Department of Homeland Security bans DeepSeek use in federal civilian agencies

The Department of Homeland Security has banned the use of DeepSeek models within US federal civilian agencies. This order requires government agencies to stop utilizing artificial intelligence tools from the Chinese startup DeepSeek immediately. The decision stems from security fears as the United States and China compete for dominance in the rapidly evolving AI sector. Consequently, these frontier AI models are no longer permitted for official use across the specified federal government civilian operations.
