**[Google AI Division Restructures Power, Four Veterans Depart, Stock Closes Down Over 4%]** BlockBeats News, August 6: Google DeepMind CEO Demis Hassabis announced this morning that he will step down from daily management duties, transitioning to the role of DeepMind Chairman and Alphabet Chief Scientist. He will continue to oversee long-term AI research and lead the pharmaceutical research company Isomorphic Labs. The development and delivery of Gemini will now be fully managed by former DeepMind CTO Koray Kavukcuoglu, who will report directly to Alphabet CEO Sundar Pichai. On the same day, legendary engineer Jeff Dean announced his departure from Google, taking Sanjay Ghemawat, Oriol Vinyals, and Quoc Le with him to jointly establish a company named Discovery Loop. The team aims to leverage AI to automate the entire scientific research process—from posing questions, designing experiments, executing experiments, to evaluating results. Google participated in the founding round of investment and will serve as its cloud service provider, offering computational support for the first year. For this top-tier research team that has decided to venture into entrepreneurship, Google chose not to enforce retention but will continue to maintain capital, cloud service, and research collaboration relationships. According to BIT (bit.com) market data, the announcement triggered a swift market reaction. Alphabet's stock price fell more than 5% intraday, ultimately closing down 4.03%. During after-hours trading, it rose 0.57%, closing at $364.49.
