AI code reviewers show wild performance gaps in bug detection

By PulseAugur Editorial · [1 sources] ·

A user has developed a tool to benchmark AI code reviewers against real-world bugs and CVEs. The tool feeds known vulnerabilities and their fixes to various AI models, scoring their ability to detect them. Initial results show significant performance gaps between models, with some consistently identifying specific bug classes while others miss them or hallucinate issues. Notably, the latest Claude model reportedly refused to review security code. AI

IMPACT Highlights significant disparities in AI code review capabilities, impacting software development security and efficiency.

    I've been benchmarking AI code reviewers on real bugs and the gap between models is wild

    <!-- SC_OFF --><div class="md"><p>I have been building a thing that feeds real known bugs, actual CVEs with the real fix to different AI models and scores whether they catch them. a few things surprised me, some models catch a whole bug class every time, others miss it every time…
