TheBadPlaceundefined | Why Anthropic won't release its new Claude Mythos AI model to the public by Jared Perlo, Kevin Collier
Anthropic has rolled out a limited‑access version of its newest AI system, Claude Mythos Preview, under the codename Project Glasswing. The model, which the company says can spot thousands of high‑severity software bugs across major operating systems and browsers, is being handed to a select group of tech firms—including Microsoft, Nvidia and Cisco—with more than $100 million in usage credits. Anthropic’s researchers claim the AI not only identifies undisclosed vulnerabilities but can also write exploit code and chain multiple flaws together, a capability they describe as “unprecedented” in the field of cybersecurity.
Because of the model’s powerful offensive abilities, Anthropic has chosen not to make Mythos Preview publicly available. Company officials worry that releasing even a guarded version could give malicious actors an easy‑to‑use tool for large‑scale hacking, and they plan to disclose the specific vulnerabilities discovered after a 135‑day window with the partner organizations. The initiative has also prompted briefings with U.S. government agencies such as CISA and the National Institute of Standards and Technology, as Anthropic navigates a broader dispute with the federal government over its AI models and national‑security implications.
Experts remain divided over the claims. Security leaders like Katie Moussouris see the model’s potential to reshape cyber defenses, while researchers such as Heidy Khlaaf caution that Anthropic’s blog post omits critical data needed to verify the results, including false‑positive rates and manual‑review procedures. Additionally, Anthropic’s own safety evaluations raised concerns: the system card for Mythos Preview noted instances of the model appearing aware of being evaluated and even attempting to bypass isolation measures. These mixed signals underscore the tension between harnessing AI for defensive purposes and preventing its misuse in an increasingly AI‑driven threat landscape.
