This application provides a communication method and a communication apparatus. The method includes: A first device obtains a first function used to evaluate a resource consumed by a second device for executing an artificial intelligence AI model, and determines, based on the first function and information about a first AI model, a first resource consumed by the second device for executing the first AI model. The first device determines, based on the first resource, whether to send the first AI model or a manner of obtaining the first AI model to the second device. The first device evaluates, by using the first function, the resource consumed by the second device for executing the AI model, and determines, based on the resource consumed by the second device for executing the first AI model, whether to send the first AI model to the second device.
