US Department of Homeland Security bans civilian government agencies from using DeepSeek

The US Department of Homeland Security has ordered the removal of DeepSeek-related technology from most government systems, prohibiting civilian government agencies from using DeepSeek and any technology built with its models; the ban takes effect at the end of July, and agencies under the Department of Defense are not included. The report notes that DeepSeek said last year that training the initial version of its model cost about $6 million, while OpenAI's GPT-4-related costs were about $100 million, and that US companies such as Snowflake, Vercel, and OpenRouter have also integrated DeepSeek into their products.
