The Pentagon is actively testing various artificial intelligence models to determine the preferences of its 25 'super users,' according to a senior U.S. Department of Defense official. According to Jin10, the U.S. military is accelerating its search for alternatives to Anthropic's Claude. The testing began in early March, just three days after Defense Secretary Hegseth identified Anthropic as a supply chain risk. Following its decision to part ways with Anthropic, the Pentagon has set a six-month timeline to phase out the company's products. Earlier this month, the Pentagon announced new agreements with several other companies to use their AI tools on classified networks, aiming to develop multiple new supplier models.
