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.

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.
