LONDON, Jan 27 (Reuters) - U.S. Treasury yields fell to

three-week lows on Monday as investors sought the safety of

government bonds as tech stocks tumbled on the surging

popularity of a Chinese discount artificial intelligence model.

The benchmark 10-year Treasury yield dropped 10

basis points to 4.52%, its lowest level since Jan. 2.

The two-year yield fell 8 bps to 4.19%, its lowest since

mid-December.

The rush to bonds came as stocks, particularly tech stocks,

fell around the world, as the popularity of a Chinese discount

artificial intelligence model jolted investors' faith in the

profitability of AI and the sector's voracious demand for

high-tech chips.

Nasdaq futures were last down 4.4% and European tech

stocks shed 5.1%.
