**DeepSeek AI: A New Challenger Rattles US Tech Giants**
In a dramatic shift within the tech industry, Chinese AI startup DeepSeek is upending the dominance of US giants Google, Nvidia, and Meta. The company’s pioneering R1 Large Language Model, touted as a cost-effective yet superior alternative to leading AI technologies, has triggered a significant market shake-up, eroding nearly a trillion dollars from the market value of American tech leaders. DeepSeek’s partnership with AMD further enhances its disruptive potential, posing serious questions about the sustainability and efficiency of existing tech giant models. As the Nasdaq Composite wavers amidst this upheaval, the rise of DeepSeek heralds a new era of AI innovation and competition, prompting a strategic reassessment among traditional tech powerhouses.
