American

artificial intelligence

(AI) giant

Anthropic

has accused its Chinese AI rivals

DeepSeek

Moonshot

on Thursday of covertly routing customer requests to its Claude models, then showing users the responses as if they were from their own models.

The new allegations mark a further escalation in US criticism of China’s AI industry practices. Earlier this week, three US government agencies, including the

National Security Agency (NSA)

Federal Bureau of Investigation (FBI)

, claimed that six Chinese companies were engaged in an industrial campaign to steal US model outputs, “likely with Chinese government awareness”.

Beijing on Wednesday rejected those allegations, describing them as actions by Washington to suppress China’s AI industry and threatening retaliatory measures.

While US companies

and Anthropic have repeatedly accused their Chinese counterparts of

“stealing” their outputs to improve their own models

in a process known as “distillation”, Anthropic’s latest claims mark the first time it has accused Chinese companies of re-routing users directly to

, which would expose Chinese users’ information and activity to the American company.

“[These] findings raise concerns about the misuse of user data by PRC AI labs,” the company said in its 154-page report released on Thursday.

According to the report,

Kimi model developer Moonshot

secretly showed its users Claude model outputs and passed them off as Kimi’s, then used those exchanges to improve their own models.
