AI Boosts Developer Productivity By Moderate Margin

GitHub and Stanford-backed analyses in recent studies find AI-assisted developers see average productivity gains of roughly 30–40%, with specific experiments reporting up to 55% faster task completion and 8% more completions. Gains concentrate in low-complexity, greenfield work while mature projects show 0–40% increases and sometimes negative effects; practitioners should emphasize review, specs, and domain documentation when deploying AI tools.
