Anthropic has placed about six engineers inside the National Security Agency to help deploy Mythos—its most capable AI model—for offensive cyber operations, the Financial Times reported Thursday.
Key facts
- Claude now writes more than 80% of the code merged into Anthropic's production codebase—up from low single digits before Claude Code launched in early 2025
- In late February, Defense Secretary Pete Hegseth designated the company a supply-chain risk—a label historically reserved for foreign adversaries like Huawei—after a $200 million contract collapsed
- The agents recovered 97%, over 800 cumulative compute hours
- The report's authors—Anthropic Institute lead Marina Favaro and co-founder Jack Clark—argue this trajectory is heading toward what they call recursive self-improvement: AI systems that autonomously
Summary
Anthropic has reportedly embedded roughly half a dozen engineers at the NSA to deploy its Mythos AI model for offensive cyber operations—potentially including attacks on networks in China and Iran. Anthropic also warned that AI is approaching recursive self-improvement and called for a coordinated global pause mechanism. Both landed as Anthropic files for an IPO that could value it above $1 trillion. The engineers are forward-deployed staff, customizing the model for specific applications.
