Anthropic vs. Pentagon — 3/24 Hearing Is Today

The preliminary injunction hearing before Judge Rita Lin takes place today at 1:30 PM PST at San Francisco federal court. This could set a landmark precedent for the entire AI industry.

Today’s key question:

• Judge Rita Lin decides whether to pause the supply-chain risk designation (preliminary injunction)
• Anthropic: Swore “no remote control post-deployment,” denied “ever demanding approval over military operations”
• Pentagon/DOJ: Terms of service unacceptable to the executive branch, claims sovereign national security judgment

Senator Elizabeth Warren calls blacklist “retaliation” (3/23 — new):

• Warren sent a letter to DOD characterizing the Anthropic blacklist as “retaliation”
• “I am particularly concerned that the DoD is trying to strong-arm American companies into providing the Department with the tools to spy on American citizens and deploy fully autonomous weapons without adequate safeguards”
• Separately wrote to OpenAI CEO Sam Altman requesting details of OpenAI’s agreement with the Pentagon
