Native macOS app using GPT-Codex-5.3

Unproofread notes

The new GPT-Codex-5.3 model was released only a few days ago, and I'm already seeing people build cool applications by using the model. For example, Max built a native app for Google Messages on macOS, and this looks stunning. Just look at the screenshot Max shared:

It's an open-source app and he's still pushing changes to it. The app, currently, can:

  • pair with your Android phone
  • syncs Google Messages conversations in real-time
  • sends as well as receives messages
  • push notifications work
  • supports macOS, iOS, and even visionOS

I mean, this is fascinating, and I can and should actually pursue some incomplete ideas that I have.
