WASHINGTON: Pentagon bans Anthropic’s Claude AI from federal use after labelling the system a potential national security risk, according to officials familiar with the decision.

The move follows internal concerns about the use of advanced artificial intelligence systems in sensitive defence environments. Authorities have directed federal agencies to discontinue use of Anthropic’s Claude AI model, citing risks linked to military applications and control over critical data.

Tensions reportedly escalated after Anthropic declined certain defence related uses of its AI technology. The refusal raised questions within government and defence institutions about operational reliability, compliance and long term access in high security contexts.

Officials expressed concern that advanced AI systems, if not tightly governed, could create strategic vulnerabilities. These include issues related to data sovereignty, model control, system access and potential misuse in classified environments. The Pentagon’s position reflects broader debates within the United States about how artificial intelligence should be deployed across defence infrastructure.

The directive signals a cautious approach as military institutions increasingly rely on AI for logistics, intelligence analysis, cyber defence and operational planning. Authorities stressed that while artificial intelligence offers significant capabilities, deployment must meet strict national security standards.

The decision to ensure the Pentagon bans Claude AI underscores growing scrutiny of private sector AI providers operating in sensitive government domains. Officials indicated that future AI adoption will prioritise systems with clearly defined compliance structures, security assurances and operational alignment with defence requirements.

As the Pentagon bans Claude AI, the move may also influence procurement decisions across other federal departments evaluating AI partnerships in high risk environments.
