After Sam Altman, the father of ChatGPT, was dismissed as CEO by the OpenAI board, he made a comeback with the European version of OpenAI, 'Mistral AI', which avoids the risk of losing control through decentralized investment. The father of ChatGPT did not heed the brutality of the capital game, while Mistral AI took a more cautious approach. The even-numbered seats on the OpenAI board led to decision-making difficulties, which is a fundamental issue. In the business world, founders must pay attention to whether they can hold their ground, which is a significant challenge.

The resignation of OpenAI's founder as CEO has ignited an internal power struggle. AI entrepreneurs in both China and the U.S. are under pressure to become profitable, with significant differences in the investment markets. The era of large models presents new challenges for entrepreneurs, as the survival space for independent apps shrinks. Investors are focusing on different segments: application layers are gaining attention in China, while the investment market in the U.S. is booming. The differences in AI entrepreneurship between China and the U.S. stem from the maturity of large models and the activity level of the investment markets.
