The proliferation of ChatGPT entry points. The race to some sort of singularity?
Foreseeably, the next step in AI integration will happen on an OS level.
In the mean time, your app will always run an inferior version compared to whatever Microsoft's sells. If having ChatGPT is your sales point, you have no sales point. You only have a very volatile, very expensive ticking time bomb dependency.
On top of that, you corner yourself into dishonesty if you sell ChatGPT as your own AI. It's bullshit and you know it.
