OpenAI says it has found evidence that Chinese artificial intelligence start-up DeepSeek used the US company’s proprietary models to train its own open-source competitor, as concerns grow over a potential breach of intellectual property.

White House artificial intelligence czar David Sacks said there’s “substantial evidence” that Chinese upstart DeepSeek leaned on the output of OpenAI’s models to help develop its own technology.

It’s impossible to look at the Chinese artificial intelligence startup DeepSeek’s new AI model without comparing it against OpenAI, the dominant American rival.

ChatGPT creator OpenAI said on Tuesday said that Chinese firms are "constantly" trying to tap into U.S. rivals to improve Chinese artificial intelligence models.

The product is not approved for government use yet, but OpenAI of course hopes President Trump will speed things up.
