# US bans DeepSeek technology across federal civilian agencies

The Department of Homeland Security has banned federal civilian agencies from using AI technology from Chinese lab DeepSeek.

**Why it matters:** The ban extends the security-driven decoupling of US government AI use from Chinese models, arriving as China weighs its own export controls on open-weight models. Open-weight Chinese releases like DeepSeek's remain widely used by private developers, so the practical impact lies in procurement and contractor compliance.
