A developer burned 2 billion tokens porting a Mac app to iPhone

A developer says they spent 2 billion tokens over a few days while porting a Mac app to iPhone, and now wants to break down where the usage went.
The post is interesting less as a model claim and more as a practical engineering signal: when AI is used heavily in app porting work, token burn can become enormous very quickly. It points to a real-world need to measure and audit agent-assisted development costs instead of assuming the workflow is cheap.
