Abstract: Disclosed is a method of providing information on a neural network model. The method includes receiving information on a target device and target performance of the neural network model; deriving information on a plurality of candidate neural network models; and transmitting a command to the external device to display information on the plurality of candidate neural network models, wherein the information on the plurality of candidate neural network models includes at least one of name of the plurality of candidate neural network models, performance of the plurality of candidate neural network models, or size of input data of the plurality of candidate neural network models.
