[Step Star Jiang Daxin: Financial vertical large-scale models are moving from single-point applications to joint construction of financial AI infrastructure] On September 16, Jiang Daxin, founder and CEO of Step Star, said at the 12th anniversary innovation results conference of the interface that vertical large-scale models are accelerating their integration with financial production systems. Behind this is the transition of models from single-point application capabilities to infrastructure. FDE (forward deployment engineer) and SaS (service as software) are becoming new paradigms of service software. FDE is responsible for transforming business processes into production systems, and SaS is responsible for delivering service results in a software-based manner. The implementation of FDE is inseparable from long-term co-creation and the cultivation of compound talents among partners.
