The following is the original Weibo text:
This year marks the 15th anniversary of Xiaomi's founding.
As early as 11 years ago, in 2014, we began our journey in chip research and development.
In September 2014, the Surge project was initiated. In 2017, Xiaomi's first mobile phone chip &#34;Surge S1&#34; was officially unveiled, targeting the mid-to-high-end market. Later, due to various reasons, we encountered setbacks and paused the development of SoC large chips. However, we retained the spark of chip research and development and shifted to the &#34;small chip&#34; route. Subsequently, various Surge chips were launched, including fast charging chips, battery management chips, imaging chips, antenna enhancement chips, and other &#34;small chips,&#34; gradually accumulating experience and capabilities in different technological tracks. Over the years, many Mi fans have been asking whether Xiaomi would still develop large chips. There have been various misleading rumors online, and many have mocked the lack of follow-up on Surge SoC. But I want to say, that is not our &#34;black history,&#34; that is our journey so far.
At the beginning of 2021, we made a significant decision: to enter the automotive industry. At the same time, we made another major decision: to restart the &#34;large chip&#34; business and resume the development of mobile phone SoCs.
Xiaomi has always had a &#34;chip dream&#34; because to become a great hardcore technology company, chips are a peak that must be climbed and an unavoidable hard battle. We deeply summarized the lessons learned from our first chip-making experience. We found that only by developing high-end flagship SoCs can we truly master advanced chip technology and better support our high-end strategy.
Thus, at the beginning of the Xuanjie project, we set very high goals: the latest process technology, flagship-level transistor scale, and first-tier performance and energy efficiency.
At the same time, we are well aware of the difficulties in chip manufacturing and have formulated a long-term continuous investment plan: at least ten years of investment, at least 50 billion RMB, steadily advancing step by step.
In just over four years, as of the end of April this year, the cumulative R&amp;D investment in Xuanjie has exceeded 13.5 billion RMB. Currently, the R&amp;D team has surpassed 2,500 people, and the expected R&amp;D investment this year will exceed 6 billion RMB. I believe that this scale ranks among the top three in the domestic semiconductor design field, both in terms of R&amp;D investment and team size. Without immense determination and courage, and without sufficient R&amp;D investment and technical strength, Xuanjie would not have reached today.
Now, we have finally delivered our first answer: Xiaomi Xuanjie O1, using the second-generation 3nm process technology, striving to rank among the first-tier flagship experience
Xiaomi's chip journey has spanned 11 years, but in the face of our peers' accumulation in chip technology, we can only say we are just getting started.
Chips are the core underlying track for Xiaomi to break through hardcore technology, and we will definitely give it our all. Here, we sincerely ask everyone to give us more time and patience, and support us in our continuous exploration on this path.
