Article

The US military used AI tools made by a company called Anthropic. These tools helped the military sort through information and do research. In February, the Pentagon said Anthropic was a problem. Now the Pentagon does not use Anthropic anymore.

Why did the Pentagon stop?

The Pentagon asked Anthropic to remove safety features from its AI. Safety features protect people from harm. Anthropic said no. The company worried about weapons and spying. So the Pentagon chose other AI companies instead.

The change was slow

Anthropic's AI was deep inside Pentagon computer systems. It was hard to remove quickly. The Pentagon used it for months after deciding to stop. Now the military uses different AI tools from other companies.
