Anthropic's head of national security policy, Tarun Chhabra, publicly accused Chinese AI company Zhipu of distilling its Claude model and OpenAI's models for Zhipu's GLM-5.2 at the Aspen Security Forum. Anthropic also accused DeepSeek of ongoing "adversarial distillation" and claims to be shutting down millions of distillation accounts weekly. Chhabra suggested the US government should collaborate with allies to restrict Chinese model adoption globally, similar to past telecom efforts.
