In order to promote the efficient development of generative artificial intelligence in the military field, this paper analyzes it. This paper significance of advanced research on the military application evaluation of generative AI, analyzes the basic principles that should be followed in the evaluation work, establishes the evaluation index system, studies the basic methods that should be adopted in the evaluation, and puts forward some thoughts on the military application evaluation of generative AI. The results show that this research can promote the close integration of generative AI and military applications, accelerate the technology landing and efficient development.
