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

Two U.S. Congress members 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.

The Trump administration is reportedly considering expanding the bans and sanctions against China, which could mean that the Nvidia H20 chip will no longer be legal to sell in the country.

The economic hardware/software debate about China just got more complicated. Before DeepSeek flipped the script on the artificial intelligence game, many economists worried China had way too much of the former and not enough of the latter.

Government policies, generous funding and a pipeline of AI graduates have helped Chinese firms create advanced LLMs.

Chinese AI firm DeepSeek says it is facing "large-scale malicious attacks", which are affecting its services. Chinese state media is citing cyber security experts who say the attacks are originating from US-based IP addresses,

Deepseek collects similar data to American-based AI models, but Chinese laws could make that data more accessible to the government.

Security experts are urging people to be cautious if considering using emerging AI chatbot DeepSeek because of the app’s links to China and the potential implications for personal data. The chatbot has upended the AI market with its emergence as a rival to the likes of ChatGPT and OpenAI,
