Don’t rely on AI generated patches since they fail half the time!

DarkReading.com reported that “A study of more than 6,000 patches found that even working patches can introduce new bugs, break something else, or are open to bypass.”  The August 7, 2026 article entitled “AI-Generated Patches Fail Half the Time” (https://www.darkreading.com/application-security/ai-generated-patches-fail-half-time) included these comments:

Recent research suggests that even the latest AI systems only produce effective patches about half the time, according to a report published on Aug. 6 by identity management firm 1Password. To test their efficacy, the company's Off-By-1 research team generated 540 patches for six vulnerabilities disclosed since March using two different large language models (LLMs): OpenAI's ChatGPT-5.5 with Trusted Access for Cyber, and Anthropic's Opus 4.8 with Cyber Verification Program.

Of those 6,080 patches, only 46% of them solved the underlying vulnerability, and many introduced new vulnerabilities into the mix. Even the working patches were often "brittle," fixing only a narrow set of cases or were bypassed with a fairly easy workaround, says Keith Hoodlet, director of security research for 1Password.

"Based on our research for [AI-generated patches for flaws] that are novel or not part of the training data set for the AI labs, the patch success rate has gone negative, in terms of the outcomes," he says.

Any one surprised?
