On February 28, Gelonghui (000997.SZ) said on the investor interactive platform that the company's big model is mainly used in two major scenarios: perceptual AI and cognitive AI. In terms of sensing AI, the company provides recognition and judgment of people, things, and objects based on rich intelligent data collection terminals, superimposing edge computing power, and launched edge intelligent gateway products and special AI modules for operators such as China Tower. At the same time, it lays out localized coverage of edge gateway chips and devices to build a trustworthy edge computing ecosystem. In terms of face recognition algorithms, technology expansion from payment scenarios to security scenarios has been realized, and through a security level inspection standard by the Public Security Institute, the prosthesis detection pass rate is over 95%, and the real pass rate is 100%. In terms of cognitive AI, the company cooperated with the Zidong Taichu University Model of the Institute of Automation of the Chinese Academy of Sciences, the ChatGLM Open Source Model of Tsinghua University, and the Baichuan Intelligent Open Source Model to improve the accuracy of existing neural network models while achieving rapid training support for new tasks and shortening the development cycle. Based on the ability to understand scenarios, the company deepens vertical scene requirements to form high-quality small model algorithms through data distillation, and uses them for vertical scene analysis and early warning. Up to now, the company's big model application services cover the fields of operators, educational institutions, etc.
