Pentagon Chooses OpenAI AI Models After Trump Blocks Anthropic

The Pentagon has chosen OpenAI's artificial intelligence (AI) models after an order from Donald Trump to halt the use of Anthropic's models, which refused to grant unlimited access to the U.S. military. OpenAI committed to implementing technical safeguards for the safe use of its models, including a ban on mass surveillance and human accountability in the use of force. Trump accused Anthropic of “ideological whims” and warned that he would use all presidential powers to enforce compliance, characterizing it as a risk to the supply chain. This move marks an unprecedented response from the U.S. government against an AI company and creates a precedent for how legislation will limit the use of AI in the military sector.
