Two weeks ago, Anthropic’s secretive AI model known as Claude Mythos was discovered because unpublished information about it was sitting in a publicly accessible database. Now the company is announcing that it is teaming with the biggest companies in the world to let that model loose to flag potential security vulnerabilities within their systems. The limited release of Mythos, dubbed Project Glasswing, includes about 40 organizations that will have access to a preview version of the model that is supposedly better than “all but the most skilled humans” at finding software vulnerabilities. Launch partners for the project include Amazon Web Services, Apple, Google, JPMorganChase, Microsoft, and NVIDIA, among others. According to Anthropic, the early returns from the collaboration have been jarring, as the company claims to have found “thousands of high-severity vulnerabilities,” including some in every major operating system and web browser. It’s unsurprising, given those apparent revelations of serious security flaws, that Anthropic believes the model “could reshape cybersecurity.” Its benchmark tests certainly seem to show that, as Mythos Preview consistently outperformed Claude Opus 4.6, including on the CyberGym test that seeks to identify how well AI agents can detect and reproduce real-world software vulnerabilities. The anecdotes support it, too. Anthropic says Mythos found a bug in the open-source operating system OpenBSD that had been there for 27 years and spotted a chain of vulnerabilities in Linux that could be used to completely hijack a machine. What’s interesting is that just weeks ago, when Mythos was first discovered (due to a very simple security slip-up, curious how that one wasn’t caught by the all-seeing machine), Anthropic was apparently positioning the model as being so powerful that it would present unprecedented cybersecurity risks. The company hasn’t totally backed off that notionâit said that it won’t make Mythos Preview available to
