AI coding agent bills hit $2,000–$20,000 per developer per month
AI coding-assistant bills were documented leaping from $20–$100 to $2,000–$5,000 per developer per month, with extreme cases reaching $20,000/mo in token charges — now exceeding a developer's base salary in some firms. Reported by The Register, June 2026.
An agent ran without supervision while the operator was asleep or away, accumulating charges for hours. The fix is a time-of-day rule and a hard daily cap. time-of-day + daily total would have rejected or flagged this transaction before any money moved.
