Should the AI tool Deepseek be banned similar to TikTok

For those not familiar the Chinese startup DeepSeek released an AI app last week that is similar to chatGPT. The app is powered by a China based model called DeepSeek r1, which directly competes with OpenAI’s o1 model.

This app has shot to the top of charts on IOS and play AppStores. It essentially offers for free what chatGPT plus offers users for $20 per month.

This cost reduction is largely driven by model efficiency where less gpu is required for the same level of performance. It was also achieved by a small startup competing directly with U.S based giants. This efficiency was largely motivated by Biden era sanctions on China relating to GPU. There are some questions about if the company has really achieved the claimed efficiency or is hiding sanctions violations.

This news has driven a significant dip in stock prices for nvidia and Microsoft, and follows closely on the heals of the stargate announcement.

My question is do you think Congress should act to immediately ban this app in the U.S. similar to how it banned TikTok? What guidelines or principles should be followed in making this decision? Any and all related discussion is welcome.
