On November 2, at the opening ceremony of Hong Kong FinTech Week 2026, Du Xiaoman, in collaboration with the Hong Kong University of Science and Technology (HKUST) and the Hong Kong Generative AI Research and Development Center (HKGAI), unveiled the Xuanyuan 4.5 finance-enhanced large language model. This model is the first in the financial sector to apply self-evolving RSI technology to both model training and agent scenario goal adaptation, and comprises two components: a large language model and a multimodal model. With the integration of RSI technology, Xuanyuan 4.5 achieved a 30% improvement in core financial scenarios—including customer acquisition, risk control, and customer management—at only 10% of the cost of general-purpose models. Building on Xuanyuan, Du Xiaoman has developed over a thousand agents and more than 5,000 skills, with average daily Token usage exceeding 100 billion.
