The Trump administration has banned DeepSeek AI from most US civilian federal agencies, ordering the removal of the Chinese company's models and technology developed using them. The Department of Homeland Security did not specify the security threats behind the decision. The BBC reports: The order (PDF) is broad, as it requires agencies to ditch "all DeepSeek and DeepSeek-affiliate products, and third-party products and services developed using DeepSeek implementations." Complying will be tricky as it is not clear which third-party products and services have been developed using DeepSeek's wares. Nor is it clear whether "developed using" means providing ongoing access to DeepSeek models via API or simply refers to any app vibe-coded with the help of DeepSeek. It also leaves open the question of AI gateways. Services such as OpenRouter and Vercel AI Gateway make DeepSeek's models available through APIs. And those using gateway services may find themselves using DeepSeek models without meaning to do so. OpenRouter, for example, "routes requests to the best available providers for your model." It selects what the service deems to be the best fit provider of AI services. Vercel AI Gateway does the same by default. So federal civilian agencies could be using DeepSeek models inadvertently, if they haven't taken steps to constrain their AI providers.Read more of this story at Slashdot.
