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.

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.

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