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).

​
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)
