Anthropic launches free AI security scanner for open source

The new service uses Anthropic's strongest models to find vulnerabilities, but its reports come without human review.

Anthropic, as reported by The Verge, has launched OSS Scanner, a free service that offers open-source projects periodic security scans by the company's most capable AI models. The trade-off: the results are entirely machine-generated with no human oversight.

Projects that opt in get scanned by Anthropic's strongest models, including Claude Mythos. The company says this enables faster and more frequent scanning. But it also acknowledges the reports may be incorrect or invalid, since no one is checking the AI's work.

This isn't the first attempt at AI-powered bug hunting. AI tools have uncovered serious flaws like the "Copy Fail" bug that affected nearly every Linux distribution in May. At the same time, open-source maintainers are drowning in AI-generated bug reports, as Linus Torvalds and even Google have noted.

What does OSS Scanner do that a human security researcher doesn't? It's faster and free. But it's also error-prone and unverified. If you're an open-source maintainer, you might get more noise than signal. If you're not, you can skip this entirely.
