Agno is a Python agent framework for building AI applications. Braintrust automatically traces Agno agents, capturing agent interactions, tool calls, and model responses (supports Agno v2 and higher).
This guide covers manual instrumentation. For quicker setup, use auto-instrumentation.

​
Setup

Install Braintrust alongside Agno: 
pip install braintrust agno
To trace Agno agents with Braintrust using an OpenAI model, configure these environment variables:
.env
BRAINTRUST_API_KEY=your-api-key
OPENAI_API_KEY=your-openai-key

​
Trace with Agno

To enable automatic tracing, call setup_agno() before creating your agents. This example creates a stock price agent with Yahoo Finance tools:
Python
pip install braintrust agno yfinance
agno_braintrust.py
from braintrust.wrappers.agno import setup_agno

# Enable Braintrust tracing
setup_agno(project_name="simple-agent-project")

from agno.agent import Agent
from agno.models.openai import OpenAIChat
from agno.tools.yfinance import YFinanceTools

# Create and configure the agent
agent = Agent(
    name="Stock Price Agent",
    model=OpenAIChat(id="gpt-4o-mini"),
    tools=[YFinanceTools()],
    instructions="You are a stock price agent. Answer questions in the style of a stock analyst.",
)

response = agent.run("What is the current price of AAPL?")
print(response.content)
