Trump says DeepSeek a 'wake-up call' for US tech firms

DeepSeek is powered by the open source DeepSeek-V3 model, which its researchers claim was trained for around 6m ( 4.2m) - significantly less than the billions spent by rivals. But this claim has been disputed by others in AI. Its emergence comes as the US is restricting the sale of the advanced chip technology that powers AI to China. To continue their work without steady supplies of imported advanced chips, Chinese AI developers have shared their work with each other and experimented with new approaches to the technology. This has resulted in AI models that require far less computing power than before.
