General Artificial Intelligence will change our production，lifestyle and thinking patterns.It becomes a new engine for economic development.In order to accelerate the in-depth application of artificial intelligence，cultivate and expand the artificial intelligence industry，explore a sustainable development path，this report has been compiled together with industry experts.In recent years，artificial intelligence has become a national strategy.The State Council and various ministries and commissions have issued the “New Generation Artificial Intelligence Development Plan”，the “Three-Year Action Plan to Promote the Development of the New Generation Artificial Intelligence Industry”，and the “Guidelines for the Construction of a New Generation Artificial Intelligence Open Innovation Platform”，etc.It is clearly proposed to focus on the independent，controllable and coordinated development of core artificial intelligence technologies，key products，and public support capabilities.The development of artificial intelligence is inseparable from three key elements：computing power，algorithms and data.These are interdependent and mutually reinforcing，and jointly promote the progress of artificial intelligence technology and the expansion of applications.How to break through the bottleneck of computing power，promote algorithm innovation，and broaden the boundaries of data is the route which must be passed for the development of artificial intelligence.Generative artificial Intelligence is the main manifestation of general artificial intelligence at the present stage.This report mainly focuses on the technological development of generative artificial intelligence on the basis of studying the core technologies required by general artificial intelligence.
