK

The OpenAI Agents SDK allows you to build agentic applications powered by OpenAI’s models.

Learn how to trace your LLM applications using the OpenAI Agents SDK with LangSmith.

Installation

Requires Python SDK version langsmith>=0.3.15.

Install LangSmith with OpenAI Agents support:

pip

pip install "langsmith[openai-agents]"

This will install both the LangSmith library and the OpenAI Agents SDK.

Quick Start

You can integrate LangSmith tracing with the OpenAI Agents SDK by using the OpenAIAgentsTracingProcessor class.

import asyncio
from agents import Agent, Runner, set_trace_processors
from langsmith.wrappers import OpenAIAgentsTracingProcessor

async def main():
    agent = Agent(
        name="Captain Obvious",
        instructions="You are Captain Obvious, the world's most literal technical support agent.",
    )

    question = "Why is my code failing when I try to divide by zero? I keep getting this error message."
    result = await Runner.run(agent, question)
    print(result.final_output)

if __name__ == "__main__":
    set_trace_processors([OpenAIAgentsTracingProcessor()])
    asyncio.run(main())

The agent’s execution flow, including all spans and their details, will be logged to LangSmith.
