Nearly 40 employees from OpenAI and Google have submitted an amicus brief supporting Anthropic’s lawsuit against the US government. The lawsuit challenges the constitutionality of the government’s decision to designate the AI firm as a supply-chain risk. The legal fight highlights escalating tensions over the Pentagon’s use of AI in military technologies. In their filing, the engineers from OpenAI and Google argue that the Pentagon’s decision to blacklist Anthropic “introduces unpredictability in our industry that undermines American innovation and competitiveness”. Microsoft backed Anthropic’s request for a temporary restraining order against the Pentagon order, arguing that its determination should be paused while the court ​considers the case.
