Behind Closed Doors: NSA’s Secret Pact with Anthropic’s Blacklisted AI

When the Pentagon slammed the door on Anthropic - blacklisting the American AI developer over ethical disputes and supply chain fears - it seemed like the end of the road for any government use of its controversial “Mythos” AI model. Yet, in a twist worthy of a cyber-thriller, the National Security Agency (NSA) has not only kept the relationship alive but is actively relying on Mythos to power its most advanced cyber operations. The revelation, confirmed by multiple intelligence sources, shines a light on the shadowy, high-stakes tug-of-war over the world’s most potent artificial intelligence.

Anthropic’s Mythos isn’t just another AI chatbot - it’s a tightly guarded, bleeding-edge model engineered for offensive and defensive cyber operations. Unlike commercial language models, Mythos can swiftly uncover deep software flaws, construct functional exploit paths, and automate code audits at a scale and speed that was science fiction just a few years ago. These capabilities make it a double-edged sword: indispensable for cybersecurity defense, but too dangerous for broad release.

The Pentagon’s decision to blacklist Anthropic followed a dramatic breakdown in negotiations. The military wanted unrestricted access to Anthropic’s Claude models for wide-ranging AI integration. Anthropic, wary of contributing to mass surveillance and mission creep, refused. The fallout was swift: contracts canceled, lawsuits filed, and an official ban across all Department of Defense agencies.

Yet the NSA - tasked with defending the nation’s most sensitive networks - found these restrictions unworkable. According to sources, the agency quietly secured independent access to the Mythos Preview, joining an elite group of only 40 organizations worldwide. For the NSA, the technical edge provided by Mythos outweighed internal Pentagon politics and legal battles. The agency’s clandestine partnership with Anthropic reveals a stark divide between intelligence priorities and formal military regulations.

Recent secret meetings between Anthropic’s CEO and top U.S. officials suggest that new diplomatic channels are being forged. Insiders hint at a possible “special carveout” that would let critical intelligence agencies use powerful commercial AI models - within strict ethical and safety limits - even if other military branches remain locked out. If implemented, this could set a precedent for how the U.S. government balances national security imperatives with the risks of advanced AI in the hands of both state and private actors.

The NSA-Anthropic saga exposes the messy, secretive frontier of modern cyber warfare. As AI grows more capable - and more dangerous - the real battle may be over who gets to wield it, and at what cost to ethics, transparency, and public trust.

• Blacklisting: Blacklisting is blocking or banning specific items, like IP addresses or software keys, from use after they are found to be compromised or harmful.
• Exploit Path: An exploit path is a chain of vulnerabilities or steps attackers use to compromise a system, highlighting how multiple flaws can be exploited together.
• Code Auditing: Code auditing systematically reviews software code to detect bugs, vulnerabilities, and compliance issues, ensuring better security and adherence to standards.
• Offensive Cyber Capabilities: Offensive cyber capabilities are tools and methods used to attack, disrupt, or infiltrate digital systems, often for strategic or military objectives.
• Supply Chain Risk: Supply chain risk is the threat that a cyberattack on one company can spread to others connected through shared systems, vendors, or partners.
