A large-scale study across 700 firms reveals that while AI coding agents significantly increase code generation volume, they fail to boost overall software output or reduce employment. The primary bottleneck is human code review, where efficiency gains in the writing phase are entirely absorbed by downstream verification and correction costs.

Study Finds AI Coding Agents Boost Code Volume But Not Software Output Due to Review Bottlenecks
- AI coding agents accelerate the writing phase but do not significantly increase overall software delivery speed or volume.
- Human code review has emerged as the critical bottleneck, absorbing upstream time savings through downstream verification costs.
- Empirical data from over 700 firms shows no evidence that adopting AI leads to reduced employment in software development.
