On November 25th, Baidu made an announcement about the creation of two new departments: the Foundation Model Research and Development (R&D) Department and the Applied Model R&D Department. The Foundation Model R&D Department, under the leadership of Wu Tian, is tasked with developing highly intelligent and scalable general artificial intelligence large-scale models. In English, when referring to advanced technological concepts like this, using the full term "Research and Development" adds clarity and formality. Meanwhile, the Applied Model R&D Department, headed by Jia Lei, is dedicated to optimizing and delving into specialized models tailored for business application scenarios. In Western business and technological contexts, "delving into" is a more natural and commonly used phrase to express in-depth exploration compared to a simple "exploring".

Wang Haifeng will maintain his positions as Chief Technology Officer (CTO), Chair of the Technical Steering Committee (TSC), and Dean of Baidu Research. In international corporate settings, using the full and standard English titles like "Chief Technology Officer" and "Technical Steering Committee" is essential for clear communication. Both of these newly established departments will report directly to Robin Li, the CEO of Baidu.
