US frontier AI companies warn authorities over sophisticated distillation attacks as China threatens countermeasures
↗
American AI developers and the government are concerned that foreign actors are using distillation attacks to train cheaper, faster alternative models using data from Western frontier models.
Distillation allows competitors to emulate high-level intelligence without the massive compute and financial investment required for original training. This threatens the business models of proprietary AI firms and is being framed as a national security issue.

Distillation attacks involve training smaller models by feeding them prompts and responses from more advanced models.
Foreign actors are reportedly bypassing safeguards by purchasing third-party conversation logs from legitimate accounts.
China has pledged countermeasures if the US uses these allegations to contain Chinese AI development.
THE READ
What the cluster adds up to.
US frontier AI companies are alerting authorities to distillation attacks, where smaller models learn to emulate the capabilities of advanced models by analyzing their outputs. This process allows developers to create models with similar intelligence at a fraction of the original cost and compute requirements. It is speculated that this method contributed to the development of Kimi K3 in 2026 and Deepseek in 2025.
Preventing these attacks is difficult because actors can circumvent detection by purchasing logs of conversations from legitimate third-party accounts. While some attacks are obvious, such as prompts attempting to force a model to output its internal reasoning verbatim, others are harder to halt. Anthropic reported in September 2026 that it had detected and countered various distillation attempts over the previous year.
The conflict highlights a divide between the proprietary, profit-driven models of US firms like OpenAI and Google and the open-weight models often found in China. US firms argue that distillation steals the value of their massive investments, while reports suggest some Chinese models, such as Inkling AI, may have used other models for early training data. This tension is expected to be a point of discussion during a meeting between US and Chinese leaders on September 24.
