Why is Anthropic keeping its new AI model Claude Mythos Preview private instead of releasing it?

Anthropic is keeping Claude Mythos Preview private because of its unprecedented cybersecurity capabilities that pose significant risks if misused. The model has demonstrated the ability to autonomously discover and exploit zero-day vulnerabilities—previously unknown security flaws—across major operating systems and web browsers. According to Newton Cheng, Frontier Red Team Cyber Lead at Anthropic, the company does not plan to make the model generally available due to concerns about rapid AI capability proliferation. They fear that if such powerful tools fall into the hands of malicious actors, the consequences for economies, public safety, and national security could be severe. Instead of releasing it publicly, Anthropic has partnered with over 40 organizations responsible for critical software infrastructure, including tech giants like Amazon, Apple, Google, and Microsoft, to responsibly use the model for vulnerability discovery and patching. This controlled approach allows security improvements while preventing weaponization of the technology.
