US DHS orders civilian federal agencies to remove DeepSeek products

According to a report by DEV Community, the US Department of Homeland Security issued an order through the Federal Register (notice number 2026-21447, filed on Oct 19) directing federal civilian administrative agencies to stop purchasing products from Hangzhou-based DeepSeek and to remove them from their IT systems. The order's scope extends beyond DeepSeek's own offerings: it also covers third-party products built using DeepSeek implementations, meaning vendors that embed DeepSeek models in their services cannot sell those services to the affected agencies. The DEV Community report surfaced the order on Oct 22. Private companies are not directly restricted by the order, though software vendors supplying civilian agencies are affected in practice, since they must either comply or stop serving the federal market. Notably, one of the cited original passages contrasts list prices on a typical workload, claiming that GPT-5 nano and GPT-6 Luna cost less than DeepSeek V4.1 Flash, though the pricing figures themselves are not stated. As of the latest available reporting, no further details have been published on enforcement arrangements or timelines for compliance.
