# US Government Bans Chinese DeepSeek AI Models Civilian agencies must remove DeepSeek technology due to escalating national security and intellectual property concerns. - **Source:** [BBC News](https://www.bbc.co.uk/news/business) - **Published:** 2026-10-19 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/8a7f8351-b523-44eb-a74d-daf7309c23a2 ## Mandatory Removal of DeepSeek The Department of Homeland Security has officially ordered the removal of all DeepSeek AI technology from civilian government systems. This directive applies to agencies including the Department of the Treasury, the Department of State, and the Department of Justice. Notably, the Department of Defense remains excluded from this specific federal mandate. ## Retrospective Enforcement Timeline Although the Department of Homeland Security made the order public on Monday, the ban actually took effect at the end of July. This retrospective application highlights the urgency with which the administration is addressing potential security risks. The policy targets both direct software usage and any technology developed using DeepSeek models. ## Intellectual Property Allegations Major American AI firms, specifically Anthropic and OpenAI, have alleged that their proprietary models were copied by Chinese entities, including DeepSeek. White House tech lead Michael Kratsios previously noted in an internal memo that malicious exploitation of American AI firms by Chinese rivals has been occurring, prompting this aggressive regulatory response. ## Economic Disruption of Models DeepSeek has gained significant market traction due to its open-source nature and extremely low development costs. The company reported spending approximately $6 million to train its debut model, contrasting sharply with the $100 million estimated for OpenAI's GPT-4. These cost discrepancies have previously caused volatility in global technology stock markets. ## Widespread Commercial Integration Despite the government ban, DeepSeek remains popular among private US tech companies. Firms such as Snowflake, Vercel, and OpenRouter incorporate these models into their customer offerings to reduce operational expenses. The model's free chatbot application also consistently ranks among the most downloaded tools in the Apple App Store globally. ## Performance and Competitive Threat The latest version of DeepSeek, released last week, has received praise for its coding capabilities, with some users claiming it outperforms advanced OpenAI tools. This performance level, combined with its disruptive pricing, positions DeepSeek as a significant competitor in the ongoing AI race between the United States and China. ## Strategic Geopolitical Tensions President Donald Trump has explicitly identified China as the primary rival in the development of artificial intelligence, viewing the technology as essential to national security. This ban represents a broader effort to decouple critical infrastructure from Chinese-developed AI, following persistent criticism from the current administration regarding the security of foreign models. ## Future Regulatory Implications The exclusion of the Department of Defense from this ban suggests a nuanced approach to national security, focusing primarily on civilian data integrity. As AI development continues to accelerate, the government's ability to monitor and restrict the integration of foreign open-source models will likely become a central pillar of future technology policy. ## Sources covering this story - https://www.bbc.co.uk/news/articles/cjkgeq0k1wevo?at_medium=RSS&at_campaign=rss — --- _Summary written by Brifing from the original reporting.
