Anthropic is challenging the Pentagon's claims about its control over AI technology in military systems, asserting it cannot manipulate its AI tool Claude once deployed. The company contends the Pentagon is retaliating against it, and a court rejected Anthropic's request to block Pentagon actions.

The claims regarding Anthropic's legal and contractual disputes with the Pentagon are largely supported by the evidence. The claim about Anthropic's inability to manipulate its AI tool Claude is contradicted by evidence suggesting potential manipulation capabilities. Anthropic's contention of Pentagon retaliation is supported by multiple sources discussing the legal context. The court's rejection of Anthropic's request and its legal victory in San Francisco are well-documented. The cancellation of the $200 million contract is also corroborated by several sources. Overall, the evidence provides a mixed but generally supportive picture of Anthropic's claims against the Pentagon.
