Why Anthropic’s Mythos Is Sparking Global Alarm

Anthropic PBC has said its new artificial intelligence tool, Mythos, is too powerful to release to the general public. The AI giant has described the model as so good at finding vulnerabilities in software and computer systems that it will only be released to a limited number of carefully chosen parties. If tools like Mythos fall into the wrong hands, Anthropic says, it could provide attackers with a powerful new weapon to steal data or disrupt critical infrastructure.

That risk was underscored when a small group of unauthorized users in a private online forum gained access to Mythos, according to a person familiar with the matter and documentation viewed by Bloomberg News. The group gained access on the same day that Anthropic first announced its plan to release the model to a handful of companies for testing purposes.
