OpenAI

OpenAITools allow an Agent to interact with OpenAI models for performing audio transcription, image generation, and text-to-speech.

Prerequisites

Before using OpenAITools, ensure you have the openai library installed and your OpenAI API key configured.

Install dependencies:
uv pip install -U openai
Set your API key: Obtain your API key from OpenAI and set it as an environment variable.
export OPENAI_API_KEY=xxx
setx OPENAI_API_KEY xxx

Initialization

Import OpenAITools and add it to your Agent’s tool list.

from agno.agent import Agent
from agno.tools.openai import OpenAITools

agent = Agent(
    name="OpenAI Agent",
    tools=[OpenAITools()],
        markdown=True,
)

Usage Examples

1. Transcribing Audio

This example demonstrates an agent that transcribes an audio file.

transcription_agent.py

from pathlib import Path
from agno.agent import Agent
from agno.tools.openai import OpenAITools
from agno.utils.media import download_file

audio_url = "https://agno-public.s3.amazonaws.com/demo_data/sample_conversation.wav"

local_audio_path = Path("tmp/sample_conversation.wav")
download_file(audio_url, local_audio_path)

agent = Agent(
    name="OpenAI Transcription Agent",
    tools=[OpenAITools(transcription_model="whisper-1")],
        markdown=True,
)

agent.print_response(f"Transcribe the audio file located at '{local_audio_path}'")

2. Generating Images

This example demonstrates an agent that generates an image based on a text prompt.

image_generation_agent.py

from agno.agent import Agent
from agno.tools.openai import OpenAITools
from agno.utils.media import save_base64_data

agent = Agent(
    name="OpenAI Image Generation Agent",
    tools=[OpenAITools(image_model="dall-e-3")],
        markdown=True,
)

response = agent.run("Generate a photorealistic image of a cozy coffee shop interior")

if response.images:
    save_base64_data(response.images[0].content, "tmp/coffee_shop.png")

3. Generating Speech

This example demonstrates an agent that generates speech from text.

speech_synthesis_agent.py

from agno.agent import Agent
from agno.tools.openai import OpenAITools
from agno.utils.media import save_base64_data

agent = Agent(
    name="OpenAI Speech Agent",
    tools=[OpenAITools(
        text_to_speech_model="tts-1",
        text_to_speech_voice="alloy",
        text_to_speech_format="mp3"
    )],
    markdown=True,
)

response = agent.run("Generate audio for the text: 'Hello, this is a synthesized voice example.'")
if response and response.audio:
    save_base64_data(response.audio[0].base64_audio, "tmp/hello.mp3")

Customization

You can customize the underlying OpenAI models used for transcription, image generation, and TTS:

OpenAITools(
    transcription_model="whisper-1",
    image_model="dall-e-3",
    text_to_speech_model="tts-1-hd",
    text_to_speech_voice="nova",
    text_to_speech_format="wav"
)
