Claude Mythos explained: Is Anthropic's most powerful AI model really too dangerous to release to the public?

Anthropic's Claude Mythos AI model has been kept under wraps due to concerns over its potential to accelerate the discovery and exploitation of software vulnerabilities. The model has identified thousands of serious vulnerabilities in major operating systems and browsers, including some that had gone unnoticed for decades.
Anthropic has unveiled its Claude Mythos Preview model as part of Project Glasswing, a initiative to contain and direct the model. Mythos is Anthropic's most capable model to date, with strong performance in coding and long-context reasoning. It has identified thousands of serious vulnerabilities in major operating systems and browsers. The model's capabilities have raised concerns about its potential impact on cybersecurity. Anthropic is investigating reports of unauthorized access to the model through a third-party environment. Mythos can turn both newly discovered flaws and already-known vulnerabilities into working exploits, even against software with unavailable source code.
