DeepSeek, a Chinese artificial intelligence (AI) start-up, is sending shock waves through the U.S. tech sector by demonstrating its latest AI assistant, which achieves performance comparable to or even surpassing some of the world's best chatbots.

Nvidia crossed below its 200-day moving average this week for the first time since 2023. Analysts say the correction could deepen.

According to a paper authored by the lab, the DeepSeek-R1 model outperforms cutting-edge models such as OpenAI’s o1 and Meta’s Llama AI models across multiple benchmarks.
