WASHINGTON, Jan 30 (Reuters) - U.S. congressional

offices have been warned not to use Chinese artificial

intelligence app DeepSeek, Axios reported on Thursday, citing a

notice to the offices by the U.S. House of Representative's

chief administrative officer.

"At this time, DeepSeek is under review by the CAO and is

currently unauthorized for official House use," the notice said,

according to Axios.

The emergence of the low-cost Chinese AI model has

threatened the market dominance of U.S.-based AI leaders such as

OpenAI and Alphabet's Google.
