Export controls need to be tightened after revelations the Chinese company used Nvidia technology, the leaders of a congressional committee said.

WASHINGTON (Reuters) -Two members of U.S. Congress are calling on President Donald Trump's administration to consider restricting the export of artificial intelligence chips made by Nvidia, alleging Chinese AI firm DeepSeek has relied on them.

While the demand is there, it's clear that's not the sole reason why Nvidia's RTX 50 series is impossible to find in stores. Many retailers received fairly low stock quantities, as Nvidia reportedly experienced manufacturing issues.

DeepSeek stunned the tech world with the release of its R1 "reasoning" model, matching or exceeding OpenAI's reasoning model for a fraction of the cost.

A Chinese startup’s latest affordable artificial intelligence (AI) chatbot sent NVIDIA Corporation’s NVDA shares into a tailspin, erasing half a trillion in market capitalization. However, the widespread anxiety among NVIDIA investors is overblown.
