Lei Jun, chairman of Xiaomi Group, said on Weibo that as early as 11 years ago, in 2014, we started the journey of chip research and development. We are well aware of the difficulty of chip manufacturing and have formulated a long-term and continuous investment plan: at least ten years of investment, at least 50 billion yuan, to be steady and cautious. In more than four years, as of the end of April this year, Xuanjie's cumulative R&D investment has exceeded 13.5 billion yuan. At present, the R&D team has more than 2,500 people, and the estimated R&D investment this year will exceed 6 billion yuan. Now, we have finally handed in the first answer sheet: Xiaomi Xuanjie O1, using the second-generation 3nm process, strives to be among the first-tier flagship experience.
