- White House drafts executive guidance to let agencies bypass Anthropic's 'supply chain risk' label and access its newest model Mythos for defense and cybersecurity tasks.
- Pentagon labeled Anthropic a 'supply chain risk' in February and ordered a six‑month phase‑out of its technology across federal systems.
- Dario Amodei met with White House Chief of Staff Susie Wiles and Treasury Secretary Scott Bessent to discuss cybersecurity risks tied to Mythos and to negotiate renewed federal access.
- NSA is already running Claude Mythos Preview on classified networks, leveraging its ability to simulate a 32‑step corporate network attack in under 20 hours.
- Mozilla used Mythos to identify and patch 271 software vulnerabilities, demonstrating the model’s high‑impact security capabilities.
Why it matters: Federal agencies gain immediate access to Anthropic’s Mythos, a model that already patched 271 bugs, while the Pentagon loses leverage over AI supply‑chain risk, accelerating defense AI integration and reshaping procurement policy.
