The external network has fallen into panic, caused by a Chinese company that created an AI model capable of matching or even surpassing OpenAI's latest version with only a training cost of 5.5 million dollars despite the lack of graphics cards, and it has just been open-sourced. These costs are far lower than the billions of dollars spent by OpenAI 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 as if the sky is falling, realizing that all of this was just a castle in the air. It is foreseeable that Nvidia, with a market value of 3.5 trillion dollars, will also be affected by this incident, and significant fluctuations in US stocks may occur on Monday.
