Former White House strategist Steve Bannon has voiced support for AI company Anthropic in its fight with the Pentagon over the use of Anthropic's technology in autonomous lethal weapons. The Pentagon has insisted on using Anthropic's AI system Claude for 'all lawful uses,' but Anthropic has refused, leading to the company being labeled a supply chain risk. Bannon believes Anthropic 'had it right' in demanding its tech not be used in such weapons, calling the situation 'almost too dangerous'.

Why it matters

This dispute highlights the growing tensions between tech companies and the military over the use of AI, particularly in weapons systems. Anthropic was founded with a focus on transparency and safety guardrails, and the company is arguing that current AI technology is not reliable enough to make life-or-death decisions. The outcome of this fight could set important precedents for the regulation of AI in the defense sector.

The details

The Pentagon has insisted it be allowed to use Anthropic's Claude AI system for 'all lawful uses,' but Anthropic has refused, leading to the company being labeled a supply chain risk - a designation typically reserved for foreign adversaries. Anthropic has sued the Pentagon over this, arguing that AI is not reliable enough for autonomous weapons. After negotiations over safety guardrards fell apart, President Trump ordered all federal agencies to stop using Anthropic products.

  • In late 2024, Anthropic began providing its technology to the Defense Department and intelligence agencies through a partnership with Palantir.
  • Last month, the Pentagon labeled Anthropic as a supply chain risk after negotiations over safety guardrails fell apart.

What they’re saying

“I think Anthropic had it right. It's very, very complicated. I really respect [Defense Secretary] Pete Hegseth . . . but I think in this situation, right, it's almost too dangerous. That's why you need a sort of atomic energy commission, you need some sort of modicum of [regulation].”
