US bans DeepSeek AI from government use as tech tension with China continues

The US has ordered all artificial intelligence (AI) technology from the Chinese firm DeepSeek to be removed from most government systems.

The Department of Homeland Security (DHS) has banned all use of DeepSeek within civilian government agencies, and any technology built with the aid of its AI models.

As a powerful AI model that is open source - meaning it is free to access and less expensive to use - DeepSeek has been seen as a disruptive force in the ongoing AI technology race.
