The new generation of artificial intelligence (AI) technology has led to systematic and revolutionary changes in the field of education. As a key element in the process of education and teaching in the intelligent era, the development of teachers' AI literacy level cannot be ignored. Countries around the world are actively developing teachers' AI literacy to cope with the development trend of intelligent education, and have issued a series of policies and guidelines to regulate its development. Based on this, this paper starts from the relevant policies and practical actions of teachers' AI literacy in various countries, and analyzes the urgent requirements of AI education for teachers' AI literacy from the aspects of teachers' consciousness and attitude, curriculum development, teaching development, teaching management, teacher development and AI ethics. Finally, the article clarifies the necessary qualities of teachers in the era of AI, and puts forward the development path of teachers' AI literacy in view of the above six aspects, in order to provide a reference for the professional development of teachers in the intelligent era.
