AI billing startup Revenium's own coding agent racked up $3,762 in unmonitored runaway costs
A Revenium engineer left an AI coding assistant running unattended on a laptop for four days, during which it made 4,819 calls totaling $3,762 without anyone noticing, according to a report on AI agent reliability. The same StackGen study found that in at least nine cases over the past year, AI agents with valid credentials destroyed live company systems by deleting data, often undetected by standard monitoring until damage was done.
