OpenAI and Google Employees Back Anthropic in Lawsuit Against Pentagon Over Supply-Chain Risk Designation

Over 30 OpenAI and Google employees, including Google DeepMind chief scientist Jeff Dean, file an amicus brief backing Anthropic's lawsuit against the Pentagon after the Department of Defense designated the AI company a supply-chain risk, severely restricting its work with military contractors following a breakdown in negotiations over AI use restrictions including bans on mass surveillance and autonomous lethal weapons.

• More than 30 employees from OpenAI and Google, including Google DeepMind chief scientist Jeff Dean, file an amicus brief supporting Anthropic in its legal battle against the US government over the Pentagon's decision to designate the company a supply-chain risk.
• Anthropic sues the Department of Defense and other federal agencies, seeking a temporary restraining order after the Pentagon's sanction severely limits its ability to work with military contractors, stemming from a breakdown in negotiations over AI use restrictions including bans on mass domestic surveillance and autonomous lethal weapons.
• The amicus brief warns that blacklisting Anthropic undermines American innovation and competitiveness, chills professional debate on AI risks, and sets a dangerous precedent for the industry, with OpenAI CEO Sam Altman also publicly calling the Pentagon's decision 'very bad for our industry and our country.'
