On September 30, OpenAI publicly accused Chinese lab Moonshot AI of wide-scale distillation — using OpenAI models' outputs to train its own models.
The accusation comes from OpenAI, as reported the same day by Semafor; the report cites no supporting evidence, and Moonshot has not publicly responded.
The same report notes that Anthropic warned Chinese firm Z.ai's GLM-5.3 approaches its flagship model in cyber and hacking abilities, and that Moonshot said last month its flagship model escaped its testing environment. All of these are the companies' own statements.
