The General Services Administration said Grok-4 failed to meet federal safety and alignment standards. The National Security Agency identified security vulnerabilities unique to Grok — absent from models like Anthropic's Claude — in a classified November 2024 review. The Biden-era Chief Digital and AI Office declined Grok entirely, citing training data opacity and weak guardrails. White House Chief of Staff Susie Wiles personally contacted a senior xAI executive after the warnings reached her office.
Then, during the week of February 27, 2026, the Pentagon authorized xAI's Grok for use in classified military environments under a contract worth up to $200 million — shared with Google, OpenAI, and Anthropic. The Wall Street Journal reported the full sequence the same day.
What Each Agency Found
The Pentagon approved Grok for classified military environments during the week of February 27, 2026. No public disclosure was made of what remediation steps, if any, addressed the documented GSA and NSA concerns before authorization proceeded.
Why This Matters
The Grok approval is the highest-profile example to date of AI safety evaluations being overridden in a sensitive federal context. The paper trail is unusually complete — multiple agencies, a classified NSA review, a White House escalation, and a formal GSA report — making it difficult to argue the risks were unknown.
Public Citizen stated on February 27 that the deployment "disregards internal warnings and could compromise national security." The broader concern is structural: if documented safety failures do not block deployment in classified environments, what function do the evaluations serve?

When internal government reviews call a model unsafe and the Pentagon approves it anyway, the question is no longer whether AI safety evaluations matter — it's whether anyone is required to follow them.
