The real meaning of the DeepSeek drama

The market reaction, when it came, was brutal. On January 27th, as investors realised just how good DeepSeek’s “v3” and “R1” models were, they wiped around a trillion dollars off the market capitalisation of America’s listed tech firms. Nvidia, a chipmaker and the chief shovel-seller of the artificial-intelligence (AI) gold rush, saw its value fall by $600bn. Yet even if the Chinese model-maker’s new releases rattled investors in a handful of firms, they should be a cause for optimism for the world at large. DeepSeek shows how competition and innovation will make ai cheaper and therefore more useful.
