The Impact of Generative AI on Collaborative Open-Source Software Development: Evidence from GitHub Copilot
GitHub Copilot raised OSS project code contributions by 5.9%, but coordination time rose 8%.
Summary
Using GitHub's proprietary Copilot usage data merged with public open-source project data, Song, Agarwal, and Wen find project-level code contributions rose 5.9%, developer participation rose 3.4%, and individual contributions rose 2.1% after Copilot adoption, though coordination time rose 8% due to more code discussion, with peripheral developers facing a worse tradeoff than core ones.
Editor's opinion
Real productivity finding but too narrow/operational (OSS coordination mechanics), not a firm-strategy insight.
