OpenAI announces Pentagon deal after Trump bans Anthropic

President Trump ordered the U.S. government to stop using the artificial intelligence company Anthropic's products and the Pentagon moved to designate the company a national security risk on Friday, in a sharp escalation of a high-stakes fight over the military's use of AI.

Shortly after the president's announcement, rival company OpenAI said it had done a deal with the Defense Department to provide its technology for classified networks.
