How DeepSeek changed the market's mind

This Planet Money episode analyzes the market reaction to DeepSeek, a new AI model from a Chinese company. The podcast discusses how the release of DeepSeek, which reportedly achieved comparable performance to expensive American models at a fraction of the cost, caused a significant drop in the stock prices of companies like NVIDIA (chipmaker) and Constellation Energy (nuclear power provider), reflecting a shift in market assumptions about the future of AI. The unexpected success of DeepSeek challenged the prevailing belief that massive investment and high-end processors were essential for creating top-tier AI. The episode also explores the implications for the AI industry, suggesting a potential move towards AI models as a commodity and a reevaluation of the "AI arms race." One key takeaway is that DeepSeek's open methods allowed independent researchers to replicate the model, further validating its efficiency and potentially democratizing AI development.
