The Pentagon, the labs and the limits on use

Who decides how the US military may use frontier AI: the government that buys it or the companies that build it?

The US defence relationship with frontier labs began with $200m pilot awards. Within 18 months it had become a fight over usage limits that reached the courts. This line follows the contracts, the ‘any lawful use’ demand, the Anthropic exclusion and OpenAI’s classified deal, through to the ruling and Project Meridian.
