Trace with OpenAI Agents SDK

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

Installation

Install LangSmith with OpenAI Agents support:

pip install "langsmith[openai-agents]"

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

Note: This integration requires LangSmith Python SDK version 0.3.15 or higher.

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.
