METR introduces a new metric to calculate exactly when AI agents become more expensive than humans
METR just put a price tag on AI agent economics. And the early numbers are sobering.

Why it matters
As AI agents move from research to deployment, understanding their true cost-of-ownership relative to human labor is becoming critical for enterprise decision-making. METR's 'expenditure horizon' metric attempts to quantify the breakeven point—but early benchmarks suggest we're not there yet.

Publisher excerpt: METR's new metric, the "expenditure horizon," puts a dollar figure on how cost-effective AI agents are at solving problems. Early results on the NanoGPT speedrun are underwhelming, the metric has blind spots, and the newest generation of models could change the picture.
