In the gold rush of artificial intelligence, NVIDIA and OpenAI were once seen as the "strongest partners." However, this once-closely-knit alliance seems to be entering a "post-honeymoon" phase. Recently, NVIDIA's CEO Jim Huang openly stated that the company's $3 billion investment in OpenAI is likely to be the "last one."

This statement came as a major shock to Silicon Valley. After all, the two companies had previously announced a $10 billion investment vision in September of last year. At the time, the market logic was straightforward: NVIDIA would invest money to buy shares in OpenAI, and OpenAI would then use that money to purchase an equivalent or even greater amount of NVIDIA chips. This "left-hand to right-hand" cycle was expected to build an unbreakable business loop. However, Huang's statement that the billion-dollar plan "is unlikely to be realized" shows that this chip giant has chosen to step back decisively when facing potential investment bubbles.

NVIDIA's withdrawal is not without reason. OpenAI is currently going through a turbulent period. This week, the head of OpenAI's robotics and consumer hardware division, Kalinovsky, resigned abruptly and publicly criticized the company's leadership in his resignation statement. He revealed that OpenAI had agreed to deploy AI models into the U.S. Department of Defense's classified network without sufficient discussion. This crude trade-off between security and commercial interests has not only caused internal turmoil but also intensified external doubts about its technological boundaries and ethical standards.

The market generally believes that NVIDIA's significant reduction in investment is aimed at preventing potential valuation overheating risks in the AI industry, while also examining the stability of OpenAI's internal management and strategic direction.

As the enthusiasm of capital begins to fade, the model of simply "investing in computing power" is facing great challenges. NVIDIA's cold shock may mark the beginning of the entire AI industry returning to rationality and re-examining the essence of business.
