US orders federal purge of DeepSeek over national security concerns

The US Department of Homeland Security ordered federal agencies to remove DeepSeek technology from government systems and banned future purchases, citing national security risks including data transmission to China. The restrictions also cover third-party products built using DeepSeek models. Separately, DeepSeek open-sourced its DeepInfer inference framework and deepseek-recipe components, offering developers access to technology previously used internally to operate its AI models.
