This application provides an artificial intelligence AI communication method, applied to any two devices that perform communication in a communication system. The method includes: A first device receives AI model information sent by a second device, where the AI model information includes M groups of AI model complexity information corresponding to M AI models, each of the M groups of AI model complexity information is time and/or energy consumption of executing one of the M AI models in each of N reference AI execution environments, and M and N are positive integers; and the first device sends feedback information to the second device. In this way, the first device can evaluate, based on the AI model information sent by the second device, matching between an AI capability of the first device and an AI model, so that simplicity, efficiency, and accuracy of an evaluation result of the first device can be improved.
