AI company Anthropic said on February 27, 2026, it would not give the US Defense Department unrestricted use of its technology despite being pressured to comply by the Pentagon. Washington had given the artificial intelligence startup until Friday to agree to unconditional military use of its technology, even if it violates ethical standards at the company, or face being forced to comply under emergency federal powers. Hours later, OpenAI CEO Sam Altman announced a deal with the Pentagon to use its models with similar red lines to Anthropic, using "technical safeguards" that the Department of Defense had agreed to.
