Summary
Xiaojian Wu is an AI researcher-engineer with 11 years of experience building large language models, multimodal systems, and agent architectures from academia to industry. Based in the San Francisco Bay Area, he has driven core LLM and RLHF work at Meta (contributing to Llama 3), led NLP and IR efforts at Microsoft AI for Bing, and now splits his time between OpenAI and co-founding Anuttacon where he heads LLM pretraining, post-training, and multimodal research. His background blends rigorous academic training (PhD in CS) and postdoctoral research in stochastic planning and optimization with hands-on production research on RAG, summarization, and sparse personalization. Xiaojian is comfortable spanning theory and engineering—designing algorithms, scaling pretraining, and integrating agents into applications—and he actively hires and grows research teams. Colleagues value his ability to translate complex research into products that scale, and his career shows a steady move from foundational research toward building deployed AI systems.
