- Jeff Dean led a coalition of more than 30 AI researchers from OpenAI and Google in filing an amicus brief that backs Anthropic in its lawsuit against the U.S. Department of War.
- Anthropic is challenging a “Supply Chain Risk” label imposed by the U.S. Department of War, which it says is improper retaliation that could cost the company up to $5 billion.
- The brief argues that the supply‑chain risk designation harms the public interest and that Anthropic’s technical concerns about surveillance and autonomous weapons are legitimate.
- OpenAI staff publicly endorsed the brief on X, emphasizing industry solidarity and the need to protect AI research from governmental overreach.
- FIRE, along with EFF, Cato, Chamber of Progress, and the First Amendment Lawyers Association, joined the brief, adding civil‑liberties support to Anthropic’s case.
- Business Insider reported that Anthropic could lose $5 billion in its dispute with the Pentagon, underscoring the high stakes of the legal battle.
Why it matters: The brief bolsters Anthropic’s fight against a supply‑chain risk label that the lawsuit claims is retaliation, potentially averting a $5 billion loss and setting a precedent that could curb future Pentagon restrictions on AI firms, while signaling strong industry solidarity overall.
