What will Washington do about Chinese startup DeepSeek and its AI chatbot?

As the TikTok ban hangs in the air, the US investigates the security implications of another mega-popular Chinese app

• Who is behind DeepSeek and how did it achieve its AI Sputnik moment'?

The White House said on Tuesday that it was investigating the national security implications of DeepSeek's rapid rise.

The Chinese AI startup released an open-sourced problem-solving model, R1, that has wowed Silicon Valley. According to the company, the model uses far less computing power and far fewer chips - therefore far less money - to achieve the same or better results as its US counterparts. DeepSeek's app, an AI assistant, has rocketed to the top of app stores in the US and UK, though it suffered a cyberattack on Monday that led the company to limit registrations.
