Field notes

Notes on the token economy.

Practical writing on AI token economics, prompt cost discipline, and the small habits that separate teams who spend $400 / month from teams who spend $4,000 for the same output.

Tokens are the new productivity metric.

Nvidia's CEO told the All-In podcast he'd be "deeply alarmed" if a $500,000 engineer didn't consume at least $250,000 worth of AI tokens. Read past the eye-popping number and there's a bigger shift here: token consumption is becoming the new visibility metric for engineering work.

Why tracking tokens matters.

Your AI invoice tells you the total. It doesn't tell you which prompts cost $4 each, which dev burned $80 in a single Cursor session, or that 30% of your monthly bill is the same five prompts being retried. Visibility comes first — optimization second.
