Anthropic is challenging a US Department of Defense decision to exclude its Claude models from government use, alleging a 'supply chain risk' designation is a retaliatory move against its safety protocols. The lawsuit, supported by Microsoft and former military leaders, marks a critical legal battle over whether AI safety constitutions are protected by the First Amendment.
The US Department of Defense has signed a landmark deal with xAI for Grok AI integration while simultaneously issuing a Friday deadline to Anthropic. The Pentagon is threatening to label Anthropic a 'supply chain risk' unless it removes safeguards that restrict military access to its Claude models.
