AI-generated code: Looks fine until review reveals issues

Software teams have spent the past year sorting through a rising volume of pull requests generated with help from AI coding tools. New research puts numbers behind what many reviewers have been seeing during work. The research comes from CodeRabbit and examines how AI co-authored code compares with human written code across hundreds of open source projects. The findings track issue volume, severity, and the kinds of problems that appear most often.
