US Expands DeepSeek AI Ban to Cover All Third-Party Software Built Using Chinese Models
From marketbrief.now
AI;DR
The U.S. Department of Homeland Security has expanded its ban on DeepSeek AI to require federal software vendors to identify and remove all third-party software built using the Chinese company's open-weight models, even if hosted on U.S. servers. The order, issued under the Federal Acquisition Supply Chain Security Act of 2018, mandates civilian agencies to purge any DeepSeek-derived weights from their IT systems and allows exemptions for mission-critical functions with 60 days' notice. China's Commerce Ministry has condemned the ban as discriminatory.
