By PulseAugur Editorial · [7 sources] ·

The U.S. Department of Homeland Security has issued a ban on the use of DeepSeek AI models and services across all federal civilian agencies. This directive, published in the Federal Register, cites concerns that DeepSeek could facilitate the transfer of sensitive U.S. government data to the Chinese government.

This action follows the recent release of DeepSeek's latest AI model, V4.1-Flash-1017, and comes amid broader U.S. efforts to restrict Chinese AI technology due to data security risks. AI
