# Foreign adversaries are using Claude to train rival AI models, Anthropic says

Anthropic's threat intelligence head said on April 12 that state-linked actors are copying the company's models and undercutting it on price.

Foreign adversaries are accessing Anthropic's Claude models to train competing AI systems and sell cheaper copycat versions, the company's head of threat intelligence, Jacob Klein, said on April 12.[^1]

The disclosure puts a concrete shape on a threat that has been debated in general terms for months. This is not a roadmap concern or a speculative risk - Klein named the behavior: access the model, train on it, bring a lower-cost product to market. That describes an industrial operation, not an opportunistic hack.

The timing sits alongside a sharp political signal. US Secretary of Commerce Howard Lutnick said Anthropic is returning to what he called "the correct side" of the Trump administration.[^3] Treasury Secretary Scott Bessent went further on September 2, stating that an American defeat in the US-China AI race would negate every other US effort.[^5] The read here is that Klein's April disclosure is being folded into a broader government argument about AI competition - the adversary-use allegation gives the administration a product-level example to point to.

What the record does not carry is which foreign actors Klein named, which Claude versions were involved, how Anthropic detected the access, or what technical or legal steps the company has taken since April to close the gap. Five months is a long window between a threat-intelligence finding and a public filing, and the facts do not say why.
