# N.S.A. Lost Access to Powerful A.I. Model Amid Anthropic Dispute

> **Open Intelligence Dossier** · First detected: 2026-06-23 22:07 UTC · Category: Business

## Executive Summary
The N.S.A. has lost access to the Mythos A.I. model following reports that the technology identified vulnerabilities within classified U.S. government systems.

## Intelligence Brief
The National Security Agency is no longer utilizing the Mythos model, a powerful artificial intelligence system developed by Anthropic. This development follows reports that the model successfully identified security vulnerabilities within sensitive U.S. government infrastructure.


Coverage from AP News, Bloomberg, Reuters, CNBC, and The New York Times highlights a broader legal and operational dispute. Legal entities are suing the U.S. government regarding orders that restrict foreign access to top-tier Anthropic models, as well as the loss of access to specific tools like Fable AI.


Future developments will depend on the progression of ongoing lawsuits challenging government-imposed limits on AI model access. Coverage does not yet specify how the government plans to address the identified system vulnerabilities or if the N.S.A. will restore its connection to Mythos.
