Defense Secretary Pete Hegseth's order to phase out Anthropic's Claude AI from the Pentagon is meeting significant resistance from military personnel and IT contractors. Despite being labeled a 'supply-chain risk' due to guardrail disputes, users argue the tool is technically superior to alternatives like xAI's Grok.
OpenAI has reached a historic agreement to deploy its AI models across the U.S. Department of Defense's classified networks, coinciding with a record $110 billion funding round. The deal follows a dramatic executive order from President Trump banning rival Anthropic from all federal agencies due to its refusal to grant broad 'lawful purpose' access to its technology.
OpenAI has signed a landmark agreement with the U.S. Department of Defense to provide AI services, hours after President Trump issued an executive order banning federal agencies from using technology from rival Anthropic. The move signals a massive shift in the AI competitive landscape, favoring OpenAI as the primary national partner for defense and security.
President Trump has ordered all federal agencies to cease using Anthropic’s AI technology following a high-stakes standoff over military safeguards. The move, which includes a 'supply chain risk' designation, marks a significant escalation in the conflict between Silicon Valley’s safety-first AI labs and the administration’s national security priorities.
