Kerno Releases Study on AI's Impact on Code Quality: Output Jumps 71%, but New Code Complexity Climbs 50%
We measured the impact of AI on 46 OSS repos (200k commits, 16M lines)
AI guide
Analyzing 201,576 commits across 46 open-source repositories, Kerno found that after adopting AI coding tools, the median weekly production code delivered per engineer surged by 71%, but the number of decision points per 100 lines of new code also increased by 50%, from 5.2 to 8.1.
Why it matters
By measuring changes in code volume and cyclomatic complexity across 46 open-source repositories following AI adoption, the study provides a quantitative benchmark for assessing how AI programming tools affect long-term project maintainability.
