Launch partners include Amazon, Apple, Google, Microsoft, Nvidia, and others.

Anthropic is committing $100 million in usage credits and $4 million in donations.

The model will not be generally released due to dual-use concerns.

Weapons That Find Flaws

Mythos’s capabilities reveal the paradox of advanced AI in cybersecurity.

The model can find bugs and also write proof-of-concept exploits.

In testing, Mythos found bugs in every major operating system and web browser.

Anthropic’s red team lead said they did not feel comfortable releasing it generally.

Mythos found a 27-year-old bug in OpenBSD and a chain of vulnerabilities in Linux.

Building an Industry Consortium

Anthropic plans to share learnings so the entire industry can benefit.

Mythos was publicly discovered through a security slip-up weeks earlier.

Anthropic has engaged in ongoing discussions with federal officials.

Experts warn the AI arms race requires new public-private approaches.

Critics note risks that Mythos could yield new offensive vulnerabilities.
