Agent Extra Metrics

This example demonstrates how to collect special token metrics including audio, cached, and reasoning tokens. It shows different types of advanced metrics available when working with various OpenAI models.

Code

agent_extra_metrics.py

import requests
from agno.agent import Agent
from agno.media import Audio
from agno.models.openai import OpenAIResponses
from agno.utils.pprint import pprint_run_response

# Fetch the audio file and convert it to a base64 encoded string
url = "https://openaiassets.blob.core.windows.net/$web/API/docs/audio/alloy.wav"
response = requests.get(url)
response.raise_for_status()
wav_data = response.content

agent = Agent(
    model=OpenAIResponses(
        id="gpt-5.2",
        modalities=["text", "audio"],
        audio={"voice": "sage", "format": "wav"},
    ),
    markdown=True,
)
run_response = agent.run(
    "What's in these recording?",
    audio=[Audio(content=wav_data, format="wav")],
)
pprint_run_response(run_response)
# Showing input audio, output audio and total audio tokens metrics
print(f"Input audio tokens: {run_response.metrics.audio_input_tokens}")
print(f"Output audio tokens: {run_response.metrics.audio_output_tokens}")
print(f"Audio tokens: {run_response.metrics.audio_total_tokens}")

agent = Agent(
    model=OpenAIResponses(id="gpt-5.2"),
    markdown=True,
    telemetry=False,
)
run_response = agent.run(
    "Solve the trolley problem. Evaluate multiple ethical frameworks. Include an ASCII diagram of your solution.",
    stream=False,
)
pprint_run_response(run_response)
# Showing reasoning tokens metrics
print(f"Reasoning tokens: {run_response.metrics.reasoning_tokens}")

agent = Agent(model=OpenAIResponses(id="gpt-5.2"), markdown=True, telemetry=False)
agent.run("Share a 2 sentence horror story" * 150)
run_response = agent.run("Share a 2 sentence horror story" * 150)
# Showing cached tokens metrics
print(f"Cached tokens: {run_response.metrics.cache_read_tokens}")

Usage

1. Create a Python file

   Create agent_extra_metrics.py with the code above.

2. Set up your virtual environment

   Mac

   uv venv --python 3.12
   source .venv/bin/activate
   

   uv venv --python 3.12
   .venv\Scripts\activate
   
3. Install dependencies

   uv pip install -U agno openai requests
   
4. Export your OpenAI API key

   Mac/Linux

   export OPENAI_API_KEY="your_openai_api_key_here"
   

   $Env:OPENAI_API_KEY="your_openai_api_key_here"
   
5. Run Agent

   python agent_extra_metrics.py
