Dong Yu, who previously served as the Deputy Director of Tencent AI Lab, has tendered his resignation, citing personal development considerations. Within Tencent's AI ecosystem, Yu is a highly experienced and seasoned professional. He possesses in - depth and extensive expertise in speech processing, natural language processing (NLP), and digital human technology. Since joining Tencent in 2017, Yu has spearheaded his team, resulting in the publication of hundreds of papers at leading academic conferences and in top - tier journals. His efforts have been instrumental in driving the widespread application of NLP, speech, and digital human technologies across various sectors of Tencent's business operations. Moreover, he played a central and crucial role in the development of Tencent's large - scale model, 'Hunyuan.' Starting from 2025, major tech companies have come to a consensus that foundational models represent the core competitive advantage. In response, Tencent has implemented a series of strategic adjustments centered around large - scale model development. On one front, Tencent has significantly increased its investment in talent. It has successfully recruited top - notch professionals, such as Shunyu Yao, a former researcher at OpenAI. Additionally, it has attracted key employees from companies like ByteDance and Alibaba. On the other hand, Tencent has streamlined its internal R&D resources. It has established new departments within the Technology Engineering Group (TEG), including the AI Infra Department, AI Data Department, and Data Computing Platform Department. These moves are aimed at clearly defining model development responsibilities and enhancing R&D efficiency. At present, the large - scale model market is characterized by intense competition. Tencent's adjustment initiatives are of paramount importance for its future development in this highly competitive field.
