US prohibits use of China’s DeepSeek by government

The US government on Monday ordered its agencies to stop using artificial intelligence (AI) tools from Chinese start-up DeepSeek, as the countries race for dominance in the fast-moving sector.

A notice from the US Department of Homeland Security announced the ban on products developed by DeepSeek — and tools created using DeepSeek by third parties — saying they must be removed from IT devices.

The department can issue direction to civilian agencies, but not the military or intelligence services. The US Department of Defense did not respond to a request for comment.

“DeepSeek’s models present multiple threat vectors,” a document attached to the notice said.

Use of DeepSeek AI tools “may result in the transfer of sensitive data to [China] if used by US government employees or vendors,” the department said.

Its servers are in China, where the legal system permits the government “extensive authority” to access private company infrastructure, it said.

DeepSeek, one of China’s top AI labs, shook up the industry in January last year with a low-cost, high-performance chatbot, challenging assumptions of US dominance.

The firm released a long-awaited new model, V4, in April, and this month updated a faster, more lightweight version of V4.

The US has accused DeepSeek and other top Chinese AI firms of systematically stealing the capabilities of cutting-edge models developed by US rivals.

Despite their fierce competition in the field, China and the US in September agreed to set up a “communication channel” for AI incidents.

The topic is expected to arise again when the countries’ leaders meet next month at a summit in Shenzhen, China.
