Linux Foundation Study: ~25% of New Open-Source Pull Requests Are Low-Quality AI Slop
A Linux Foundation report finds that while GenAI boosts productivity, it contributes to ~25% of new open-source pull requests being low-quality 'AI slop', burdening maintainers.

The Linux Foundation published a study on October 20, 2026, examining the impact of generative AI on open-source software development. The report notes that while GenAI has the potential to cut coding time in half and increase productivity (with 71% of maintainers agreeing it lowers barriers to entry), it also introduces significant quality challenges.
The research found that approximately 25% of incoming pull requests are estimated to be low-quality 'AI slop'. Additionally, 59% of project maintainers reported growing GenAI-based contributions. This data highlights the trade-off facing the open-source community: the potential increase in contribution volume versus the rising burden of code review and declining quality.
