The external network has fallen into panic, caused by a Chinese company that, despite the lack of graphics cards, has created an AI model that can rival and even surpass OpenAI's latest version with just a training cost of $5.5 million, and has just been open-sourced. These costs are far lower than OpenAI's tens of billions of dollars and even less than the salary of a senior executive from Facebook's AI team. Meanwhile, the United States has invested hundreds of billions of dollars in the AI field, leading investors to feel like the sky is falling; it turns out all of this was just a house of cards. It is foreseeable that Nvidia, with a market value of up to $3.5 trillion, will also be affected by this incident, and there may be significant fluctuations in the US stock market on Monday.
