There was a recent study posted here that showed AI introduces regressions at an alarming rate, all but one above 50%, which indicates they spend a lot of time fixing their own mistakes. You've probably seen them doing this kind of thing, making one change that breaks another, going and adjusting that thing, not realizing that's making things worse.

The study is likely "SWE-CI: Evaluating Agent Capabilities in Maintaining Codebases via Continuous Integration". Regression rate plot is figure 6.

Read the study to understand what it is measuring and how it was measured. As I understand parent's summary is fine, but you want to understand it first before repeating it to others.
