MWITA-WO-2026-007 · Evidence A · P1
Three randomized enterprise experiments covering 4,867 developers found a pooled 26.08% increase in completed tasks with an AI coding assistant, while individual experiments were noisy and less-experienced developers adopted more and gained more.
Counterevidence & uncertainty
Tool generation and enterprise contexts differ from METR's mature open-source tasks; pooled estimate masks noise.
What would change the reading
Update with task-quality, defect, maintenance and later-tool replications.
