Wen co-led "A Survey of Large Language Models" — at the time of publication, the most-cited overview of the field — with collaborators across Renmin University and other Chinese institutions. The framing of the survey was important: not a Western-centric overview translated for Chinese readers, but a synthesis written from the Chinese academic NLP community's vantage point, with attention to architectural decisions and training-data choices specific to multilingual and Chinese-language pretraining. His longer arc — IR foundations, MSRA tenure, current institutional roles at BAAI and Renmin — gives him standing to write that synthesis with authority on both sides of the LLM ecosystem.

Worth following when
you want a foundational LLM-landscape survey written from inside the Chinese academic AI community rather than translated into it.
Topics
comprehensive surveys of the LLM landscape; the Chinese-language AI research ecosystem; IR-side foundations of modern language models.
Key works
"A Survey of Large Language Models" (2023, senior author with Zhao and collaborators); foundational IR work from MSRA and Renmin; ongoing leadership of BAAI research direction.
