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.

Investors definitely weren’t thinking this way on Monday, concerned about reports that Chinese artificial-intelligence service DeepSeek was substantially cheaper and better than OpenAI.  This is a good time to remind all investors that the stock market is really just a manic crowd.

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.
