Anthropic’s Project Glasswing Update

Anthropic's Project Glasswing, launched in April to help companies identify software vulnerabilities using AI, has produced questionable results despite positive media coverage. While the project claims to find numerous vulnerabilities, very few have actually been patched, and Anthropic's refusal to release detailed data raises transparency concerns about the initiative's actual effectiveness.

In April, Anthropic initated Project Glasswing . The idea was to let companies use their new model to find and fix vulnerabilities in their own software. It was a fantastic PR move, and so many press outlets have uncritically parroted Anthropic’s claims that it’s now common wisdom that Mythos is better at finding software vulnerabilities than other models.

Which is just not true . In any case, Anthropic has published a Project Glasswing status report. It’s finding a lot of vulnerabilities in software—yay!

Some of them are even dangerous. But almost none of them has been patched. It’s weird .

There’s something fishy about the data that I don’t understand. That Anthropic refuses to release details—that it just says “trust us”—is a big problem here.
