The White House imposed export controls on Anthropic's powerful Mythos AI model partly over suspicions that a China-linked group had accessed it, according to a person familiar with the matter.
The decision marks a significant escalation in the U.S. government's efforts to restrict advanced AI technology from reaching geopolitical rivals. It underscores growing national security concerns around the proliferation of frontier models.
Specific details on the alleged access remain undisclosed, and the source did not provide evidence linking any group to the incident. The controls were enacted under existing export regulations.
The move could set a precedent for how the U.S. regulates other cutting-edge AI systems. It may also heighten tensions with China, which has denied similar allegations in the past.
Critics argue that such broad controls risk stifling innovation and could push AI development overseas, away from U.S. oversight.
