OpenAI Audio Input Local File Upload

Send a local MP3 file to gpt-audio and get a text description of the audio.

OpenAI schedules gpt-audio for shutdown on January 20, 2027. It remains available until that announced date. See the provider lifecycle notice and verify audio formats and streaming support when selecting a replacement.

Run the Example

Set up your virtual environment

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

Install dependencies

uv pip install -U agno openai

Export your OpenAI API key

export OPENAI_API_KEY="your_openai_api_key_here"

Provide the audio file

Place a valid MP3 named sample.mp3 beside audio_input_local_file_upload.py, or update audio_path in your saved copy. Agno reads and base64-inlines this file in the chat request; this example does not use the OpenAI Files API. A missing path leaves the request without its audio input.

Run the example

Save the code above as audio_input_local_file_upload.py, then run:

python audio_input_local_file_upload.py
