what is Deepseek ?

DeepSeek is a Chinese artificial intelligence (AI) company focused on advancing AI research and development, particularly in the field of large language models (LLMs) and their practical applications.

The emergence of DeepSeek has had a significant impact on the U.S. stock market. Global technology stocks experienced a massive sell-off, wiping out up to $1 trillion from U.S. stock markets. Nvidia, a major player in AI hardware, suffered the most substantial loss, with its stock price dropping 17% in a single day, resulting in a nearly $600 billion decrease in market value—the largest one-day loss for any U.S. company in history. This downturn was driven by concerns that DeepSeek's efficient AI model could reduce the demand for advanced chips, leading investors to reassess the high valuations of U.S. tech companies.
