Anthropic created similar claims concerning DeepSeek, saying it silently redirected selected customer requests to Claude without informing those users.

Anthropic's report additionally accused a number of other Chinese AI firms of large-scale unauthorized distillation, including Alibaba, Z.ai, Xiaomi and MiniMax.

Distillation itself is a common AI training technique in which outputs from a more capable model are applied to improve another model.

Anthropic describes these particular campaigns as "illicit" since it states they relied on sizeable numbers of fraudulent accounts, proxy services and, in some cases, stolen payment details or API credentials to bypass its restrictions. US-China AI Dispute Escalates.

Notably, the report comes shortly after the NSA, FBI and other US agencies accused a number of Chinese AI businesses of conducting industrial-scale efforts to obtain technology and outputs from American AI models. China rejected those allegations and accused Washington of trying to suppress its AI industry.

Anthropic notes the alleged rerouting creates another concern beyond intellectual property: users may have unknowingly sent sensitive information to a third-party American AI provider while believing they were communicating only with a Chinese service.

For now, these remain allegations created by Anthropic, and the businesses named in the report have not publicly provided detailed rebuttals to each of its claims. Stay Connected with ProPakistani.
