Anthropic alleges DeepSeek and Moonshot used fake accounts to distill Claude

Anthropic has detailed what it describes as distillation efforts by Chinese AI companies, saying DeepSeek and Moonshot used thousands of fake accounts and millions of real user queries to clone its Claude capabilities, according to a Wall Street Journal report summarized by Techmeme. The account says user queries were routed to Claude through "transfer stations" located outside China, with responses then presented as the Chinese firms' own output. The disclosure is Anthropic's characterization of the activity; the report does not include a response from DeepSeek or Moonshot, and no independent verification of the scale or method is provided in the supplied summary.
