OpenAI - Pydantic Logfire Documentation

We support instrumenting both the standard OpenAI SDK package and OpenAI "agents" framework.

Logfire supports instrumenting calls to OpenAI with the logfire.instrument_openai() method, for example:

import openai
import logfire

client = openai.Client()

logfire.configure()
logfire.instrument_openai()  # instrument all OpenAI clients globally
# or logfire.instrument_openai(client) to instrument a specific client instance

response = client.chat.completions.create(
    model='gpt-4',
    messages=[
        {'role': 'system', 'content': 'You are a helpful assistant.'},
        {'role': 'user', 'content': 'Please write me a limerick about Python logging.'},
    ],
)
print(response.choices[0].message)

With that you get:

• a span around the call to OpenAI which records duration and captures any exceptions that might occur
• Human-readable display of the conversation with the agent
• details of the response, including the number of tokens used

The following OpenAI methods are covered:

• client.chat.completions.create — with and without stream=True
• client.completions.create — with and without stream=True
• client.embeddings.create
• client.images.generate
• client.responses.create

All methods are covered with both openai.Client and openai.AsyncClient.

For example, here's instrumentation of an image generation call:

import openai
import logfire

async def main():
    client = openai.AsyncClient()
    logfire.configure()
    logfire.instrument_openai(client)

    response = await client.images.generate(
        prompt='Image of R2D2 running through a desert in the style of cyberpunk.',
        model='dall-e-3',
    )
    url = response.data[0].url
    import webbrowser
    webbrowser.open(url)

if __name__ == '__main__':
    import asyncio
    asyncio.run(main())

Gives:

When instrumenting streaming responses, Logfire creates two spans — one around the initial request and one around the streamed response.

Here we also use Rich's Live and Markdown types to render the response in the terminal in real-time.

import openai
import logfire
from rich.console import Console
from rich.live import Live
from rich.markdown import Markdown

client = openai.AsyncClient()
logfire.configure()
logfire.instrument_openai(client)

async def main():
    console = Console()
    with logfire.span('Asking OpenAI to write some code'):
        response = await client.chat.completions.create(
            model='gpt-4',
            messages=[
                {'role': 'system', 'content': 'Reply in markdown one.'},
                {'role': 'user', 'content': 'Write Python to show a tree of files 🤞.'},
            ],
            stream=True
        )
        content = ''
        with Live('', refresh_per_second=15, console=console) as live:
            async for chunk in response:
                if chunk.choices[0].delta.content is not None:
                    content += chunk.choices[0].delta.content
                    live.update(Markdown(content))

if __name__ == '__main__':
    import asyncio
    asyncio.run(main())

Shows up like this in Logfire:

We also support instrumenting the OpenAI "agents" framework.

import logfire
from agents import Agent, Runner

logfire.configure()
logfire.instrument_openai_agents()

agent = Agent(name="Assistant", instructions="You are a helpful assistant")

result = Runner.run_sync(agent, "Write a haiku about recursion in programming.")
print(result.final_output)

For more information, see the instrument_openai_agents() API reference.

Which shows up like this in Logfire:

In this example we add a function tool to the agents:

from typing_extensions import TypedDict

import logfire
from httpx import AsyncClient
from agents import RunContextWrapper, Agent, function_tool, Runner

logfire.configure()
logfire.instrument_openai_agents()


class Location(TypedDict):
    lat: float
    long: float


@function_tool
async def fetch_weather(ctx: RunContextWrapper[AsyncClient], location: Location) -> str:
    """Fetch the weather for a given location.

    Args:
        ctx: Run context object.
        location: The location to fetch the weather for.
    """
    r = await ctx.context.get('https://httpbin.org/get', params=location)
    return 'sunny' if r.status_code == 200 else 'rainy'


agent = Agent(name='weather agent', tools=[fetch_weather])


async def main():
    async with AsyncClient() as client:
        logfire.instrument_httpx(client)
        result = await Runner.run(agent, 'Get the weather at lat=51 lng=0.2', context=client)
    print(result.final_output)


if __name__ == '__main__':
    import asyncio
    asyncio.run(main())

We see spans from within the function call nested within the agent spans:
