Do you have an old Apple device?
Do you want to have conversations with OpenAI’s model on it?
Do you keep it from updating that you can not install the official ChatGPT App?
Or do you ever want to text to a model then receive both text and audio responses?

Then you have come to the right place. I hereby present you a simple python script to fulfill all your wishes above.

You can access GPT model on iOS 14 or even lower version. Just bring your own OpenAI API key, and you can contact OpenAI Realtime API in Python using Pythonista App.


Preparation

Apple Mobile Device
Pythonista App Version 3.4
OpenAI Developer Platform Credit and API Key
Network Where OpenAI Won’t Refuse to Respond

Please create a script file with following content. Then tap the run button in Pythonista. You will see two warnings in the console.

           f'websockets pydub'.
  split(' '))
)

This script will install pip in your Pythonista environment. Then it will call pip to install websockets and pydub module. The module websockets is used to communicate with OpenAI Realtime API. And pydub module is used to convert base64 encoded audio to raw audio.

Enjoy your conversation with GPT4o! Remember to insert your own OpenAI API key in the script.

Each time you hear a response. The corresponding audio file will be saved in the same directory where you save this script. The file name will be response.wav. It will change when new response appears, so save it elsewhere if you need it. Also please note that the audio will start playing only when the text response is completely shown up.
