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.

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

DeepSeek’s AI models reportedly rival OpenAI’s for a fraction of the cost and compute.

American AI stocks got sucker punched after China's DeepSeek app reportedly showed advancements against rivals sending investors into sell mode, shaving 3% off the Nasdaq.

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.

NVIDIA, the world's most valuable company until Monday, lost $600 billion of market value in a single day, the biggest in US stock history.

DeepSeek claims it costs them less than $6 million to train its latest AI models, while it costs ChatGPT $100 million. DeepSeek is able to charge only $0.14 per 1 million input tokens, compared to $15 at OpenAI. Token input pricing has to do with the amount of text that goes into training the AI language models.

Officials in the White House and FBI have begun a probe into DeepSeek to determine whether banned NVIDIA chips were used to create the R1 model.

U.S. President Donald Trump's administration is considering tightening restrictions on artificial intelligence leader Nvidia's sales of its H20 chips designed for the China market, Bloomberg News reported on Wednesday.
